【Major Chemical Equipment in China】061 – Completion of the acetylene cracking gas compression unit for a major domestic project
Thread Content
The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and increased use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! *********************************** In February 2022, the acetylene cracking gas compression unit, a major domestic project jointly developed with the 711 Institute of China State Shipbuilding Corporation, successfully passed the equipment delivery inspection. The acetylene pyrolysis gas compressor is a key piece of equipment in the biodegradable materials industry chain. Since the pyrolysis gas contains reactive acetylene, which can easily lead to decomposition and explosion, higher technical and safety standards are required for the compression process. For a long time, the compressor market for acetylene production facilities in our country has relied entirely on imports; long supply lead times, high product prices, slow service response, and delayed delivery of spare parts have severely hindered the development of related industries. Building on the earlier localization of acetylene vacuum compressors, Institute 711, together with industry experts from companies such as Wanhua Chemical and Chengda Engineering Company, formed a technical team to work on the localization of large-scale two-stage pyrolysis gas compressor units. Through the joint efforts of the project team, various technical challenges were overcome, and all tasks related to the research, development, design, and production of the unit were completed within just one year; the team also mastered the technology for designing pyrolysis gas compression units as well as for system integration.

The management recently asked to investigate acetylene compressor manufacturers; it’s a bit concerning. https://bbs.hcbbs.com/thread-3225581-1-1.html (Source: Huahai Chuanliu – Haichuan Chemical Industry Forum)
On March 22, 2021, the official website of Meishan City published the first public notice regarding the environmental impact assessment for Wanhua Chemical (Sichuan)’s integrated project to produce 75,000 tons of polylactic acid per year; the company plans to build a facility with an annual production capacity of 75,000 tons of polylactic acid as well as other supporting facilities in Meishan, Sichuan. Polylactic acid, also known as polylactide, is a polyester polymer synthesized from lactic acid as the main raw material. It is a new type of biodegradable material, and given the increasingly strict policies on plastic use, it holds great market potential in the future. In addition to polylactic acid, the company has also set up a production facility for PBAT with an annual capacity of 60,000 tons at its Meishan site; trial production of this facility began at the end of 2021 ； At the same time, the company has also established a production capacity of 100,000 tons per year of BDO using the natural gas acrolein method; once the project is operational, it will achieve self-sufficiency in raw materials, thereby highlighting its integrated advantages.
