【HaiChuan Chemical Project Updates】Zhejiang Petrochemical invests 34.5 billion yuan to build new facilities for 1.4 million tons per year of ethylene and related chemical products; project approved

Project Name: New 1.4 million tons/year ethylene and downstream chemical plants (Phase II project for product structure optimization)
Construction Unit: Zhejiang Petrochemical Co., Ltd.
Nature of Construction: New construction
Construction Content: This project includes a 1.4 million tons/year ethylene plant, a 750,000 tons/year pyrolysis gasoline hydrogenation plant, a 250,000 tons/year butadiene plant, 270,000/600,000 tons/year PO/SM plants, a 380,000 tons/year polyether polyol plant, a 400,000 tons/year ABS plant, a 100,000 tons/year cis-butadiene rubber plant, a 60,000 tons/year solution polybutadiene rubber plant, a 300,000 tons/year vinyl acetate plant, a 600,000 tons/year styrene plant, a 240,000 tons/year carbon dioxide recovery plant, a 200,000 tons/year ethylene carbonate plant, 100,000/30,000 tons/year styrene/ethylbenzene extraction plants, 400,000/250,000 tons/year phenol propylene plants, an 800,000 tons/year ethylene glycol plant, a 350,000 tons/year high-density polyethylene (HDPE) plant, along with supporting storage, transportation facilities, and auxiliary facilities. Construction location: Yushan Island Green Petrochemical Park, Daishan County, Zhoushan City, Zhejiang Province. Land area: 120.91 hectares (planned in conjunction with Phase II). Total workforce: 1,300 people. Total investment: 34.485 billion yuan

At present, the first-phase project, a refining and chemical integration facility with an annual capacity of 20 million tons, has been fully put into operation. Some units of the second-phase project, also with an annual capacity of 20 million tons, are ready for commissioning, and trial operations are being carried out step by step. In accordance with the requirements set forth by the Provincial Development and Reform Commission, the second phase of the project was optimized. Taking into account the current market conditions, it was decided to add 1.4 million tons per year of ethylene production capacity, along with 16 additional chemical processing units for the production of ethylene, propylene, styrene, polyether polyols, hydrogenated gasoline, solvated styrene-butadiene rubber, polybutadiene rubber, ABS, SAN, food-grade liquid CO2, ethylene carbonate, monoethylene glycol, diethylene glycol, triethylene glycol, HDPE, phenol, propylene, styrene, ethylbenzene, mixed xylene, and C9+ products. This project includes 16 production units such as ethylene plants. The storage and transportation facilities comprise a liquid storage and transportation system, polyether polyol filling stations, and systems for the storage and transportation of solid materials. The auxiliary facilities include membrane bag manufacturing plants and circulating water stations. All other storage, transportation, and auxiliary facilities will make use of the existing facilities at the Zhejiang Petrochemical Project. The components of the proposed project are shown in the table below.

Economic benefits: The total investment for this project of Zhejiang Petrochemical Co., Ltd. is 3,448,517 million yuan. According to preliminary estimates, the annual sales revenue is approximately 355,444.2 million yuan, with a post-tax net profit of 262,227 million yuan. The post-tax internal rate of return on the project investment is 11.77%, which is higher than the benchmark rate of 10%; thus, the project offers certain economic and social benefits. Features of this project: In line with the optimization plan for the second phase of the refining and chemical integration project, an additional ethylene production facility with a capacity of 1.4 million tons per year has been added, and a rational product portfolio has been planned based on the current market conditions. Make full use of the infrastructure from phases I and II; through the integration of upstream, midstream, and downstream industries within the petrochemical industry complex, achieve integration in resource allocation, integration in the construction of refining, aromatic compounds, and ethylene facilities, integration in the development of supporting facilities, integration in logistics and transportation, integration in environmental protection, integration in the comprehensive utilization of oil and coal, and integration in information management services. Adopt a development path characterized by scale, differentiation, uniqueness, diversity, and high-end orientation, focusing on the petrochemical processing industries with high added value and high technological content, striving to refine and optimize these industries in order to achieve the greatest possible economic and social benefits for the enterprises.

You observed quite carefully; I give you a thumbs up. :victory:

270,000 tons/year PO/SM unit + 600,000 tons of styrene, bringing the styrene production capacity to 1.2 million tons per year. There is no repeated route of aromatic hydrocarbons ==》PX ==》PTA ==》polyester.
