On May 20, 018, the Yan'an Nenghua project 450,000 tons/year of polyethylene device particles received the hopper sampler outflow, indicating that the world's single largest production capacity of the extrusion granulation unit 60% load a successful test, the output is qualified Polyethylene pellets. The extrusion test of the extrusion granulator took 4 hours and created a new height in the test run time.
Since China's first coal-based polyolefin plant, Shenhua Baotou, commenced production in 2010, coal-based polyolefins have mushroomed, and especially after 2013, the process has gradually matured and developed rapidly. As of the end of the current domestic coal-based polyolefin production capacity A total of 9.22 million tons/year broke the pattern of the two-barrel oil-sharing market.
At present, China's polyethylene still has 60%-70% of its demand for imports, especially for HDPE and high-end LLDPE. Afterwards, LLDPE and HDPE are the main devices that will be put into operation. This will continue to fill domestic demand to some extent. The resources are vacant. At present, the country is gradually increasing the refinement of the industry, stabilizing the differentiated and high-performance lines, and moving toward high-end products. There is still some way to go before the domestic production capacity meets self-sufficiency.
