Condensation Adsorption Vapor Recovery Unit Fully Sealed Blower And Flanged Connection

Condensation-Adsorption Type Vapor Recovery Unit

* Summary

Vapor Recovery Unit is to collect the organic vapor discharged during the manufacturing, storage, loading and unloading processes of various industries and recycle it by means of condensation, adsorption, absorption, membrane separation, etc. so as to finally satisfy the emission standards and create certain economic benefits for the end user.

The Condensation-Adsorption Process adopts the method of cryogenic refrigeration to directly condense the light hydrocarbon contained in the vapor for the purpose of vapor recovery. The uncondensed gas containing small amount of oil vapor after condensation process shall be handled by means of adsorption in order to reach the emission standard.

The Condensation Process is suitable to handle the high concentration oil vapor. Generally, the capacity of treatment should not exceed 1500m³/h otherwise high energy consumption will be resulted. The oil vapor does not contact other liquid media, so it’s of simple process, visible & valuable benefit.

Principle / Flow Procedure

* Taking advantage of different condensation temperature of different compositions, the             Condensation Process reduces the temperature of the vapor and separates the desired                   composition when it changes into liquid.

* The poor gas containing small amount of oil vapor after condensation will be led to the adsorption       tank for further separation of hydrocarbons from the gas, so that the exhaust gas meets the                 emission standard.

* When the adsorbent is nearly saturated, the adsorption tank will be vacuumed by a dry screw             vacuum pump so that the adsorbed oil vapor will be released from the adsorbent. The released oil     vapor will be returned to the condensing device for treatment.

* The recovered liquid oil will be directly delivered to the product oil tank or raw material tank.
