Absorption method utilizes the adsorbent such as active carbon, silica gel to the size of oil gas/air gaseous mixture absorption affinity, realizes being separated of oil gas and air.Oil gas is by adsorbents such as active carbons, and oil-gas component is adsorbed on adsorbent surface, and then through decompression desorption or steam desorption, the oil gas vavuum pump of enrichment is drawn into oil tank or liquefies with additive method; And the adsorbents such as active carbon are very little to the absorption affinity of air, not by the tail gas that adsorbs through emission by exhaust pipe.The method can reach higher treatment effeciency, and concentration of emission is low, but its complex process, the active carbon life-span is low, there is secondary pollution after inactivation, and adsorbent bed easily produces high temperature hotspot, there is the problems such as potential safety hazard.
Absorption process is the size according to the solubility of component each in mixed oil and gas in absorbent, carries out being separated of oil gas and air.General employing oil gas carries out counter current contacting with from absorbing the absorbent that tower top sprays, and absorbent carries out selective absorbing to hydrocarbon component, and unabsorbed gases discharges through spark arrester, and absorbent enters the desorb of Vacuum solutions cucurbitula, and enrichment oil gas absorbs with oil product again.The method technique is simple, and cost of investment is low, but the rate of recovery is too low, generally can only reach about 80%, cannot reach existing national standards; It is large that equipment takes up an area space.
Membrane separation process utilizes special polymeric membrane to have the feature of preferential permeability to hydro carbons, allow oil gas and air Mixture under the promotion of certain pressure, make oil gas molecule preferentially through polymeric membrane, constituent of air is then trapped discharge, and the oil gas of enrichment transmits oil return tank or liquefies with additive method.The shortcoming of the method is that membrane lifetime is short, expensive, and operation requirements is high, easily produces discharge layer, there is potential safety hazard.
Condensation method utilizes hydrocarbons vapour pressure difference at different temperatures, makes some hydrocarbon vapours pressures in oil gas reach supersaturation be condensed into the liquid method reclaiming oil gas by cooling.Can according to the minimum temperature of organic compound concentrations limit value determination condensing unit in the rate of recovery of the composition of Volatile Gas, requirement and the tail gas being finally discharged in air, the method technique is simple, and security is high, the rate of recovery is high, directly can obtain fluid oil, but complicated operation, and energy consumption is high.
