Application of Vacuum System in Oil and Gas Recovery
During the storage, loading, unloading, and transportation of oil products, a large amount of oil and gas will be generated due to its volatility. Therefore, in the above-mentioned process, the oil and gas recovery device is often equipped with a vacuum system to collect oil and gas. On the one hand, it can reduce oil and gas pollution and potential safety hazards, while at the same time, it can reduce oil loss and increase efficiency. Its technological process mainly includes collection and adsorption, desorption and desorption, and recovery.
In desorption and desorption, the vacuum system for oil and gas recovery is the core equipment in the process. After the adsorption tank is saturated, a high vacuum is required to separate the oil vapor from the adsorbent, which is also the regeneration process of the adsorption tank. Through the vapor recovery vacuum pump, the adsorption tank can reach a high vacuum state, and the adsorbed vapor can be desorbed from the adsorbent. After the pressure in the tank drops to a certain level, a small amount of nitrogen or air can be introduced into the adsorption tower as a cleaning gas to promote the further desorption of oil and gas. The oil and gas desorbed from the adsorbent can be sent to the recovery process as concentrated gasoline vapor containing almost no air.
The concentrated oil vapor desorbed by the vacuum system for oil and gas recovery needs to be convectively contacted with gasoline falling from the top of the absorption tower to the bottom of the absorption tower, and finally recovered as a liquid at the bottom of the absorption tower and sent to the oil storage tank.
The vacuum system for oil and gas recovery does not directly extract the oil and gas, but creates a high vacuum to realize the desorption and desorption of the oil and gas in the adsorbent, which is the manufacturing condition for recovery. The adsorption method of oil and gas recovery process can theoretically achieve infinitely low emission concentration, and at the same time, it has various operation modes and high efficiency. Therefore, it has become the most popular oil and gas recovery process in the world.
