Flare Gas Recovery are Reducing and Monitoring Flare Gas

Flare Gas Recovery are Reducing and Monitoring Flare Gas What is Flare Gas? In Petroleum refineries, Natural gas processing plants and in Oil and gas Production sites, mixture of natural gases is generated from the below sources: Extraction of Natural Gas along with oil from oil wells, Gases formed above the liquid level in storage tanks, Flashing of high pressure crude to low pressures.

This gas consists of a mixture of various hydrocarbons and is also known as associated petroleum gas. The Gas is flammable in nature and its composition varies from plant to plant and will also vary with time over the operating life of the plant/Oil-well.

What is Gas Flaring and Why Flare Gas Recovery Systems are Useful?

Gas flaring is generated by the combustion of associated gas coming from industrial processes including oil and gas recovery and petrochemical production. It is one of the most significant contributors to the increase in greenhouse emissions. Flare Gas Recovery Systems are one of the cleanest solutions to minimize or eliminate gas flaring.

Ejectors in Flare gas Recovery systems Ejectors perform a central role in Flare Gas Recovery Systems [subsequently denoted by FGRS] by compressing the low pressure gas mixtures to working pressures. Ejectors utilize the available high pressure gas as an energy source to bring about this compression.

Recovering and Reusing Flare Gas An increasingly popular method is Flare Gas Recovery. Flare Gas Recovery is the process of recovering waste gases that would normally be flared. These gases are then used elsewhere in the facility, therefore reducing emissions and waste and consequently increasing efficiency.

The process involves capturing the gas from the flare knock-out vessel and compressing it using liquid ring compressors. The recovered gases can then be reused within the facility’s fuel gas system, as a refinery feedstock, or for re-injection.

Flare Gas Recovery can be used in any industry that uses flaring. These include refining, production, LNG, biogas and pharmaceutical.

Flare Gas being a combination of petroleum gases can be used as a source of Energy. An industrial survey has indicated that the amount of Gas burned in the Flare Stacks throughout the world in the year 2011 amounted to almost USD 29.8 billion.

Utilizing Flare gases helps the plant to cut down on its Energy costs and also create an in-house Fuel source.

Improper burning and incomplete burning leads to generation of toxic and harmful gaseous pollutants. The produced gases are known to create harmful and deadly effects on human life and the surrounding environment.

The Flaring of Flare gas is also a considerable source of carbon di-oxide emissions.

Hence utilizing flare gases can help an industry to reduce Energy costs, reduce its Carbon footprint and be responsible to the environment.

We at Crystal TCS Pvt. Ltd have taken a theory based approach towards establishing the Ejector performance estimation and have developed design from the basic principles of Thermodynamics and Fluid flow dynamics.

As stated above Flare Gas Recovery has to operate with a variable range of working conditions and compositions over their lifetime. We at Crystal TCS Pvt. Ltd have performed intensive research and development for coming with Ejectors in Flare Gas Recovery Systems.
