Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with you here; we welcome everyone to participate more actively in the forum discussions. Be careful with fire risks as the heat increases in July. ---------------------------------------------In June 2019, the acceptance ceremony for Daqing Petrochemical’s 70,000 tons per year LLDPE domestic extrusion granulation unit was held at Dalian Rubber and Plastic Machinery Co., Ltd. Leaders and representatives from China National Petroleum Corporation, CNPC Daqing Petrochemical Branch, and Dayao Plastics Company attended the meeting, and witnessed the 70,000 tons per year LLDPE extrusion granulation unit successfully passing the factory acceptance test. Relevant leaders from China National Petroleum Corporation stated that this unit is PetroChina’s first domestically produced extrusion granulation unit, as well as the first domestic extrusion granulation unit capable of producing 70,000 tons per year of LLDPE. All of its technical specifications meet international advanced standards. As the first set of domestically produced extrusion granulation units developed by Da Yuanpu Company for CNPC, the R&D team overcame the key challenges related to the mechanical, electrical, and control aspects of this project through extensive research, simulation tests, process trials, and verification exercises. Following tasks such as drawing design, production and manufacturing, in-house assembly, and pre-shipment testing under both cold and hot conditions, this unit became a fully functional processing system featuring high levels of automation, visualization, and intelligence. Daqing Petrochemical’s 70,000 tons per year LLDPE mixing, extrusion, and granulation unit is a large-scale extrusion granulation system that was developed using its own technical capabilities; it possesses independent intellectual property rights and meets international contemporary standards. The successful development of this unit brings significant economic and social benefits.
