● China is the world's second largest ethylene producer and the world's largest ethylene consumer.
The localization of complete sets of ethylene technologies is of great significance
.
● China Olefins and Raw Materials Lightening Forum will be held in Beihai, Guangxi on June 10-11, 2020.
The conference will arrange industrial visits
.
● Expert leaders from China Huanqiu Engineering Co.
, Ltd.
will attend the meeting and give wonderful reports on "development of 1-million-ton ethylene complete process technology and its application in ethane/propane cracking and other projects"
.
Ethylene plants are at the "tip of the pyramid" of petrochemicals, covering almost all operating units of petrochemicals
.
Big ethylene is one of the three core technologies of Huanqiu
.
Since the first Daqing 600,000-ton ethylene plant using Huanqiu's independent technology was put into operation in 2012, Huanqiu's large-scale ethylene complete technology has been successfully applied to the first domestic coal-to-liquid by-product naphtha-to-ethylene plant - Ningxia of National Energy Group Coal Industry Group's by-product deep processing and comprehensive utilization project of 1 million tons/year olefin unit, Yuhuang ethylene, Luqing light hydrocarbon comprehensive utilization, Changqing ethane to ethylene, Tarim ethane to ethylene, Guangdong Petrochemical ethylene and other sets of units have formed A full range of large-scale ethylene complete sets of technologies capable of adapting to a variety of raw materials
.
In August 2019, Xinpu Olefins (Taixing) Co.
, Ltd.
designed and served by Huanqiu Company produced qualified ethylene products with an annual output of 1.
1 million tons/young hydrocarbon comprehensive utilization project.
The device ran smoothly, marking the successful start-up of the project
.
Using Huanqiu's own complete set of ethylene plant technology, and relying on the ethane resources associated with natural gas in Tarim Oilfield and the ethane resources associated with natural gas in Changqing Oilfield, PetroChina is building a 600,000-ton/year ethane-to-ethylene project in Tarim and Lanzhou Petrochemical Branch.
The company's Changqing 800,000 tons/year ethane-to-ethylene project
.
The two projects are China's first batch of ethylene production from pure ethane, and are national ethane cracking to ethylene demonstration projects jointly approved by the National Development and Reform Commission and the Ministry of Industry and Information Technology
.
In the face of the severe situation of the global spread of the epidemic and the decline of international oil prices, the ethane-to-ethylene project, as a key project for PetroChina's refining and chemical transformation and upgrading and a key project for PetroChina to create a world-class demonstration enterprise, is imperative to improve quality and efficiency
.
Ethane to Ethylene Project of PetroChina Tarim Oilfield Branch
Ethane to Ethylene Project of PetroChina Tarim Oilfield BranchPetroChina Tarim Ethane-to-Ethylene Project is located in the Petroleum and Petrochemical Industrial Park of Shangku High-tech Industrial Development Zone, Korla, Bazhou, with a planned land area of 147.
64 hectares
.
The total investment of the project is 9,051.
83 million yuan.
The main construction content and scale include 600,000 tons/year ethylene plant, 300,000 tons/year full density polyethylene (FDPE) plant, and 300,000 tons/year high density polyethylene (HDPE) plant
.
The ethylene unit adopts CNPC's own ethane steam cracking technology, the full density polyethylene (FDPE) unit adopts Unipol low-pressure gas phase fluidized bed process of Univation Company, and the high-density polyethylene (HDPE) unit adopts Lyondellbasell's Hostalen ACP low-pressure sludge process.

.
The project officially started on June 19, 2019, and is scheduled to be completed in June 2021

PetroChina Lanzhou Petrochemical Company Changqing Ethane-to-Ethylene Project
PetroChina Lanzhou Petrochemical Company Changqing Ethane-to-Ethylene ProjectThe Changqing Ethane-to-Ethylene Project of PetroChina Lanzhou Petrochemical Company is located in Yuheng Industrial Park, Yulin City, Shaanxi Province, with a total investment of 10.
86 billion yuan.
A new 800,000-ton/year ethane cracking-to-ethylene plant will be built, two 400,000-ton/year polyethylene units and a 20,000-ton/year hexene-1 unit will be built downstream of ethylene, as well as public works systems and auxiliary production facilities.
.
The foundation stone of the project was laid on September 4, 2019, and it is expected to be completed and put into operation in 2021
