PetroChina Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project
On the morning of March 28, PetroChina’s Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project held a groundbreaking ceremony in Qinzhou.
As a key project of PetroChina’s “14th Five-Year Plan”, the Guangxi Petrochemical Refining and Chemical Integrated Transformation and Upgrading Project is a key project for building a new western land-sea corridor and participating in the RCEP international competition. The total investment is 30.45914 billion yuan, mainly including 1.2 million tons/ There are 14 sets of chemical units including annual ethylene, 2 sets of refining units including 2 million tons/year diesel adsorption and dearomatization, supporting newly built and renovated refining unit units and corresponding public works, storage and transportation and auxiliary production facilities.
This project is to build a new 1.2 million tons/year ethylene and downstream unit based on Guangxi Petrochemical’s existing primary crude oil processing capacity of 10 million tons/yearto realize the transformation and upgrading of refining and chemical integration. The oil refining block relies on the existing 30 sets of main production units. Newly built 2 million tons/year diesel adsorption dearomatization unit and 400,000 tons/year carbon dioxide The recovery unit (including a 100,000 tons/year catalytic dry gas carbon dioxide recovery unit and a 400,000 tons/year carbon dioxide recovery unit, built in the chemical industry zone), has decommissioned two main production units. After the completion of the project, the overall processing flow of the refining block will remain unchanged, and some of the refining product plans will remain consistent with the current situation. However, the annual production of gasoline and diesel will be reduced, and a large amount of high-quality raw materials will be provided for downstream ethylene units. The chemical industry block will build 14 new sets of main chemical equipment, including a 1.2 million tons/year ethylene unit, a 550,000 tons/year pyrolysis gasoline hydrogenation unit/styrene extraction combined unit , 180,000 tons/year butadiene extraction unit, 100,000 tons/year MTBE/butene-1 unit, 350,000 tons/year aromatics extraction unit, 400,000 tons/year full density polyethylene unit (FDPE ), 300,000 tons/year high-density polyethylene plant (HDPE), 300,000 tons/year tubular ethylene-vinyl acetate plant (EVA), 100,000 tons/year kettle-type ethylene-vinyl acetate plant (H-EVA) ), 400,000 tons/year polypropylene plant (PP), 50,000 tons/year hexene-1 plant, 27/600,000 tons/year propylene oxide/styrene plant (PO/SM), 300,000 tons/year The polystyrene unit (PS) and the 120,000/80,000 tons/year solution-polymerized styrene-butadiene rubber integrated unit (SSBR/SBS) mainly process different types of cracked raw materials from the refining block to produce high-density polyethylene (HDPE), linear Low density polyethylene (LLDPE), ethylene vinyl acetate (EVA), polypropylene (PP), butadiene, methyl tert-butyl ether (MTBE), butene-1, hexene-1, solution polybutyl Styrene rubber (SSBR), styrene-butadiene-styrene (SBS), propylene oxide (PO), styrene (SM), polystyrene (PS) and other major chemical products. At the same time, the environmental protection measures, storage and transportation systems, and public works of the entire plant will be newly built, renovated, expanded, or reused according to the process flow. Four new 5000m3 styrene storage tanks will be built in the reserved area of the terminal storage area;In addition, the existing benzene loading facility at berth 13# of the terminal will be changed into a benzene unloading facility. Two gasoline loading and unloading arms and one diesel loading and unloading arm in berth 11# were changed to benzene, toluene, and xylene loading and unloading arms respectively, and styrene loading facilities were added in berth 9#. At the same time, the environmental protection measures, storage and transportation systems, and public works in the terminal storage area and terminal will be newly built, renovated, expanded, or reused according to the process flow.
Huayi Qinzhou Chemical New Materials Integrated Base
The third phase of the methanol to olefins and downstream deep processing integrated project
On March 28, the opening ceremony of the methanol-to-olefins and downstream deep processing integration project of the third phase of Huayi Qinzhou Chemical New Materials Integrated Base was held in Qinzhou, Guangxi.
The total planned investment for the third phase of Huayi Qinzhou Chemical New Materials Integrated Base is about 55 billion yuan, with methanol to olefins as the leader. It mainly focuses on high-end new material products encouraged by the state, including EVA and other olefin downstream materials, biodegradable materials, polyurethane materials, polycarbonate and nylon 66 and other high-end engineering plastics, etc., to further promote the diversified and differentiated development of olefin downstream products at Huayi Qinzhou Base and enhance the competitiveness of the industrial chain.
Huayi Qinzhou Chemical New Materials Integrated Base is the largest industrial project in Guangxi to undertake industrial transfer from the east in recent years. The total investment of the project is about 90 billion yuan, and the designed output value exceeds 100 billion yuan. It covers modern coal chemical industry, light hydrocarbon cracking, salt The four major downstream industrial chains of chemical and petrochemical industries will be implemented in three phases. Huayi’s second phase of 750,000 tons of propylene and downstream deep processing integration project and chlor-alkali project started in November 2019 and will be completed and put into production in November 2022. The first batch of PVC products from the polyvinyl chloride (PVC) plant of the second-phase project successfully rolled off the production line, marking the official completion and commissioning of the second-phase project of the Qinzhou base and the beginning of the production stage.

Phase I (Industrial Gas Island Project): The total investment is about 16.2 billion yuan, and the annual output value is about 8 billion yuan. Construction started in November 2017 and will be completed and put into production in June 2021. It is also one of Guangxi’s “Ten It is the first 10 billion yuan major industrial project to be put into production during the Fourth Five-Year Plan period, and we also expect the output value of the first phase project to meet expectations!
The second phase of the 750,000-ton propylene and downstream deep processing and chlor-alkali project: a total investment of 18.9 billion yuan and a designed output value of 17 billion yuan. Construction started in November 2019.
The third phase of the advanced materials project was signed in Nanning on November 3, 2021. The project covers an area of about 7,600 acres, with a planned total investment of 55 billion yuan and an additional output value of 75 billion yuan. It is planned to build degradable materials, There are a total of 21 projects in the five major industrial chains including polyurethane, olefin materials, nylon 66, and acetic acid downstream. </span
