How many catalytic cracking units are there in China? Is a flue gas treatment unit installed behind each catalytic cracking unit?
The question you asked is too... difficult to answer. You might as well just state your motives or purpose directly.
Few people can give an accurate estimate of how many catalytic cracking units there are across the country. It is generally believed that a processing capacity of no less than 500,000 tons per year is required for the unit to be profitable.
I only know that CNPC has over twenty refining and chemical enterprises, with each one having one to three catalytic units. As for CNOOC, Sinopec, and local refineries, it’s not clear.
The answer on the 3rd floor was very professional. There is no range hood after the small catalyst.
