A high-efficiency oil and gas recovery adsorption tank regeneration device and regeneration method

Abstract

The invention discloses a high-efficiency oil and gas recovery adsorption tank regeneration device, comprising a liquid ring vacuum unit connected to the adsorption tank through pipelines, a Roots vacuum unit and a screw vacuum unit, the Roots vacuum unit and the screw vacuum unit are connected in series, and It is connected in parallel with the liquid ring vacuum unit; the outlet of the adsorption tank is provided with an analytic valve, the pipeline between the liquid ring vacuum unit and the adsorption tank is provided with a program-controlled valve one, and the connection between the Roots vacuum unit and the screw vacuum unit and the adsorption tank A program-controlled valve 2 is installed on the pipeline, and a heat exchanger is installed between the Roots vacuum unit and the screw vacuum unit, and its regeneration method is disclosed. It is applied to a large-capacity oil and gas recovery device, and the pumping capacity is the same and reaches the same level. In the case of the best pumping effect, the investment can be greatly reduced, and the gas ratio of the initial gas flow rate to the final gas flow rate can be reduced, making the entire regeneration process run more smoothly.

Description

Technical field [0001] The present invention relates to a high-efficiency oil and gas recovery adsorption canister regeneration device and a regenerative method, mainly used in a large treatment amount of the dock, refinery, and other oil and gas recovery apparatuses in the loading and unloading process of volatile substance. Background technique [0002] The vacuum pressure in the oil and gas recovery device affects the concentration of the exhaust gas, and affects the gas concentration concentration, and to a large extent, affect the size of the oil and gas recovery device, and the investment and operation cost of the entire device, but also affects almost entire. The operation of the device is stationary, so it is a very important operational parameter. [0003] In the prior art, the oil and gas recovery device is reused, and the regeneration method is a second-order vacuum manner that is combined with a simple liquid ring vacuum unit or a screw vacuum unit or a liquid ring va...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the oil and gas recovery devices are all reused, and their regeneration methods are all composed of a simple liquid ring vacuum unit or a screw vacuum unit or a two-stage vacuuming method composed of a liquid ring vacuum unit or a screw vacuum unit. The multi-stage composite vacuum pumping method is not very suitable for the recovery of large-capacity, multi-substance mixed gases
