It is the general trend for the market to utilize liquefied gasifiers well

On April 11, 2019, the 15th China Gas Industry Market Summit Forum and in-circle Fair were held in Chongqing. Mr.Liu Yanwei of Petroleum and Chemical Industry Planning Institute made a simple analysis of the LPG deep processing industry planning and made a feasibility study.

Firstly, Mr. Liu Yanwei gave a brief account of the supply and demand of liquefied gas resources. In recent years, China's crude oil processing capacity and oil supply and demand situation showed an increasing trend. LPG also increased steadily, the overall supply was less than demand. By 2018, China's liquefied gas supply was 38.81 million tons, and the demand was 55.86 million tons, which promoted the import of propane in China to rise year after year. By 2018, the import of propane was 13.46 million tons, and the import of butane was 5.36 million tons.

Then, the utilization path of liquefied gasifier is analyzed:

In the aspect of LPG consumption for civil combustion in China, the consumption proportion of LPG has been declining in recent years due to the influence of natural gas, LNG, dimethyl ether and other alternative energy sources as well as price changes. In the industrial field, industrial manufacturing and chemical raw materials are mainly used. With the continuous development and maturity of LPG deep processing technology and the upgrading of oil products, the consumption ratio of LPG is decreasing. With the lightening of olefin cracking materials, the application proportion of LPG in industrial field is increasing, and the consumption in commercial field is also increasing, while the development of LPG in transportation field is slow. With the upgrading of gasoline, alkylated oil plays an important role in the upgrading of gasoline quality. By 2018, China's production capacity of alkylated oil has reached 18.15 million tons per year. It is expected that in 2019, the region will add 2.52 million tons per year, and all of them will be put into operation for refineries. It is expected that from 2019, after ether emissions will gradually decrease or even disappear along the Yangtze River, East China and Northeast China. Overall, the rapid development of alkylated oils will lead to a reduction in the supply of carbon tetra resources after ether.

In addition, China is constantly developing new technologies. Sinopec Research Institute of Petroleum and Chemical Technology has developed solutions for the selective superposition-hydrogenation of tetraolefins and non-selective superposition-hydrogenation of butenes. The main components of mixed isohydrocarbons produced are isooctanes, which have high octane number and low vapor pressure. They are ideal gasoline blending components. Fuel ethanol production and promotion of vehicle ethanol gasoline implementation plan (September 2017), by 2020, the country will basically achieve full coverage. At last, Mr. Liu Yanwei concluded that due to the upgrading of gasoline quality, the large-scale production of alkylated oil in refineries and the lightening of olefin raw materials, the amount of carbon tetrachloride resources after ether is expected to be greatly reduced; the promotion of ethanol gasoline will lead to the withdrawal of MTBE, and a large number of isobutylenes need to find a way out, and theoretically the amount of resources will be greatly increased. However, at present, fuel ethanol by grain method is far from meeting the demand of ethanol and gasoline, so MTBE will be the main additive of gasoline in the near future. When to withdraw and when to withdraw is still a variable, we should be prepared in advance. With the rapid development of domestic PDH projects, the number of imported liquefied gas will increase rapidly, and we should pay close attention to the stability of foreign resources and cooperation mode. The utilization of chemical industry is the trend of the times. The market prospect of downstream products is good and the gross profit space is large. Therefore, it is necessary to intervene in advance.
