Stripping tower in oil extraction process

Stripping tower

Introduction of stripping tower in oil extraction process:

Stripping tower utilizes negative pressure to evaporate solvent at low temperature, which reduces solvent leaking,decreases solvent consumption and enhances oil quality.

Features of stripping tower in oil extraction process:
1. High efficiency, excellent desolventizing performance, low solvent residue in oil.
2. The stripping tower utilizes direct steam from desolventizer toaster and waste heat from steam-jet pump as heat source,  which saves energy, reduces space for condenser and needs less investment.
3. Low temperature creats final oil with better quality and lower solvent residue.

4. The stripping tower saves 20% energy, enhances oil quality and reduces refinery consumption, which decreases 15% production cost.

Working principle of stripping tower in oil extraction process:

Oil mixture is pumped into first evaporator, which operates at vacuum. Thus first evaporator can utilize indrect steam from desolventizer toaster as heat source, which efficiently saves energy.
After first evaporator, oil mixture is heated by crude oil from stripping tower, and then sent to second evaporator for second desolventizing, whose heat source is also indirect steam.
After second evaporatoe, oil mixture is sent to stripping tower, which operates with direct steam at vacuum, reduces volatile content less than 0.3%.
Generally speaking, stripping tower is necessary to large scale oil extraction process, such as soybean, rice bran and so on.
