Crude oil shipping oil and gas recycling method

Abstract

The invention aims at providing a crude oil shipping oil and gas recycling method which is applicable to crude oil shipping oil and gas recycling of large-size port wharfs so as to effectively treat environmental pollution caused by oil and gas emission of cabins during shipping to realize zero emission in wharf work, and is used for recycling and reutilizing original exhausted oil and gas to generate certain economic benefits. The crude oil shipping oil and gas recycling method comprises the following steps: connecting a gas conveying arm or a gas conveying hose of a ship and bank abutting joint system to a special oil and gas connector of an oil tanker, so as to lead out oil-and-gas-containing gas in the cabin of the oil tanker, wherein led-out oil and gas pass through an online monitoring system while being conveyed to an oil and gas recycling device; carrying out condensate removing treatment on the led-out oil-and-gas-containing gas in the cabin; and introducing the led-out oil-and-gas-containing gas to a desulfurization active carbon tank filled with desulfurization active carbon and carrying out desulfurization treatment on the oil and gas by virtue of the desulfurization active carbon.

Description

technical field [0001] The invention relates to a method for recovering oil gas from crude oil on board. Background technique [0002] The patent number is CN201310234691.7, and the invention title is "Oil Gas Recovery Method for Crude Oil Shipment", which discloses a method for recovery of oil gas from crude oil shipment, but it is found during use that the inert gas in the tanker cabin contains 10% carbon dioxide If the gas is desulfurized by wet lye, it will inevitably produce a large amount of sulfur-containing waste lye that is extremely difficult to handle, which will increase the operating cost and processing difficulty for the operation of the oil and gas recovery system. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a crude oil loading oil gas recovery process system suitable for large port wharves, to effectively deal with the environmental pollution caused by the oil and gas discharge ...
