Description
Technical Field
The invention relates to the technical field of environmental protection and energy conservation, in particular to a method and a system for reducing emission of waste gas discharged by a storage tank.
Background
During storage and transportation of oil and chemicals, large amounts of oil and gas or Volatile Organic Compounds (VOCs) are lost. According to statistics, the oil loss caused by the loss of light oil products accounts for about 0.5 percent of the light oil products each year, on one hand, a large amount of oil gas or volatile organic compounds are wasted, the economic benefit of enterprises is reduced, and on the other hand, serious environmental pollution is caused. In addition, as the oil gas and the air are easy to form an explosive mixture (the lower explosion limit is generally 1% -6%), the oil gas dissipation can cause the concentration of the oil gas around corresponding facilities to easily reach the explosion limit, and the oil gas gathered on the ground brings great potential safety hazards to enterprises and consumers, thereby endangering the safety production of the enterprises and directly influencing the health of operators and surrounding environment personnel. Therefore, it is necessary to recover the dissipated oil gas.
The traditional oil gas recovery treatment mode has three kinds: firstly, the fuel is directly used as fuel; oil gas is returned to the oil tank gas-liquid balance system, so that the oil gas partial pressure is increased, and the evaporation loss of oil products is reduced; thirdly, recovery devices and technologies are adopted, such as a condensation method, an absorption method, an adsorption method, a combined process thereof and the like.
CN101342427A discloses a method for recovering oil gas by a condensation-adsorption combined process, wherein, the oil gas is cooled and condensed to realize the condensation and separation of part of oil gas components, the uncondensed oil gas is recovered by adsorption-pressure swing desorption, the adsorbed tail gas reaches the standard and is discharged, and the desorbed oil gas returns to a cooling device to be mixed with the collected oil gas and enters a condenser. The recommended oil gas condensation temperature is-80-30 ℃, and the optimal temperature is-70-40 ℃. Oil gas components are recovered mainly by means of condensation and liquefaction, the condensation temperature is low, crystallization occurs in a condenser, and crystallization and condensation oil of water need to be removed periodically, so that two series of condensers are required to be switched for use; the total energy consumption of the device is larger, and the failure rate of the refrigeration equipment is higher. In addition, crystallization also occurs in the subsequent adsorption tanks, significantly reducing the service life of the adsorbent.
CN 105737517A discloses an oil storage tank exhaust gas purification method and device, and in this patent the oil storage tank exhaust gas is through compression condensation with heavy component oil gas condensation recovery in the exhaust gas, and noncondensable gas returns low pressure gas pipe network, has realized that the oil storage tank is when normal operation, and no pollutant is arranged outward, has avoided the discharge of tank field atmospheric pollutants. CN108069155A discloses a storage tank discharge gas emission reduction and recovery system, and in this patent, the oil storage space of the storage tank is strictly separated from the air space by using a floating disc, an edge seal, a seal film and a fixed ring plate, and the oil product is closely separated from the air, so that the oil gas generated by the evaporation of the oil product is pure oil gas, the gas itself has no explosiveness, and the evaporated oil gas can be safely controlled and recovered. Meanwhile, the floating disc is contacted with the oil product, so that the evaporation space of the oil product is reduced, and the loss of the oil product is reduced to the maximum extent. The oil gas evaporated by the storage tank can enter a low-pressure gas system after being subjected to desulfurization treatment by the absorption tower, so that no pollutant is discharged from the storage tank. However, in the methods disclosed in patent CN 105737517A and patent CN108069155A, an oil gas recovery system needs to be arranged and communicated with a gas pipe network, the system is complex, and the device investment is high.
