Oil and gas mixture recycling method and device

Abstract

The invention discloses an oil and gas mixture recycling method and an oil and gas mixture recycling device. The device comprises a gas collecting pipeline used for collecting an oil and gas mixture, wherein an atomizer used for atomizing and spraying lean oil is arranged in the gas collecting pipeline; an outlet of the gas collecting pipeline is connected to a mixer; and an outlet of the mixer is connected to a gas and liquid separator. When the oil and gas mixture recycling device is used, the gas collecting pipeline collects crude oil and the oil and gas mixture diffused from a petroleum product; the atomizer atomizes the lean oil and sprays the atomized lean oil into the gas collecting pipeline; the atomized lean oil and the oil and gas mixture are mixed so that the oil and gas components are dissolved and absorbed; the mixture of the atomized lean oil and the oil and gas mixture is poured into a mixer so that the oil and gas mixture and the lean oil are further mixed, dissolved and absorbed to form rich oil and residual gas; the rich oil and the residual gas are subjected to gas and liquid separation in the gas and liquid separator; and the rich oil is recycled to be reused. Because the atomizer is directly arranged in the gas collecting pipeline to atomize and spray the lean oil and the lean oil is further dissolved and absorbed in the mixer, so the absorption area is greatly increased; the occupied area is small; the equipment is simple; the investment on the equipment is low; the production period is short; and the device has the advantages of low energy consumption, energy conservation and environmental friendliness at the same time.

Description

technical field

[0001] The invention relates to an oil-gas mixture recovery method and a recovery device, which are mainly used for recycling the oil-gas mixture produced in the process of gathering and transportation, refining, storage, transportation and sales of petroleum and its products. Background technique

[0002] Crude oil, gasoline and other light oil products (such as naphtha, benzene series, various light hydrocarbons, etc.) will inevitably volatilize a large amount of organic gases ( Hydrocarbon VOC S ). This kind of oil and gas evaporates in large quantities and is directly discharged into the outside atmosphere, which not only causes serious oil product quantity loss and quality decline, but also brings significant economic losses, and seriously pollutes the environment and leaves a major fire hazard. Therefore, the application of the recovery system for the above-mentioned oil-gas mixture in the process of oil loading and oil storage is particularly urgent....
