PetroChina Guangdong Petrochemical Refining and Chemical Integration Project: Building a Refining City in a New Era

Guangdong Petrochemical Refining Area on the riverside of the sea

Editor's note: In the 60s of last century, China's petrochemical workers shouldered the heavy trust of the country and the needs of the industry, overcame many difficulties on the basis of the extremely weak oil refining industry, and independently developed five refining technology processes such as fluid catalytic cracking, catalytic reforming, delayed coking, urea dewaxing, new catalysts and additives, and watered the "five golden flowers"
of the refining industry.
Since then, China's oil refining industry has been born from a barren land
.

60 years after the bloom of the "Five Golden Flower", PetroChina's five representative refining and chemical projects have once again shined, writing a new chapter
in the high-quality development of China's petrochemical industry in terms of breakthrough in independent technology, implementation of oil reduction and increase, commitment to transformation and upgrading, realization of green and low-carbon, and promotion of local economy.
Today, let's set our sights on the new "golden flowers" and see what kind of gorgeous scenery
they have brought to the land of the Republic.

Dananhai Petrochemical Industrial Park in Jieyang City, Guangdong Province is located on the coast of the South China Sea of the motherland, where the Longjiang River enters the sea
.
For thousands of years, the sea has impacted the years, and the journey of the sun and the moon is out of it; Fishing boats carry legends, and they lead boats on the shore and fight with criminals
.
This land of eight or nine square kilometers was a deserted beach a few years ago and sparsely
populated.
But now, tower cranes are lined with pipe networks, and PetroChina Guangdong Petrochemical Refining and Chemical Integration Project (hereinafter referred to as Guangdong Petrochemical Project) has landed here
.

On October 26, the atmospheric vacuum distillation unit II of Guangdong Petrochemical Project successfully introduced crude oil, and the project fully entered the stage of trial production of feeding
.
As the sun rises, the golden morning sun falls on the silver steel forest, this petrified pearl radiates dazzling brilliance, and a new era refining city is rising
.

Entrepreneurship! A relay across time and space

Illuminated installation area

On the eve of the tenth anniversary of the National Day in 1959, the Daqing oilfield was born
.
In the 60s of last century, the vigorous Daqing Oil Battle created a miracle
in the history of world oil development.
Since then, several generations of Daqing people have worked hard to build China's largest oil production base
in the ancient wasteland.

"Today, the baton of entrepreneurship has been solemnly and gloriously handed over to us
.
" Kang Zhijun, Secretary of the Party Committee and Executive Director of Guangdong Petrochemical Company, said, "During the construction process, we have always regarded the study and implementation of the spirit of General Secretary Xi Jinping's congratulatory letter to the 60th anniversary of the discovery of the Daqing oilfield as an inexhaustible driving force
to forge ahead.
”

From the 60s of the last century to the beginning of the 21st century, from the black water of the White Mountains to the coast of the South China Sea, this is a relay across time and space
.

According to reports, Guangdong Petrochemical Refining and Chemical Integration Project is a strategic project for the transformation and upgrading of China's petroleum refining and chemical business, and it is also the largest one-time refining project of CNPC, covering an area of 920 hectares, with a construction scale of 20 million tons / year of oil refining, 2.
6 million tons / year of aromatics, 1.
2 million tons / year of ethylene, is the only refining base
at home and abroad that can all process inferior heavy oil.
The project has been fully started construction since the end of 2018 and is currently in the production preparation stage, and is scheduled to be completed and put into operation
by the end of this year.
The project will build PetroChina South Refining and Chemical Base and the largest integrated refining and chemical production base
in South China.
The aromatic hydrocarbon plant, polypropylene plant and styrene plant of the project are the largest
single set in the world.

At the project construction site, various commando teams fought on all fronts of project construction
.
Since 2009, in order to support the construction of Guangdong petrochemical projects, countless petroleum people have traveled thousands of miles from the northeast, northwest and even all directions of the motherland to the South China Sea to participate in the construction of this southern refining and chemical base of PetroChina
.
Under the inheritance and inspiration of the Daqing spirit and the iron man spirit, the vast number of cadres and workers have worked hard to seize the day, and a world-class refining and refining base is about to bloom with dazzling light
.

Compete for excellence! A drawing of the world

Panorama of Guangdong petrochemical plant

From the beginning of the construction of the project, PetroChina was determined to benchmark against the international advanced level and build it into a green, intelligent and cost-effective world-class "refining and chemical giant"
.

According to reports, the project adopts advanced technology at home and abroad, optimizes the composition and process flow of oil refining, aromatics and ethylene raw materials through the unique deep processing route of heavy and inferior crude oil, and realizes "suitable oil and oil, Yifang and ene"
.
Compared with refineries of the same scale, the added value of products of refining and chemical integration enterprises can be increased by 25%, and energy consumption can be reduced by about
15%.

