Embodiment 1

[0044] Such as figure 1 , a storage tank VOCs safe collection method, comprising the following steps:

[0045] Steps for classified collection of VOCs in storage tank groups of various materials: VOCs discharged from storage tank groups 1A / B of various materials are classified and collected through oil and gas branch pipes 3 filling the roof of each storage tank.

[0046] VOCs connection processing steps for storage tanks of the same or similar materials: collect the VOCs discharged from multiple storage tanks 1A of the same or similar materials in multiple oil and gas branch pipes 3 collected by classification to the same or similar oil and gas tank group oil and gas collection pipe In 9A, the connection process is performed, and the VOCs discharged by the same or similar material storage tank group 1B in the multiple oil and gas branch pipes 3 collected by classification are collected into the oil and gas collection pipe 9B of the same or similar oil and gas tank group for c...

Embodiment 2

[0067] According to the method of embodiment 1, the difference is: the safe operation measures of the nitrogen blanketing group are not taken.

[0068] The method in Example 2 not only realizes the VOCs treatment of various material storage tanks, but also effectively reduces the emission of VOCs, and at the same time greatly reduces the risk of fire in the storage tanks and realizes remote cutting off the gas phase of the storage tanks in case of accidents.

Embodiment 3

[0070] According to the method of embodiment 1, the difference is: the fire-stopping measures of the air extraction equipment are not taken. The method in Example 1 not only realizes the VOCs treatment of various material storage tanks, but also effectively reduces the emission of VOCs, and at the same time reduces the risk of fire in the storage tank and realizes remote cutting off the gas phase of the storage tank in case of an accident. Easy maintenance.

Abstract

The invention relates to the technical field of safe collection of volatile organic compounds (VOCs) in normal pressure and low pressure storage tanks, and discloses a safe collection method for VOCsin storage tanks. The method comprises the steps of classified collection of the VOCs of storage tank groups of various materials, communication treatment of the VOCs of the storage tanks of the sameor similar materials, nitrogen sealing measure treatment for safety control of the storage tank groups of the various materials, emergency measure treatment, and discharging of the VOCs of the storagetank groups of the various materials. According to the method, not only is the fire risk of the storage tanks significantly reduced, but also the gas phase of the storage tanks can be remotely cut off in case of an accident so that the safety of the storage tanks can be guaranteed. Meanwhile, the method achieves the VOCs treatment of the various material storage tanks.

Description

technical field [0001] The invention relates to the technical field of safe collection of volatile organic compounds in normal pressure and low pressure storage tanks, in particular to a method for safe collection of VOCs in storage tanks. Background technique [0002] Odor gas emissions caused by the breathing of storage tanks, the volatilization of residual oil, the shutdown of cleaning lines, and the volatilization of solvents carried in oil have become a major source of air pollution in petroleum, petrochemical, and chemical companies. They are volatile organic compounds (VOCs ) is one of the main sources. As the country pays more and more attention to environmental protection, relevant regulations and standards are becoming increasingly strict. In order to meet the requirements of national laws and regulations, various refining and chemical companies have begun to implement large-scale VOCs collection and treatment projects in oil storage systems. [0003] At present, ...
