How to determine the amount of stripping water for benzene extraction?
The amount of water used for stripping is primarily determined by the water content in the lean solvent
The most crucial aspect regarding this amount of stripping water is to ensure that the lean solvent regenerated in the solvent regeneration tower can be stripped away, as it serves as the carrier of energy.
With the bottom temperature and pressure of the recovery tower and regeneration tower held constant, the hydrocarbon content of the lean solvent and the amount of solvent regenerated serve as criteria for determining the amount of water required for stripping. The amount of water used for stripping is high, resulting in high energy consumption.
