Problems solved by technology

[0002] With the development of economy and industry, the consumption of gasoline, diesel and other fuels is constantly increasing rapidly, and the fuel is highly volatile, and it is inevitable that oil and gas will be generated during the tank farm, tanker loading, unloading, and fuel use. Oil and gas treatment Improper chemical smog will be discharged into the atmosphere, endangering safe production and polluting the environment. At the same time, the discharge of oil and gas must meet the emission standards stipulated by the state, so oil and gas must be recovered
The traditional tank body used for oil and gas recovery adopts the bottom-in and top-out method, and the desorption gas enters the desorption tank from one inlet for desorption, but the desorption effect is not good when vacuuming and desorbing from one port, and the desorption time is relatively long , the desorption efficiency is low, and the use requirements cannot be met

Abstract

A new combined oil and gas recovery system and oil and gas recovery method, the oil and gas recovery system includes oil and gas adsorption / desorption module I, oil and gas adsorption / desorption module II, oil and gas inlet pipeline, desorption gas inlet pipeline, desorption oil and gas discharge pipe The oil and gas adsorption / desorption module I and the oil and gas adsorption / desorption module II have the same structure, including tanks, desorption inlets, desorption outlets, oil and gas inlets, and exhaust gas outlets; the oil and gas inlet pipelines It is equipped with a fan, a solenoid valve and an oil and gas concentration meter connected in sequence. The new combined oil and gas recovery method uses horizontally opposite desorption inlets and desorption outlets evenly distributed on the side of the tank body, so that the desorption airflow in the horizontal direction is evenly distributed, ensuring that the adsorbent is evenly heated and improving the desorption efficiency. The oil and gas adsorption / desorption module I, The oil and gas adsorption / desorption module II switches between the adsorption and desorption working modes under the action of the control module to realize continuous non-stop operation of oil and gas recovery.

Description

technical field [0001] The invention belongs to the technical field of oil and gas recovery, and in particular relates to a novel combined oil and gas recovery system and an oil and gas recovery method. Background technique [0002] With the development of economy and industry, the consumption of gasoline, diesel and other fuels is constantly increasing rapidly, and the fuel is highly volatile, and it is inevitable that oil and gas will be generated during the tank farm, tanker loading, unloading, and fuel use. Oil and gas treatment Improper chemical smog will be formed and discharged into the atmosphere, endangering safe production and polluting the environment. At the same time, the discharge of oil and gas must meet the emission standards stipulated by the state, so oil and gas must be recovered. The traditional tank body used for oil and gas recovery adopts the bottom-in and top-out method, and the desorption gas enters the desorption tank from one inlet for desorption, ...
