Liaoning Province's “30-350 thousand tons/year LLDPE double-support continuous mixing extrusion granulation unit” developed by Dalian Rubber & Plastics Machinery Co., Ltd. is a major special project of scientific and technological innovation, recently attended by the Science and Technology Department of Liaoning Province. Acceptance and acceptance, the project passed acceptance once.
China's ethylene industry has entered a period of rapid development, especially the coal-to-olefin ethylene project, which has developed rapidly in recent years. The large-scale double-support continuous mixing extrusion granulation unit is a major petrochemical key equipment urgently needed for domestic production of ethylene engineering. In petroleum refining and coal chemical olefin granulation process.
The company has completed a series of research and development work on the design, manufacture, installation and commissioning, and operation management of this large granulation project, achieving intelligent control of the unit's one-click driving, and overcoming large-scale and complicated profiles. Integral rotor, large barrel, double output shaft super high torque reducer, large displacement melt gear pump and underwater pelletizing system and other key components of the design and manufacturing of key technologies. At the same time, the unit as Zhongtianhechuang Ordos An important part of the 1.37 million tons coal-to-olefins project in the coal chemical project has undergone a full-load performance test. After application verification, the major performance indicators have reached the international advanced level, and the project crew can replace imports, breaking the long-term foreign technology and price monopoly. 5. It is of great significance to promote the rapid development of China's coal to olefins and petrochemical refining and ethylene industries.
