High Concentration Oil Vapor Recovery Unit By Condensation Adsorption Technology - China

High concentration oil vapor recovery unit by condensation-adsorption technology I Work principle Taking advantage of different condensation temperature of different compositions, the Condensation-Adsorption Process adopts cryogenic refrigeration method to cool down the oil vapor and then directly separate and condense the light hydrocarbons contained in the vapor for the purpose of recovery.

The remaining uncondensed gas containing small amount of oil vapor after condensation process is delivered 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 further treatment.

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

II Advantages Especially suitable for high concentration oil vapor, the condensation-adsorption process is featured by the following advantages: 1) High oil recovery efficiency and low energy consumption; 2) One work heat exchanger together with a standby unit provided at the condensation section to ensure continuous operation; 3) Special three stage condenser system for oil vapor of complicated compositions; 4) Delivered as a skid to reduce site installation work; 5) Fully sealed blower and flanged connection in the skid to achieve zero leakage; 6) ExdIIBT4 or ExdIICT4 explosion proof.

III Components and parameters The vapor recovery unit of condensation-adsorption technology mainly is made up of condensers, adsorption tanks, compressors, vacuum pump, drain pump, stack and etc.