At the same time, after the comparative demonstration of more than 240 specific schemes, Guangdong Petrochemical has optimized the project from simple refining to refining and chemical integration, and carried out a comprehensive top-level design and deployment from "clean production process, efficient resource utilization, optimized product structure, maximum energy conservation and emission reduction, systematic pollution prevention and control, and intelligent environmental supervision", and won the "starting line" advantage
on the road of green, low-carbon and circular economy construction and development from the beginning.

They insist on environmental benefits
from advanced processes.
The pressure reducing system of the atmospheric pressure reducing device adopts Shell decompression deep drawing technology, the aromatic hydrocarbon combined unit adopts the latest generation of light desorption agent simulation moving bed process technology of UOP company, the ethylene cracking unit adopts the pre-propane pre-hydrogenation technology independently developed by PetroChina, and the styrene plant adopts the process technology of ethylbenzene catalytic dehydrogenation to styrene from Rumus.
.
.

They insist on environmental benefits
from advanced processes.
The project aims to improve the efficiency and cleanliness of the whole process processing route, such as effectively removing impurities
from raw materials during the processing process.
In terms of main technical and economic indicators, the key technical and economic indicators such as comprehensive energy consumption, light oil yield, processing loss rate, comprehensive commodity rate, diesel-to-steam ratio, ethylene energy consumption and other key technical and economic indicators designed by the project with the standard of "stop at perfection" are at the advanced level
of the industry.

They insist on environmental protection benefits
from advanced supporting facilities.
The project has built PetroChina's first sewage plant using Siemens powder activated carbon treatment + wet oxidative regeneration (PACT+WAR) process to treat highly saline sewage, of which WAR treatment scale is the largest in domestic petrochemical enterprises and has the largest emergency receiving capacity
of accident sewage of PetroChina.
At the same time, the new solid waste incineration system with a treatment capacity of 60 tons/day adopts rotary kiln incineration technology to harmlessly and reduce the organic residues, waste coke, waste activated carbon, biochemical sludge, etc.
of each device
.
They also introduced a comprehensive utilization project of petroleum coke hydrogen ash to improve the level of on-site treatment of
resources.
At the same time, various "sound environment" protection measures have been designed and constructed
.

Digital transformation and upgrading is an inevitable trend
for modern petroleum and chemical enterprises to achieve high-quality development.
Guangdong Petrochemical has established a unified master data management system for intelligent factories in the comprehensive database of enterprises, integrating the data of more than 20 systems of planning, production, storage and transportation, equipment, energy, safety and environmental protection, and operation of seven major businesses, forming a highway with extensive access to business system data, so that the data of the whole plant can flow freely, so as to realize data sharing and "counting out one source, providing on demand", and eliminating data islands
from the source.

The use of advanced digital management and control system has also given wings
to the intelligent construction of the project.
Refining and Chemical Operation System (MES), which allows management and scheduling to be on the "construction site"; Production Collaborative Optimization System (PSO) to provide optimal scheduling scheme for device commissioning; Refining material optimization and scheduling system (APS) to quickly optimize product production solutions; Storage and transportation logistics automation system, so that logistics flow accurately and quickly.
.
.
At present, Guangdong Petrochemical is hitting the goal of full start of production, and the smart factory project has 27 systems in trial operation, of which data centers, cloud platforms, network systems, etc.
have been completed and put into use in the first half of this year, and it is expected that the smart factory systems will be fully put into use
at the end of December this year.

Stand up! A call to lead the way

Guangdong Petrochemical stands on the coast of the South China Sea, lays out future development, leads industry transformation and upgrading, drives regional economic growth, and ensures national industrial security
.
On this banner is the mission and responsibility of PetroChina as a central energy enterprise; Under this banner, it is the wisdom and practice
condensed by the "Golden Flower" brand in the new era.

In recent years, PetroChina has vigorously promoted the transformation and upgrading of refining and chemical business, further deepened the development pattern of "three regions and one base" and the development positioning of enterprises, promoted the gradual transformation of refining and chemical enterprises from "fuel type" to "material type", promoted the transformation of olefin production raw materials to diversified and low-cost, and promoted the transformation
of chemical products to high-end.

As the southern refining and chemical base in the "three regions and one base", Guangdong Petrochemical Project is a 10-million-ton refining and chemical integration project laid out by PetroChina in the eastern coastal area of Guangdong Province, and is the only refining and chemical base at home and abroad that can process all inferior heavy oil, and it is also a successful practice
to realize the domestic refining and chemical business to move towards the middle and high end of the industrial chain and value chain.
After the project is put into operation, it will give full play to its adaptability to heavy and inferior crude oil at home and abroad, eat "coarse grain" to produce fine products, and enhance the flexibility and safety
of the introduction of national foreign trade crude oil.

