Rapid expansion of production capacity to balance supply and demand of propylene oxide in China

The bottleneck of raw materials in the downstream industry can be solved, and the production capacity will expand rapidly. Imports will shrink year by year propylene oxide is an important chemical raw material. It can produce polyether polyols, and then produce polyurethanes. It can also produce widely used propylene glycol and non-ion. Surfactants, oil field demulsifiers, flame retardants, pesticide emulsifiers, etc.
Expansion of production capacity and a balance between supply and demand In the past 15 years, domestic demand for propylene oxide has grown rapidly under the influence of downstream derivatives. From 1991, the consumption of 50,000 tons has grown to 648 thousand tons in 2050, an increase of over 12 times. The average annual growth rate is as high as 22.6%. Among them, the total consumption of polyether polyol industry reached 550,000 tons, accounting for 84.9% of the total consumption, which is far higher than the global average. In recent years, with the rapid development of China's polyurethane industry, a large number of new and expanded polyether polyol plants have been built in China. The self-sufficiency rate of polyether polyols has been increasing year by year, and the self-sufficiency rate has reached 83.5% by 2005. The demand for propylene oxide is also greatly increased. increase.
Since 2006, CNOOC Shell's 250,000-ton/year plant has been put into operation, and Shida Shenghua’s 40,000-ton/year plant has been put into operation. In addition, Shandong Binhua’s plant capacity in 2006 has increased by 20,000 tons/year compared to the same period of 2005, and China’s propylene oxide production capacity has increased. It has exceeded 950,000 tons/year. With the large number of newly-built and expanded installations in China, propylene oxide has gradually shifted from supply shortage to balance.
In addition, the pace of foreign investment has accelerated. South Korea's Kumho Petrochemical Co., Ltd. and Jiangsu Jinpu Group formed a joint venture in September 2006 to form Nanjing Jinpu Jinhu Petrochemical Co., Ltd. The newly formed Nanjing Jinpu Jinhu Petrochemical Co., Ltd., relying on the industrial advantages of Nanjing Chemical Industrial Park, invested in the construction of a 100,000-ton/year integrated propylene oxide unit. Lyondell Chemical Co. and Sinopec Corp. signed a contract in February this year to build a world-scale propylene oxide/styrene monomer (P OSM) plant in Ningbo, and Leonard Chemical Co. offers its POSM technology. The plant's production capacity is 274,000 tons/year propylene oxide and 602,000 tons/year styrene, which is expected to be completed in 2009.
It is estimated that by 2010 China's total demand for propylene oxide will reach 1.28 million tons, and in 2009 China's total production capacity of propylene oxide will reach 1.585 million tons / year, when the domestic supply and demand balance, capacity slightly surplus.
The development of downstream industries has increased the gap between the supply and demand of propylene oxide and provided room for downstream development. Raw material bottlenecks in downstream industries have been solved. For example, alcohol ether, dimethyl carbonate, and propylene glycol industries have greatly increased output under the premise of abundant raw material resources. The import volume will shrink year by year.
Dimethyl carbonate is an important organic synthesis intermediate, especially in the synthesis of polycarbonate and gasoline additives have a broad market prospects. Since 2003, the domestic production capacity of dimethyl carbonate has expanded rapidly. Heilongjiang, Liaoning, Inner Mongolia, Shanxi, Shandong, Hebei, Anhui, and Xinjiang plans to build dimethyl carbonate-based dimethyl carbonate units. If these plans are implemented, the domestic dimethyl carbonate plant will expand at a rapid pace.
Propylene glycol is a raw material for the manufacture of unsaturated polyester resins, epoxy resins, and polyurethane resins. With the China National Offshore Shell 60,000-ton/year propylene glycol project being put into operation, the domestic production rate of propylene glycol will be greatly increased. As domestic propylene glycol-dimethyl carbonate equipment has certain advantages in production costs, domestic propylene glycol production will continue to grow steadily in the next few years, and imports will shrink year by year.
China's propylene oxide industry has made considerable progress, but with foreign advanced level and national confession hunters, we have to upgrade the value of 嬖诮 蚬ひ 蚬ひ ( ( ( ( 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ 蚬ひ. Magnesium is richer than 蚍(17)埂/TD>
