【Major Equipment in the Chemical Engineering Sector】Domestic production of 0.222–350,000-ton extrusion granulators
Thread Content
The past decade has been a period of rapid development in 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! *********************************** Following the successful commissioning at Longyou Petrochemical Company of the large-scale polypropylene extrusion granulation unit with a capacity of 200,000 tons per year, developed by Da Yaopu, the company manufactured an even larger version of such a unit – a 350,000 tons per year polypropylene extrusion granulator – which was successfully put into operation at Longyou Petrochemical Company in 2020. It produced qualified particles, and all technical specifications met the customer’s requirements. This marked Da Yaopu’s success in developing, delivering, and shipping two large-scale granulation units simultaneously, as well as in ensuring their proper operation.

To break the foreign monopoly on technology and markets, in August 2017, a joint research team composed of Sinochem (Guangdong) Refining & Chemical Co., Ltd., Sinopec Engineering Construction Co., Ltd., and Dalian Rubber & Plastic Machinery Co., Ltd. was formed to work on the localization of 350,000 tons per year polypropylene extrusion granulation units. During the research and development process, the project team thoroughly analyzed the key points, difficulties, priorities, and risks associated with the localization of these units, and conducted numerous simulation experiments, process tests, and verification tests. Through this effort, this \"**team\" managed to overcome nine major challenges related to machinery, electricity, instrumentation, and other areas within 19 months. It achieved innovative breakthroughs in theoretical analysis, experimental research, simulation, and design, ultimately mastering all the core technologies involved in the design, manufacturing, installation, commissioning, and operation of large-scale extrusion granulation units. At the delivery ceremony, Cao Xianghong, an academician of the Chinese Academy of Engineering, announced on behalf of the expert panel that the 350,000 tons per year polypropylene extrusion granulation unit had passed the delivery inspection. He said that the successful commissioning of the 350,000 tons per year polypropylene extrusion granulation unit has once again accelerated the process of local production of major petrochemical technologies and equipment. It will further break the technical and price monopolies held by a few international companies, curb the prices of similar products abroad, and safeguard **economic security.
