Embodiment 1

[0053] This embodiment provides a refinery oil gas recovery adsorbent activation and regeneration system, including:

[0054] Solvent tanker, said solvent tanker is filled with 20 tons of methyl tert-butyl methyl ether with a purity of 99%;

[0055] a solvent pump having an inlet connected to an outlet of said solvent tanker;

[0056] An adsorption tank whose inlet is connected to the outlet of the solvent pump. The adsorption tanks are two sets of adsorption tanks arranged in parallel, which are adsorption tower A and adsorption tower B respectively. The oil and gas recovery adsorbent to be activated and regenerated is filled in the adsorption tank, and the outlet of the adsorption tank is connected with the inlet of the solvent tanker;

[0057] A nitrogen pipeline connected to the inlet of the adsorption tank;

[0058] A vacuum pump connected to the outlet of the adsorption tank.

Embodiment 2

[0060] This embodiment provides a refinery oil gas recovery adsorbent activation and regeneration system similar to that of Embodiment 1, the only difference is that 20 tons of n-hexane with a purity of 99% is filled in the solvent tanker.

Embodiment 3

[0062] This embodiment provides a refinery oil gas recovery adsorbent activation and regeneration system similar to Embodiment 1, the only difference is that the solvent tanker is filled with 20 tons of cyclohexane with a purity of 99%.

Abstract

The invention provides a method for activation and regeneration of a refinery plant oil and gas recovery adsorbent. The method comprises a step A) of causing a solvent filling a solvent storage device to be pumped into an adsorption tank through a solvent pump, and causing the oil and gas recovery adsorbent to be activated and regenerated in the adsorption tank to be soaked in the solvent for 10 h or more, wherein the solvent is selected from one or more selected from a group consisting of methyl tert-butyl methyl ether, n-hexane, cyclohexane and light petrol; a step B) of using nitrogen to push out liquid contained in the adsorption tank from top to bottom after the solvent is released to the solvent storage device from the bottom of the adsorption tank after soaking, starting a resolution device to perform resolution, and obtaining the activated and regenerated oil and gas recovery adsorbent. According to the method for activation and regeneration of the oil and gas recovery adsorbent, one or more selected from a group consisting of methyl tert-butyl methyl ether, n-hexane, cyclohexane and light petrol serve as solvents to treat the refinery plant oil and gas recovery adsorbent, and the method is simple, has fewer steps and can be implemented under normal temperature and normal pressure conditions.

Description

technical field [0001] The invention belongs to the technical field of oil and gas recovery, in particular to a system and method for activating and regenerating an oil and gas recovery adsorbent in a refinery. Background technique [0002] Oil loading and unloading platforms and oil filling areas in the petrochemical industry are equipped with oil and gas recovery devices to recover the volatilized oil and gas during the oil loading process and oil storage process, reduce the emission of oil and gas into the atmosphere, reduce environmental pollution, and increase oil and gas production. Utilization value; The oil and gas recovery device is mainly an oil and gas adsorption-analysis process, and the oil and gas adsorbent used is mainly special-effect activated carbon. Activated carbon adsorbs oil and gas With the operation time of the device, the adsorption activity of activated carbon gradually decreases, the oil and gas adsorption rate gradually decreases, and the emission...
