Large-scale cracking furnace involves raw material composition, energy consumption, output, economy and other issues, and the bigger the better. At present, the cost performance of single furnace10-150,000 tons/year cracking furnace is relatively high. There is even a cracking furnace with a single furnace capacity of 35wt/a in the Middle East, but its raw material methane content is very high. At present, domestic Huisheng and S.
EI's patented technology is not inferior to the top five foreign ethylene technology suppliers. At present, Huisheng is building an ethylene cracking furnace with a single furnace of 6.5438+0.92 million tons/year in Yangba Phase II.
