The methanol-to-olefin (MTO process for short) technology, developed by UOP, is adopted, and the supporting MTO-100 catalyst (SAPO-34) is used; Wison Engineering (China) Co., Ltd. is responsible for the detailed design and contract. The methanol is used as raw material for the unit, with a design treatment capacity of 750,000 t/year. The unit is mainly composed of the feed and product separation, reaction and regeneration, catalyst recovery systems, product compression and product concentration plants. featuring large scale, less personnel required, advanced technology, high integration degree and localization degree.

The olefin separation technology, an advanced technology independently developed by Wison with independent intellectual property rights, is adopted, and the pre-cutting - oil absorption and separation technology, with simple process, less equipment investment and low energy consumption, is used to replace the conventional cryogenic demethanization system, and to produce 286,000 t/year of polymer-grade ethylene and polymer-grade propylene.

The olefin cracking process (OCP process) and selective hydrogenation process (SHP process), jointly developed by Total Petrochemicals and UOP Company, are adopted, and the supporting OCP cracking catalyst and SHP hydrogenation catalyst are used. Wison Engineering (China ) Co., Ltd. is responsible for the detailed design and contract construction of the project. The C4-C8 heavy olefin products from MTO and OPU units are used as raw materials for the unit, to produce light olefin products with ethylene and propylene as target components. The unit is mainly composed of the selective hydrogenation, olefin cracking, regeneration gas compression cycle, cracking gas compressor and regeneration gas compressor, and other sections, and it has various noticeable features, such as many units, large scale, few personnel required, advanced technology, high integration degree and localization degree.

The second-generation low-pressure oxo synthesis through propylene rhodium, the liquid-phase circulation process, jointly developed by DAVY/DOW, is adopted, with an annual output of 250,000 t butyl octanol. The main products are octanol, isobutyraldehyde and normal isobutanol, all of which are important chemical raw materials for the production of plastics and rubber plasticizers.

The company has a special tank field for chemical products, with an area totaling 35,000 m3 and containing the octanol, butanol, isobutyraldehyde, propylene, ethylene, etc.
