Condensation-adsorption combined process capable of improving the service life of oil vapor recovery system equipment

Abstract

The invention provides a condensation-adsorption combined process capable of improving the service life of oil vapor recovery system equipment, wherein the condensation-adsorption combined process has multiple treatment and recovery ways and good treatment and recovery effects. The condensation-adsorption combined process capable of improving the service life of oil vapor recovery system equipment provided by the invention comprises an inlet end, an exhaust fan, a primary condensing unit, a secondary condensing unit and an active carbon adsorption tank which are connected with one another sequentially; the active carbon adsorption tank comprises a first active carbon adsorption tank and a second active carbon adsorption tank which are connected in parallel; and a vacuum pump is connected between the exhaust fan and the active carbon adsorption tank. Due to adoption of coal based active carbon, the condensation-adsorption combined process has good mechanical property, excellent wearable effect and support force, and the stacking height being in a range of 30m. The sensibility of the coal based active carbon is lower than that of the active carbon fibers, so that the coal based active carbon can be used without a special filter system; and as the desorption temperature of the active carbon is normal temperature, mechanical wear caused by repeatedly increasing and reducing the temperature is avoided, and the utilization rate and the service life of the active carbon are improved.

Description

technical field [0001] The invention relates to a treatment system for organic volatilized gas, in particular to a condensation-adsorption combination process which improves the service life of oil and gas recovery system equipment with various treatment and recovery methods and good treatment and recovery effects. Background technique [0002] Existing oil and gas recovery technologies include carbon adsorption, condensation, membrane filtration, absorbent recovery processes and their combined processes. Carbon adsorption process is a commonly used process. However, due to the characteristics of activated carbon itself, the existing complete set of activated carbon combined process equipment, due to repeated vacuuming or steam desorption, and improper selection of operating parameters and activated carbon; the replacement cycle of most activated carbons is very short. Short, increased operating costs, so that environmental protection equipment can not get a good economic re...
