Description
technical field [0001] The invention relates to the technical field of oil gas recovery and treatment, in particular to a passivation device of an adsorption oil gas recovery system. Background technique [0002] "Adsorption method" is one of the most basic and widely used techniques in oil and gas recovery. At present, the commonly used adsorption techniques include "adsorption + absorption" and "adsorption + condensation" techniques. The commonly used adsorbent in the "adsorption method" technology is activated carbon. Activated carbon has a large number of micropores that cannot be desorbed and regenerated. During its initial adsorption, a large amount of heat energy will be released and pose a safety hazard. Therefore, activated carbon must be "passivated" before use. deal with. "Passivation" is a common pretreatment method in activated carbon adsorption. It is to put activated carbon under the protection of inert gas to fully absorb passivation gas and release heat en...
