Oil gas recovery system

Abstract

The invention discloses an oil gas recovery system. The oil gas recovery system comprises an adsorption tank and condensation assemblies. The adsorption tank comprises: a tank body, wherein the bottomof the tank body is provided with a gas inlet pipe and a gas outlet pipe I, and the top of the tank body is provided with a gas outlet pipe II; four transverse plates, which are arranged in the middle portion of the tank body at intervals so as to sequentially divide the tank body into a gas inlet bin, an adsorption bin I, an adsorption bin II, an adsorption bin III and a gas outlet bin, whereina plurality of through holes I are formed in the transverse plates at intervals, and the adsorption bin I, the adsorption bin II and the adsorption bin III are filled with adsorbents; a rotating rod,wherein the upper end of the rotating rod rotationally penetrates out of the top of the tank body in a sealed mode, the lower end of the rotating rod rotationally penetrates through the two transverseplates located on the upper portion to realize rotational connection with the third transverse plate, the rotating rod is driven by a motor to rotate, the rotating rod is sleeved with a rotating plate I and a rotating plate II, and through holes II are formed in the rotating plate I and the rotating plate II; and a plurality of pulp plates, which are fixed on the rotating rod and located in the adsorption bin III, wherein a plurality of through holes III are formed in the pulp plates. The oil gas recovery system has the beneficial effect that the adsorption efficiency of the adsorption tank is improved.

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
