Vapor recovery system

Abstract

The invention discloses an oil and gas recovery system, comprising: an adsorption tank, which includes: a tank body, the bottom of which is provided with an air inlet pipe and an air outlet pipe I, and the top is provided with an air outlet pipe II; four horizontal plates are arranged at intervals in the middle of the tank body , the tank is divided into intake chamber, adsorption chamber Ⅰ, adsorption chamber Ⅱ, adsorption chamber Ⅲ, and gas outlet chamber in turn. There are multiple through holes Ⅰ on the horizontal plate, and the adsorption chamber Ⅰ, adsorption chamber Ⅱ, and adsorption chamber Ⅲ Both are filled with adsorbent; the upper end of the rotating rod is sealed and rotated to pass through the top of the tank body, and the lower end rotates through the two upper horizontal plates and is connected to the third horizontal plate in rotation. The rotating rod is driven by a motor to rotate. Rotary plate Ⅰ and rotary plate Ⅱ are set respectively, and through-holes Ⅱ are provided on the rotary plate Ⅰ and the rotary plate Ⅱ; multiple pulp plates are fixed on the rotary rod and located in the adsorption chamber Ⅲ, and there are multiple through-holes on the pulp plate. Hole III; condensing assembly. The invention has the beneficial effect of improving the adsorption efficiency of the adsorption tank.

Description

technical field [0001] The invention relates to the technical field of oil gas recovery. More specifically, the present invention relates to an oil vapor recovery system. Background technique [0002] During the loading process of oil tankers at the wharf, a large amount of oil and gas will be produced. Oil and gas are mainly hydrocarbons and sulfides, and the main component of hydrocarbons is CH 4 、C 2 h 6 、C 3 h 8 etc., are all flammable gases. If oil and gas are dispersed in the atmosphere, it will not only pollute the atmosphere, but also cause explosions easily when the temperature or pressure in the atmosphere is too high. The oil tanker and shore work have great potential safety hazards. Therefore, during the loading process of the oil tanker at the wharf, it is necessary to adopt necessary devices to recover oil and gas. At present, the oil and gas recovery system mostly adopts the method of adsorption and condensation, but the adsorption effect of the adsorpt...

AI Technical Summary

Problems solved by technology

Oil and gas are mainly hydrocarbons and sulfides, and the main component of hydrocarbons is CH 4 、C 2 h 6 、C 3 h 8 etc., are all flammable gases. If the oil and gas are dispersed in the atmosphere, not only will it pollute the atmosphere, but also when the temperature or pressure in the atmosphere is too high, the oil and gas will easily cause an explosion.

The oil tanker and shore work have great potential safety hazards. Therefore, during the loading process of the oil tanker at the wharf, it is necessary to adopt necessary devices to recover oil and gas.

At present, the oil and gas recovery system mostly adopts the method of adsorption and condensation, but the adsorption effect of the adsorption device is not ideal, which brings a greater load to the later condensation, and even the final exhaust gas cannot meet the domestic emission standards, let alone the more stringent ones. Foreign emission standards