South China is a world-class manufacturing base and a major consumer of
domestic chemical products.
According to the data, as of the end of 2021, the domestic supply gap of raw materials for chemical products such as high-density polyethylene, linear low-density polyethylene, polypropylene, and ABS plastic resin in South China was nearly 9 million tons/year, and the external dependence reached 46.
8%.

After the project is put into operation, it will increase the domestic supply, local supply and partition supply of chemical raw materials for chemical products in South China, especially in the Guangdong-Hong Kong-Macao Greater Bay Area, by nearly 2.
5 million tons/year, further meeting the demand
for chemical raw materials in the region.

It is reported that the Guangdong petrochemical project is expected to achieve annual sales revenue of 82 billion yuan, achieve profits and taxes of 20 billion yuan, and the engine effect formed can improve the petrochemical industry chain in eastern Guangdong, accelerate the formation of a trillion-level green petrochemical industry base, and further improve the level of
coordinated regional development in Guangdong Province.
At present, with this project as the leader, Jieyang Dananhai Petrochemical Industrial Park has successfully signed new materials, fine chemicals, biomedicine high-quality chemical industry projects, with a total planned investment of 100 billion yuan
.

Fight! Perseverance without fear of wind and rain

Behind the world-class "refining and chemical giant" of the Guangdong Petrochemical Project, there is such a set of data: more than 600,000 design drawings, 10,418 process equipment, 4.
11 million cubic meters of concrete, 270,000 tons of steel structure, and 3,377 kilometers of process
pipelines.
Someone has calculated that the concrete used in the project can pour 22 bird's nests, the steel structure can build 41 water cubes, and the pipeline can be paved from Beijing to Guangdong
.

The construction period is tight, the task is heavy, the management interface is complicated, and the construction organization is difficult.
.
.
are important challenges
that project builders must overcome.
At the same time, the project site has a humid subtropical monsoon climate, with an average annual precipitation of between 1720 and 2100 mm, and is often hit by severe tropical storms in summer and autumn
.
During the rainy season from April ~ July, moderate to heavy rainfall can be intermittent for one month
.
In August, typhoon activity was frequent, and once the strong convective weather came, the project construction site turned into a country
in an instant.
On the South China Sea, rain and sunshine do not bring coolness, and whenever the rainstorm passes, the hot sun will vaporize the stagnant water on the ground into the air, and the relative humidity of the air will reach more than 90%, and the construction personnel will be like being in a steamer
.
Sweating on sunny days and mud on rainy days is a true portrayal
of builders.

It is in this harsh natural environment that the project construction is also facing many problems
such as the difficulty of organizing construction manpower and hindering the arrival of imported equipment brought about by the new crown pneumonia epidemic.

In order to complete the construction task on schedule and with high quality, the cadres and employees of the project construction jointly carried forward the spirit of petroleum and the spirit of Daqing iron man, took the project construction as their home, worked hard and united as a city, continuously improved work efficiency, innovated construction methods, and accelerated the project construction
.

The soldiers and horses did not move, and the grain and grass went
first.
The arrival of refining process equipment on schedule is an important prerequisite
for the smooth progress of on-site construction.
In June last year, due to the influence of the southwest monsoon, six transport ships carrying 16 heavy equipment were stranded at sea, but they were unable to berth
at hand.
Seeing that the "Fireworks" and "Chapaca" double typhoons are about to hit, if the goods cannot be unloaded on time, the construction period
will be seriously delayed.
The company immediately set up a coordination special class, 24 hours to keep an eye on meteorological and sea state changes, project members stationed at the wharf, eat and live on the front line, actively coordinate large-scale transportation, organize docking meetings for maritime equipment problems for many times, study and form the optimal unloading plan, seize the only 72-hour favorable window period for wind direction change, continue to fight, seamless connection, and finally safely unload all stranded equipment, winning the initiative
for project construction.

It is worth mentioning that Guangdong Petrochemical has a total of 406 sets of maritime equipment, modules and accessories, with a total of 105,000 tons, of which the shipping rate of heavy equipment of more than 150 tons is 100%, and the total amount of maritime equipment is the heaviest and largest
in the construction of similar projects in China.

When the equipment arrives, on-site hoisting is another "roadblock"
in the construction of the project.
Guangdong Petrochemical's multiple sets of production equipment have reached the leading scale in China and even the world, and how to safely and smoothly lift these tall and heavy "big guys" into place is the key
to ensuring the progress of project construction.
The project team innovatively formulated a "four unified, one centralized" heavy equipment lifting plan
.
Engineering personnel are closely organized and coordinate multiple resources to form a joint force; Technical experts repeatedly calculate to give full play to the maximum performance of lifting equipment; Project supervision and sales inspection, strict control of on-site operation safety.
.
.
.
.
.
At the hot construction site, a magnificent picture of iron arms slowly spreading
.

