Problems solved by technology

[0002] During the loading process of oil products, the oil gas produced by the volatilization of gasoline products escapes to the top of the tank car and is discharged into the atmosphere. The volatilized oil gas is flammable and explosive, with high concentration, and forms explosive gas with air and distributes in the tank In the upper space of the vehicle and around the exhaust port of the tanker, it is very easy to explode in case of an open flame, which will affect the safety of production

Embodiment 1

[0048] use figure 1 The entire structure and path layout of the same scale geometric similar miniaturization test was carried out in the laboratory, and the operation of the entire gasoline oil vapor recovery device was simulated by HYSYS. The absorbent is gasoline, and the adsorbent of the adsorption device 3 is silica gel and activated carbon. The silica gel is close to the inlet 31 relative to the activated carbon, and the activated carbon is close to the discharge port 32 relative to the silica gel. The vacuum pump 4 adopts a dry vacuum pump. The temperature of the gasoline used as the absorbent is controlled at 3 ° C. The temperature of the gasoline oil gas connected to the gasoline oil gas inlet 12 is 30° C. in summer.

[0049] The oil and gas recovery efficiency reaches 98%, and the emission concentration is 8-13g / m 3 about.

[0050] Among them, Appendix B of GB 20950-2007 Emission Standard of Air Pollutants for Oil Storage Depots for Oil and Gas Recovery Efficiency. ...

Embodiment 2

[0052] Except that the temperature of the gasoline as absorbent is controlled at 5 ℃, all the other are the same as embodiment 1.

[0053] The oil and gas recovery efficiency reaches 97%, and the emission concentration is 12-15g / m 3 about.

Abstract

The invention provides a gasoline gas recovery device which comprises an absorption tower, a coalescer, an adsorption device, a vacuum pump, a temperature monitoring device, an emission concentration detection device and a temperature adjusting device. The absorption tower is used for enabling an absorbent accessed through an absorbent inlet and gasoline gas accessed through a gasoline gas inlet to make countercurrent contact in the vertical direction so as to enable the absorbent to absorb gasoline in the gasoline gas. The coalescer is used for receiving gasoline gas treated by the absorbent of the absorption tower and further performing gas-liquid separation. The adsorption device is provided with an adsorbent used for carrying out gasoline adsorption on gas which moves from bottom to top and carries residual gasoline. The vacuum pump is used for performing vacuum regeneration on the adsorbent. The temperature adjusting device is in communication connection with the emission concentration detection device and the temperature monitoring device and is used for adjusting the temperature of the external absorbent. Three times of gasoline gas treatment are performed through the absorption tower, the coalescer and the adsorption device, so that the content of discharged gasoline-containing gas is reduced.

Description

technical field [0001] The present disclosure relates to the field of oil gas recovery, and more particularly relates to a gasoline oil gas recovery device. Background technique [0002] During the loading process of oil products, the oil gas produced by the volatilization of gasoline products escapes to the top of the tank car and is discharged into the atmosphere. The volatilized oil gas is flammable and explosive, with high concentration, and forms explosive gas with air and distributes in the tank The space above the vehicle and around the exhaust port of the tank vehicle are prone to explosion when exposed to open flames, which affects safe production. For this reason, it is necessary to recover the volatilized oil and gas. [0003] Although the volatilized oil gas has been equipped with an oil gas recovery device, the emission concentration of the gasoline-containing gas discharged after the treatment of the oil gas recovery device will be required to become lower and...
