Three-phase separator in catalytic cracking
Thread Content
Do oil and water come into contact in the oil-gas-water three-phase separator during catalytic cracking? ?
The oil level is 30%, the lower limit is 50%, and the full scale of this limit is 100%. So how is the empty space above 50% in contact with it?
The interface position refers to the location where water and oil meet. As you said, the lower 50% is water, while the upper 50% is oil; above that is the oil level, and beyond that is the gas phase
The concept of “four understandings and three skills” does make sense; if you look at the structure and principle of a three-phase separator, you’ll understand a lot! http://www.chinabaike.com/uploads/allimg/141009/0321564R7-1.png http://v.youku.com/v_show/id_XNDc3MTMyMDEy.html?tpa=dW5pb25faWQ9MzAwMDAzXzEwMDAxNF8wNF8wMQ&fromvsogou=1
The level display section is mainly used to show the level of acidic water, while the empty area above it represents oil. The oil level indicator shows the gas phase on top; do not get confused by the labels on the system screen, as they indicate a control value rather than the actual oil level.
