Product solutions
The specific product plans for this project are shown in the table below.
Process flow
(1) This project maximizes the use of naphtha, C5 fraction, and raffinate from the park’s refining projects as raw materials, and produces high-value propylene and ethylene-rich carbon dioxide dry gas through catalytic cracking to achieve refining and chemical integration. ;
(2) This project maximizes the use of purified syngas and propylene from the refining project as raw materials, and obtains high-end chemical products such as n-butanol, isobutanol and isooctyl alcohol through a series of processes such as catalytic oxo synthesis, hydrogenation and distillation separation. ;
(3) This project makes full use of part of the self-produced styrene, acrylonitrile and butadiene from the ethylene project to conduct graft polymerization to produce ABS general materials and special materials, extend the industrial chain, improve product utilization, and enhance product value;
(4) The project makes full use of the ethylene-rich gas produced by the K-COT unit to react with benzene from the refining project to generate ethylbenzene, which is then combined with propylene to generate propylene oxide and styrene through the propylene oxide-styrene co-production method. Most of them Improve product value;
(5) Preliminary chemical raw materials such as C4 raffinate and C4 alkynes are further processed into high-end chemicals such as butene-1 and polybutene-1, making full use of the advantages of refining raw materials to extend the chemical industry chain and create maximum economic benefits and social benefits. benefit.
The process routes adopted by each set of equipment in the project are as follows.
Material supply and consumption
The raw and auxiliary materials used in this project are shown in the table below.
Part of the naphtha, C5 fraction, raffinate, benzene, butadiene and other materials from the refining project in the park are sold as products (such as butadiene), and some are used as fuel (such as purified syngas) , and some are used as raw materials for other devices (such as naphtha). After the project is implemented, the existing refining and chemical projects will reduce the external sales of benzene, butadiene, and CO2. The purified syngas originally used in the fuel system will be replaced by the rich fuel gas of this project, and other refining operations will be reduced in accordance with the principle of less oil and more chemicals. The load of the device is used to supply naphtha, C5 fraction, raffinate, etc. for this project. Therefore, it will not increase pollutant emissions from the refining project.
Relying on storage and transportation projects
Hengli Petrochemical (Dalian) New Materials Technology Co., Ltd. plans to build a 1.6 million tons/year high-performance resin and new materials project (“Resin Project”), a 2.6 million tons/year high-performance polyester project, and a 600,000-ton industrial park in Changxing Island. /year BDO project, 1.6 million tons/year fine chemical project and follow-up projects. In order to better serve the planning projects, we conduct centralized design and planning of the supporting tank areas for each project. Hengli Petrochemical (Dalian) New Material Technology Co., Ltd.�The company plans to build a large-scale supporting tank farm and make overall planning to meet the storage and transportation needs of the planned construction project and subsequent projects.
Hengli Petrochemical (Dalian) Fine Chemical Park Storage and Transportation Project is located in Dalian Changxing Island Petrochemical Park, east of the resin project, about 100m away from the resin project land boundary. It is planned to build 23 tank groups, 19 chemical tank groups, and 4 spherical tank groups, with a total tank capacity of 567,000 cubic meters.
Project economic indicators
The main economic indicators are listed in the table below.
Project origin
In order to better adapt to market changes and enhance the company’s core competitiveness, Hengli Petrochemical relies on existing refining and chemical projects to implement chain extension and chain repair projects. It plans to build a 1.6 million tons/year fine chemical project to build Hengli’s integrated refining and chemical products. Naphtha, C5 fraction, raffinate, benzene, C4 alkynes, etc. are used as main raw materials to produce high-end chemical products such as styrene, acrylonitrile, ABS, polyether polyols, acrylic acid and esters, butyl-octyl alcohol, and realize corporate products Structural transformation and upgrading meet the “high-quality” and “high-end” development requirements of the 14th Five-Year Plan for the national petrochemical industry, and provide important support for Dalian City to build a 500 billion-level green petrochemical industry base.
Unit Overview
Hengli Petrochemical (Dalian) New Materials Co., Ltd. is affiliated to Hengli Petrochemical Co., Ltd., the core listed subsidiary of Hengli Group.
