Description

technical field

[0001] The invention relates to a stripper internal component used in a catalytic cracking process and a setting method thereof. Background technique

[0002] Fluid Catalytic Cracking (FCC) is an important secondary processing process in the petroleum refining industry, which uses heavy feedstock oil to produce light oil products such as gasoline, diesel, and liquefied petroleum gas. The main steps are as follows, the hydrocarbon raw material is contacted with the hot regenerated catalyst in the riser, and the catalytic cracking reaction is carried out at 450 ° C ~ 550 ° C; after the reaction, the mixture of oil gas and the catalyst to be regenerated enters the settler, and is cyclone separated in the settler The unproductive catalyst is separated by the device and enters the stripper, while the oil and gas enters the subsequent product separation system. The raw catalyst is in countercurrent contact with water vapor in the stripper, and after removing the e...
