Abstract

The invention discloses a multi-stage condensation, adsorption and cabin returning treatment capacity adjustable oil gas recovery device which comprises a precooling heat exchanger, a desulfurizing tower, a buffer tank, a multi-stage condensing unit, an adsorption device and an oil-water separation device, the multi-stage condensing unit comprises a first-stage refrigerating unit and a deep cooling unit, and the adsorption device comprises two adsorption tanks connected in parallel and a vacuum pump. The oil-water separation device comprises an oil-water separator and an oil storage tank, solves the problem of emission of high-concentration and large-treatment-capacity oil gas generated in transportation and wharf ship loading operation of crude oil, reduces the problem of huge economic loss caused by oil gas emission, and reduces the problem of environmental pollution of the ocean and areas around the wharf. And potential safety hazards caused by oil gas emission to production and life are reduced.

Description

technical field [0001] The invention belongs to the technical field of wharf and ship exhaust gas treatment, and in particular relates to an oil gas recovery device with adjustable processing capacity of multi-stage condensation + adsorption + return to cabin. Background technique [0002] The rapid development of ship oil cargo transportation has greatly met the needs of economic and social development, but it has also brought oil and gas volatile organic pollutants VOC and Volatile Organic Compounds to air pollution. In 1997, the International Maritime Organization approved the addition of rules for preventing air pollution from ships to the MARPOL73 / 78 MARPOL Convention, which came into effect in 2005; countries around the world have also adopted a series of countermeasures to prevent air pollution caused by oil and gas from ships. Since 1998, the governments of states along the coast of the United States have required tankers entering the port to use oil and gas recovery...
