We must open "180" - Shaanxi Coal Group Yulin Chemical 1.8 million tons / year ethylene glycol project construction record

After five years of fighting, a modern chemical factory appeared on the Maowusu Desert, standing majestically like a steel jungle
.

"As the world's largest coal chemical project under construction, the Coal Fractional Utilization and Chemical New Material Demonstration Project carries the mission of transformation and upgrading of Shaanxi coal industry, and also shoulders the mission
of building a high-end energy and chemical base in northern Shaanxi 。 Yang Zhaoqian, secretary of the party committee and chairman of Shaanxi Coal Group, said that the project is divided into two phases of investment and construction, one of which is the construction of 1.
8 million tons/year ethylene glycol project (hereinafter referred to as the "180" project) and the pyrolysis start-up project of 15 million tons/year coal separation clean and efficient conversion demonstration project; The second phase is to build a 15 million tons/year coal separation clean and efficient conversion demonstration project olefin, aromatics and deep processing engineering
.

On October 9, the "180" project produced polyester-grade ethylene glycol products, completing the node target
16 days ahead of schedule.

Time goes back to April 15, 2020, on this day, the construction of the ground pipe of the ethylene glycol plant began, which is also the day
the construction of the "180" project began.

"At the beginning, we focused on the 12 major nodes, established a task list one by one in accordance with the working mechanism of localized management and designated responsibility areas, and took measures such as task reversal and time reversal to promote the construction of the project into the 'fast lane'
.
" Jing Ruilin, head of the ethylene glycol project department of Yulin Chemical Company of Shaanxi Coal Group, introduced
.

"Standards are norms, standards are rules
.
" This is a phrase
often said by Li Chengke, head of the company's ethylene glycol project department.
In line with the principle of "everything from zero, starting from zero", the company strengthens safety production standards and civilized construction management, and sets up a standardization promotion team to carry out special inspections on safety risks, hidden danger investigation, dust control, finished product protection, dust-free construction, etc.
, from steel structure frame installation to scaffolding erection, the degree of three-dimensional and visual engineering construction is increasingly obvious
.

In this year, with the efforts of all the construction personnel, the company has successively completed the task nodes of dimethyl oxalate (DMO) reactor, ethylene glycol reactor, dealcoholization tower, product tower and other task nodes, creating favorable conditions
for the comprehensive installation of steel structures, pipelines, electrical appliances, instruments and towers.

During the construction period, in the face of Yulin's unbearable summer heat, bitter winter cold, only one wind a year, the harsh environment from spring to winter, coupled with the new crown pneumonia epidemic sweeping the world to bring many challenges to personnel returning to the factory, equipment and material procurement and transportation, and construction coordination, the project construction fell into difficulties
.

What to do? Can't afford to wait! Slow down! Doing everything possible to speed up the project construction is the only choice
for Yulin Chemical Company.

The Yulin chemical people with torch-like eyes never give up, they hold their breath, face difficulties, and turn over against the wind
.
The company encouraged the confidence and determination
of on-site construction personnel to overcome difficulties through measures such as an open letter to all employees at the first time, the establishment of epidemic prevention and control work institutions, the issuance of epidemic prevention and control management measures, the establishment of a guarantee management system, the reserve of epidemic prevention materials, and strict control of internal and external inputs.

Since the outbreak of the epidemic, through the efforts of many parties, Yulin Chemical has become the first enterprise to obtain a permit to resume work in Yulin's projects under construction, and it is also a chemical enterprise
that has completed a total of 9.
708 million hours of safe working hours so far, and has not had a single personal injury accident or environmental pollution incident.

As long as there is no slippery slope in thinking, there are always more
solutions than difficulties.
In 2021, the company launched a series of activities such as "100 days of hard work" and "conference battle", and successively realized the intermediate handover of the first series of each plant of the "180" project, the first series of gasifiers had feeding conditions, and the DMO device I.
series of devices realized CCCC.
.
.
Behind these achievements, more than 20,000 people on site are racing against time to seize progress and create good results, and the project construction has once again accelerated
in an all-round way.

In January 2022 in Dabaodang, Shenmu County, the days and nights were long and the wind was cold, and the project site was still a busy scene, with traffic shuttling, machines roaring, and construction operations in various installation areas in an orderly
manner.

In order to open up the "180" project in the whole process, the company focused on all aspects of water combined transportation, air tightness, replacement, methanol washing, material start-up and output of qualified products, and strictly implemented the work of three inspections and four determinations, CCCC inspection, and problem rectification with a sense of responsibility of "always rest assured" and a meticulous and cautious professionalism, creating a Yuhua speed
that completed the intersection of ethylene glycol equipment in only 20 months.

"Every link, plan, operation ticket is our professional and technical personnel according to the site situation to explore the plan, and then distribute to the operator for inspection
.
Every bolt, gasket, and lead is reviewed by personnel at all levels and checked one by one
.
Wang Guanzhi, director of DMO equipment in the ethylene glycol project department, said and put the quilt on the back seat of his car into the
trunk.

It turned out that during the nearly 90-day test period, they hardly rested for 1 day, often taking a quilt in the car to deal with one night
.
These are probably the norm for most builders
.

On the day when the whole process of the "180" project was opened, a technician sitting next to the author picked up the glass bottle containing ethylene glycol products and casually said "it's worth it"
.
This sentence can not be calmed down in the author's heart for a long time, perhaps he, like all Yulin chemical people, has only one goal, that is, he must open "180"
.
