    Adsorption-Absorption Technology for Vapor Recovery Unit


    1. 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 oil vapor handled by adsorbent will satisfy the emission standard and be discharged directly. The organics separated will be adsorbed and enriched in the adsorbent. When the adsorbent is nearly saturated, vacuum will be created to have the oil vapor adsorbed released from the adsorbent. The oil vapor released will be absorbed by liquid oil spray and then returned to the product oil tank or raw material tank for the purpose of oil vapor recovery.


    Adsorption process is ideal for the oil vapor of low concentration. The emission after treatment can satisfy stringent national or local standards. The Adsorption-Absorption Process is featured by reduced investment, easy operation, high recovery efficiency and low energy consumption.



    1. Work Principle / Flow Procedure

    Taking advantage of different bonding force between the various compositions and the adsorbent, the adsorption process can first separate those difficult to be adsorbed from the others and then the organics apt to be adsorbed get enriched in the adsorbent. Clean emission after treatment then is directly discharged into the atmosphere. When the absorbent is nearly saturated, a vacuum atmosphere will be created in the adsorption tank by a dry screw vacuum pump so that the compositions collected in it vaporize and escape. The oil vapor released is then led to the absorption tower and caught in the absorbent. The liquid oil recovered can be delivered to the product tank or raw material tank requiring no further separation and purification. The absorbent SMDERI uses is the coal based dedicated activated carbon of oil vapor.
