Efficient oil gas purification system

Abstract

The invention relates to the technical field of oil gas purification equipment, specifically to an efficient oil gas purification system. The system comprises an adsorption device, a stabilizer, a vacuum pump, a controller, a heat exchanger and a catalytic oxidation device, wherein the adsorption device is provided with a first air inlet pipe, a second air inlet pipe, a first air outlet pipe and asecond air outlet pipe; the adsorption device is communicated with an air inlet of the stabilizer through the first air outlet pipe; the second air outlet pipe is communicated with an air inlet of the vacuum pump; an air outlet of the vacuum pump is communicated with an air inlet of the stabilizer through a pipeline; the controller is installed on an air outlet of the stabilizer; an air outlet ofthe stabilizer is communicated with an air inlet of the heat exchanger through a pipeline; an air outlet of the heat exchanger is communicated with a low-temperature air inlet of the catalytic oxidation device through a pipeline; and a low-temperature air outlet of the catalytic oxidation device is communicated with an air inlet of the heat exchanger through a pipeline. The efficient oil gas purification system is high in purification efficiency, low in operation cost and simple in process.

Description

technical field [0001] The invention relates to the technical field of oil and gas purification equipment, in particular to an efficient oil and gas purification system. Background technique [0002] The large and small breathing of oil products or organic solvents during the storage process of loading and unloading trucks or storage tanks will cause the escape of oil gas or organic solvent waste gas, which not only leads to waste of oil products or organic solvent resources, but also causes environmental pollution. The emitted high-concentration oil gas or organic solvent waste gas continues to accumulate around, which will also increase the risk of combustion or even explosion. The Ministry of Environmental Protection requires the purification efficiency of organic waste gas to be ≥95%, and the requirements for the emission of benzene series are more stringent than before, which makes the treatment efficiency and emission The concentration cannot meet the requirements of ...
