Problems solved by technology

Membrane separation method, using special polymer membranes that have preferential permeability to hydrocarbons, so that the mixture of oil, gas and air is driven by a certain pressure, so that the oil and gas molecules preferentially pass through the polymer membrane, while the air components are trapped Emission, the enriched oil and gas are transported back to the oil tank or liquefied by other methods. Although the above oil and gas recovery technologies can be used for organic waste gas treatment, the treatment effect still needs to be improved. Now a kind of oil and gas recovery and waste gas treatment is proposed. system

Abstract

The invention provides an oil gas recovery and exhaust gas treatment system which comprises an oil storage tank, a back-fire relief valve, a switching valve, a pressure sensor, a first vacuum pump, asecond vacuum pump, a recovery oil tank, an oil return pump, a low-temperature circulating water condenser, a first adsorption tank, a second adsorption tank, a third adsorption tank, a fourth adsorption tank, an adsorption fan, a catalytic incinerator, first gas chromatography with FID, second gas chromatography with FID, third gas chromatography with FID, fourth gas chromatography with FID, fifth gas chromatography with FID and sixth gas chromatography with FID and a filling region. Concentration of gas in the oil tank is judged by monitoring the pressure online, logic valves are controlled,oil gas in the oil tank is conveyed to condensed recovery gas through a pipeline, most of oil gas is liquefied by way of pressurizing by the vacuum pumps, a small amount of gas which cannot be liquefied enters an activated carbon adsorption system, and is enriched and enters a condensing system to be recovered through vacuum adsorption, so that the optimum treatment effect can be achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of oil and gas recovery, in particular to an oil and gas recovery and waste gas treatment system. 【Background technique】 [0002] Existing oil and gas recovery technologies include common methods such as adsorption, absorption, condensation and membrane separation systems. The adsorption method utilizes the adsorption force of the adsorbents such as activated carbon, silica gel or active fiber to the oil / air mixture to realize the separation of oil / gas and air. It has high treatment efficiency and low emission concentration, which can reach very low values. The absorption method separates oil and gas from air according to the solubility of each component in the mixed oil and gas in the absorbent. The process is simple and the investment cost is low. The direct conversion of phase to liquid phase. The process principle is simple and the economic benefits are the most impressive. Direct combustion method ...
