liquid ring vacuum pump and vacuum compressor used in oil and gas recovery industry

Oil and gas recovery is energy efficient and environmentally friendly equipmemt with advanced technology , using oil and gas recovery system is used when oil emissions in the process of oil and gas storage and transportation, loading and unloading, prevent the air pollution caused by oil volatilization, eliminate safety hidden trouble, by raising the energy utilization, reduce the economic loss, resulting in significant benefits in return.The current common methods include adsorption method, absorption method, condensation method and membrane separation system, etc.

Liquid ring vacuum pump is widely used in oil and gas recovery industry not only can it prevent the air pollution caused by oil volatilization, eliminate safety hidden trouble, and by increasing the full use of energy, reduce the economic loss, so as to achieve significant economic results.

In order to ensure the safety of oil and gas recycling equipment running smoothly,  must be in strict accordance with the requirements of recovery technology is, earnestly implement the rules and regulations must be for the oil and gas recovery device before running the compressor, vacuum pump to carefully check to ensure that the main equipment, equipment in good condition, ensure the operation of the device is in the best, the most environmental protection.

This covers the use of the membrane separation

Membrane separation technology is relatively simple, low investment costs.Liquid ring compressor and membrane module is the core equipment of this technology.Compressor explosion-proof performance requirements is extremely high, but because of the explosion-proof technology mature, compressor safety hazard has been controlled to the lowest, can realize the safe operation.Membrane module, the other core equipment, after more than 20 years of development has been preliminary implementation localization, later the price is reasonable.

Membrane separation by using special polymer film on permeability characteristics of hydrocarbons have priority to oil and gas and air mixture under the impetus of the certain pressure, the oil and gas molecules priority through the polymer film, group is to intercept and air emissions, the enrichment of oil and gas transmission back to the LNG tank or by other methods,some time rotary vane vacuum pump also can used in the gas recovery system .

Advantages:
Advanced technology, technology is relatively simple;
Can intuitive see liquid recycle oil;
High safety;
High level automation

Weakness:

the steady flow, voltage stabilizing gas membrane separation device requirements.