On November 15, 2021, with the successful placement of the styrene separation tower, the lifting task of 25 1,000-ton large-scale equipment of Guangdong Petrochemical was successfully completed
.
During this period, the project set more than 100 domestic and foreign industry records
, including the completion of Asia's largest aromatic residual liquid tower "dressing and hating" in 29 days, and ethylene installation tower in three days and two cranes.
In addition, the project department has taken a series of measures to lock in the red lines
of safety, environmental protection, quality and epidemic prevention.

Today, the project is about to be put into operation, more than 2,100 company employees, more than 300 start-up experts, more than 3,500 business outsourcing personnel are all in place and put into battle, more than 80,000 pipeline purging, 110,000 loop tests, 170,000 instrument single point tests, and 5,000 machine pumps are being tested in an orderly manner
.

"More than ten years of perseverance and more than 1,000 days and nights of hard work are about to bear the fruit of victory, and our hearts are surging and full of emotion
.
" Kang Zhijun said
.

Gift! A confession that does not change its original intention

On October 13, the 500,000 tons/year polypropylene plant completed the commissioning of extrusion granulation materials

"I give oil to the motherland" was the most affectionate confession
of Chinese oil people to the motherland.
In the Guangdong petrochemical project, the original intention of this confession has not changed, and this kind of affection is generally the same
.
The surname of the party for the people, prosperous industry and serving the country, is the foundation of PetroChina, and also the foundation
of Guangdong petrochemical project.
Party building led the whole process
of project construction.
On September 21, Dai Houliang, Chairman and Secretary of the Party Group of CNPC, and his entourage fully affirmed
the project to promote high-quality construction with high-quality party building.

Party organizations at all levels of the company deeply promote the deep integration of party building work with central work such as starting and putting into production, safety and environmental protection, maintaining stability, and production preparation, build a scientific and complete party building work system, and grasp various measures
to improve the quality of grassroots party building work.

The company earnestly carries out the study of the party's latest political theory, uses the first topic and the theoretical central group of the party committee to follow up and study the party's latest theory, insists on taking the study and education of party history as a major political task, and comprehensively carries out the post practice activities
of "oil workers' heart to the party and make meritorious contributions to the new journey" 。 Party organizations at all levels have taken on the role, from the establishment of the first shock team to the formation of 58 shock teams of party members, the creation of 44 party member responsibility areas and 101 party member demonstration posts, organized party members, mobilized the masses, and united all parties involved in the construction, giving full play to the role of party branches as fighting fortresses and party members as vanguard models, so that the "soft power" of party building work has been transformed into "hard support"
for accelerating the high-quality construction of projects.

The "dressing and hatting" of the aromatic hydrocarbon residual liquid tower "dressed and hatted" in only 29 days completed the "dressing and hatting" of the largest aromatic hydrocarbon residual liquid tower weighing more than 4,000 tons in Asia, and snatched back the entire 26-day construction period, 6 days earlier than the assault time; The "dressing and hatting" commando team of the quenching oil tower and the quenching water tower completed the "wearing clothes and hats" of the 1.
2 million tons/year ethylene installation twin towers in only 28 days, and realized two cranes in three days for the oversized tower; High-density polyethylene sewage tank pouring construction, the party member commando team achieved 1586 cubic meters of concrete pouring in 16 hours.
.
.

In the process of fully promoting the implementation of the theme education of "changing ideas, bravely taking responsibility, strengthening management, and creating first-class", Guangdong Petrochemical Company encourages party members and employees to innovate and create results through activities such as "big discussions" and visiting red bases to relive the oath of joining the party, and transforms learning results into "golden keys"
for solving problems, improving quality and efficiency, and promoting project construction 。 After four months of all-out assault, the five pipeline pressure test commando teams of oil refining production completed the pressure test of 1458 pressure test packages with high quality; The adsorbent loading commando team of the four aromatic hydrocarbon combined units of oil refining production worked hard and skillfully, and the charging speed was increased from 40 barrels per hour to 77 barrels per hour.
.
.

Today, the project construction has entered the stage
of starting and putting into production.
The commandos fought on all fronts, the team flag was planted all over the scene, and pride overflowed in
the chest.
Look, this shadow of steel is a hot-blooded soul
.
Listen, this winter story is the song
of spring.
Party members are using their unity, wisdom and diligence to establish meritorious achievements to escort the high-quality construction of the project; Create great deeds with their loyalty, conviction and affection, and pay tribute to the party and the country
.

The refining city of the new era has stood majestically, and the dream of the industry of the new era is shining into the world!
