Catalytic cracking feedwater contamination
Thread Content
If the catalytic cracking feed contains water, it causes the pressure in the settler to rise suddenly before dropping sharply. The water in the feed leads to a rapid expansion of the volume within the settler, which results in an increase in pressure. I’m not quite sure why the pressure drops so rapidly afterward; those who know please explain, thank you
The catalytic cracking feed contains water, and the rapid expansion of water vapor leads to an increase in pressure in the settler； Subsequently, as the water vapor condenses or is removed, the volume decreases, and the pressure inside the settler drops as a result. .
There is no water left; there is water and oil, which causes unstable feeding to the nozzle
