Abstract

The invention discloses a system for recovering heavy hydrocarbon in VOCs in a storage tank. The system comprises an ejector, a heat exchanger and a micro-channel cyclone separator, a working fluid inlet of the ejector is connected with a fuel gas pipe of the heating furnace, and an ejection fluid inlet of the ejector is communicated with an upper gas cavity in the oil tank through an ejection pipe; a mixed fluid outlet of the ejector is connected with a heat source medium inlet of the heat exchanger; a heat source medium outlet of the heat exchanger is connected with a tangential inlet of the micro-channel cyclone separator; a cold source medium inlet of the heat exchanger is connected with a cold flow outlet of the vortex tube; a cold source medium outlet of the heat exchanger is connected with an inlet of the vortex tube; an inlet of the vortex tube is connected with a heating furnace fuel gas tube; and a liquid phase tangential outlet of the micro-channel cyclone separator is connected with a heavy hydrocarbon recovery pipeline, and a gas phase outlet of the micro-channel cyclone separator is connected with a fuel gas inlet of the heating furnace. A cold source in the heat exchanger is directly obtained by decomposing fuel gas of a heating furnace in a factory area through the vortex tube, and materials are convenient to obtain.

Description

technical field [0001] The invention belongs to the technical field of recovery of volatile organic compounds in storage tanks, and in particular relates to a recovery system for heavy hydrocarbons in VOCs in storage tanks. Background technique [0002] Oil depots, joint stations and other factory areas will set up a number of oil tanks for storing oil products. Among them, oil tank sending and receiving operations and static breathing are one of the important sources of volatile organic compounds (VOCs) in the factory area. Emissions are harmful to the atmosphere, environment and human health. As the country pays more and more attention to environmental protection, it is necessary to deal with the VOCs in the oil tank. [0003] Usually, most of the VOCs in the oil tank are extracted by an air extraction device, and then the extracted VOCs are directly introduced into thermal oxidation furnaces, thermal storage oxidation furnaces, heating furnaces and other open flame equip...
