FLARE GAS RECOVERY SYSTEMS

FLARE GAS RECOVERY SYSTEMS

ZERO FLARING SYSTEM

Flare Gas Recovery system is one of the major environmental and energy conservation issue in Oil & Gas, Platparm Refinery and Chemical lndustry. These valuable Hydrocarbon vapours are efficiently recovered in our Flare Gas Recovery System using Liquid Ring Screw Compressor Systems. The key is to correctly engineer & design the system for the variable availability of feed. Recovering these value of Hydrocarbons are giving grate savings to the users in-terms of energy conservation and environmental benefits from the local authority. Clients will have great savings & environmental benefits by recovering those valuable Hydro Carbons.

Flare Gas Recovery Systems (FGRS) are specialized compression packages, which aim to recover and repurpose gasses and emissions, such as methane/LPGs and sulfur dioxide, that would normally be burned during the flaring process. Key to the safe operation of refineries and petrochemical facilities, the process involves capturing the gas from the flare knock-out vessel and compressing it using liquid ring compressors. The so-recovered gases can be reused within the facility’s fuel gas system, as a refinery feedstock or for re-injection.
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.

Natural gas that comes from oil wells is typically termed “associated gas” or “flare gas”. This gas can exist separate from oil in the formation (free gas) or it can be dissolved in the crude oil. Independent from the source of the natural gas, once separated from crude oil, it commonly exists in mixtures with other hydrocarbons such as ethane, propane, butane and pentanes. In addition, raw natural gas contains water vapor, hydrogen sulphide (H2S) and carbon dioxide (CO2), nitrogen (N2) and other compounds. Associated gas that contains impurities cannot be transported easily and also cannot be used without treatment until separated, or cleaned, by a GENERON® Membrane system used for flare gas recovery.

For a long time, oil producers have simply flared this unwanted oil by-product. But because of the increase in both environmental consciousness and energy demand, flaring is often avoided and is sometimes prohibited. Technically, several options exist for handling associated gas.

When petroleum crude oil is extracted and produced from oil wells, raw natural gas associated with the oil is brought to the surface as well. Especially in areas of the world lacking pipelines and other gas transportation infrastructure, vast amounts of such associated gas are commonly flared as waste or unusable gas. The flaring of associated gas may occur at the top of a vertical flare stack or it may occur in a ground-level flare in an earthen pit (as in the adjacent photo). Preferably, associated gas is reinjected into the reservoir, which saves it for future use while maintaining higher well pressure and crude oil producibility
