Abstract

The invention provides a storage tank volatile organic compound recovery system. The storage tank volatile organic compound recovery system includes a first storage tank, a nitrogen sealed system, a second storage tank, a volatile organic compound collection system, and a volatile organic compound recovery system; the nitrogen sealed system includes a Y-shaped filter, a pressure gage and a self-actuated regulation valve; the volatile organic compound collection system includes pipeline flame arresters, automatic stop valves, and pressure transmission devices which are arranged on the tops of the first storage tank and the second storage tank, and an automatic stop valve positioned on a volatile organic compound collection pipe; and the volatile organic compound recovery system includes a third storage tank, an induced draft fan, a suction tower, pumps, adsorption towers, a vacuum pump and an anti-explosion flame-arrest ventilation cap. The storage tank volatile organic compound recovery system can recover crude oil and volatile organic compounds which are discharged by a product tank field in a non-organization manner.

Description

technical field [0001] The invention relates to the field of safe and environment-friendly storage and transportation of crude oil and products of petroleum refining enterprises, and more specifically relates to a storage tank volatile organic compound recovery system. Background technique [0002] Volatile organic compounds are all organic compounds (excluding methane) that have a vapor pressure greater than or equal to 10 Pa at 293.15K, or have corresponding volatility under specific applicable conditions. [0003] Volatile organic compounds include hydrocarbons, aromatic hydrocarbons, alcohols, aldehydes, ketones, lipids, amines, organic acids and other substances, which photochemically react with nitrogen oxides in the atmosphere under sunlight to generate ozone and excessive Photochemical smog such as oxynitroacyl and aldehydes cause secondary pollution, irritate human eyes and respiratory system, and endanger human health; most VOCs are toxic and have a foul smell, whi...
