Please share your views on the industries you know.
Compound fertilizer production is relatively backward in technology. It is all technology from France, Norway, Sweden and the United States in the 1970s and 1980s.
The direct liquefaction of coal chemical industry to produce oil ranks first in the world. The cracking technology of petrochemical industry has entered the advanced ranks. Oil refining is at an above-average level. This post was last edited by Albertlu on 2009-2-24 14:39 ]
At present, domestic petrochemical development technology is relatively mature, but non-ferrous metal manufacturing is relatively lagging behind. This post was last edited by An Ran on 2009-2-24 15:45 ]
Who said compound fertilizer makes the world backward? Don’t you know Shanxi Tianji? It is definitely at the forefront of the world, but your factory is relatively backward, right?
The coal chemical industry is still relatively backward. The coal-to-liquid industry mentioned on the third floor is a high-energy-consuming industry, which is the most valuable industry in the world. There is a lot of room for improvement in the comprehensive utilization of coal. The utilization of coke oven gas has been improved. The utilization rate of coking crude benzene is not high. The separation degree and separation efficiency of coal tar are not high. More than 80 products can be separated from it abroad.
Coal gasification should be considered at the forefront of the world. Not only have more than 10 sets of new multi-nozzle opposed gasifiers been built or under construction in China, but they have also been successfully exported to the United States.
The pervaporation dehydration technology ranks first in the world. The world's most powerful pervaporation technology company is Sulzer. However, Sulzer membranes are too expensive. The price is about 10 times that of the domestic components of Tsinghua Lanjing Company, but the performance is not much different. Therefore, in terms of comprehensive performance and price, China is definitely number one. I have to thank the professors at Tsinghua University for this. It is their years of research that have led to this first achievement in China. Professor Chen Cuixian has made huge contributions to the research and promotion of permeable vaporization membranes.
