What are the characteristics of the current domestic polypropylene plant production capacity? What are the characteristics of the different sources of raw materials in the production process, raw material supply, etc.? A group of big data tells you!
As of 2017, the capacity of polypropylene plants in China was 21.47 million tons, of which the production capacity of oil-produced polypropylene units was 12.46 million tons, which accounted for 58.03% of the total production capacity. The production capacity of MTO/CTO polypropylene units was 6.71 million tons, accounting for 31.25 of the total production capacity. %. PDH polypropylene plant capacity is 2.3 million tons, accounting for 10.71% of total capacity.
Oil-based polypropylene units in East China Ningbo Formosa and Xuzhou Haitian propylene need to be outsourced, involving a capacity of 650,000 tons/year, and the rest of the units are integrated upstream and downstream. Most of the polypropylene units in Shandong are integrated upstream and downstream, and Oriental Hongye is outside of propylene. Mining, involving a production capacity of 300,000 tons/year. The oil-produced polypropylene units in South China, North China, Central China, and Northwest China are integrated upstream and downstream units. The extraction of Yuntianhua Proton in the southwest region involves a production capacity of 160,000 tons/year. In the northeastern part of Daqing, the refinery part of the refinery is taken outside.
In the production process, the oil-produced polypropylene plant is mainly produced by the ring pipe method and the gas phase method. The domestic technology and the imported technology are all available. There are no obvious defects in all major regions. Among them, several sets of devices that have great influence in China, such as Shanzi Petrochemical, Maoming Petrochemical, Daqing Refinery, Yanshan Petrochemical, Sino-Korea Petrochemical, Fujian United, and other devices, the production process of most of the production line is Lyondell Basell's Spheripol process, which shows that the polypropylene unit was put into operation in the early stage, and the production enterprises have relatively recognized this technology. However, the later joint ventures such as the Fujian Joint and the Sino-Korean petrochemical joint ventures were put into operation and expanded, and the production process was a combination of the domestically produced circular pipe method and the imported technology.
The CTO and MTO devices are mainly concentrated in the northwestern region, mainly due to the abundant reserves of coal resources in the northwestern region and the convenient source of coal raw materials. The MTO devices are also conducive to the procurement of methanol. Most of the polypropylene plants have supporting upstream devices for coal. From methanol, methanol to polypropylene, the production process is diverse, including Dow's Unipol process, Innovene gas phase process, domestic second generation loop process, etc. However, Shenhua Yulin, China Coal Mengda is currently outsourcing methanol, and the production process is also Dow's Unipol process.
The PDH polypropylene plant was put into production, mainly in the coastal area, and the main supply bases were in East China and South China. The main reason is that propane needs to be imported, and the plant is put into operation in the coastal areas. The procurement of raw materials is relatively convenient. Shaoxing Sanyuan, Donghua Energy, Ningbo Fuji Integrated upstream and downstream unit, Fujian Zhongjing, Fujian Zhongjiang is currently outside the production of propylene, propane dehydrogenation unit is in production, has not yet been used. Hebei Haiwei is part of the outside acquisition of propylene, mainly due to propane dehydrogenation unit production is not stable, raw material source is insufficient Propylene extraction. In terms of production process, 4 sets of 6 sets of PDH polypropylene devices use the domestically produced pipe method process, Donghua Energy PDH polypropylene device uses the Unipol process, and Ningbo Fuki uses UOPC3Oleflex technology.
Polypropylene plant expected to be put into production in 2018, CNOOC Huizhou adopts Basell's Spheripolll double loop reactor, Zhongan coalition adopts Sinopec's SE-Oriental furnace technology with independent intellectual property rights, Qinghai Damme adopts Dow's Unipol process, and many processes go hand in hand. , Enterprises love each other.
