What is the primary function of FGRU systems?

The primary function of FGRU (Flare Gas Recovery Units) systems is to compress gases for fuel gas systems. These systems are designed to capture and compress gas that would otherwise be flared (burned off) during oil and gas production and refining processes. By recovering flare gas, FGRUs not only help in managing waste gases but also improve overall efficiency by redirecting that gas back into the fuel gas system, where it can be reused. This contributes to reducing greenhouse gas emissions and enhances resource utilization within the refinery.

The other functions listed, such as producing heat for distillation, removing impurities from crude oil, and storing intermediate products, do not accurately describe the role of FGRU systems. Instead, each of those functions pertains to different operational aspects of refinery processes. For instance, heat production is more closely associated with heat exchangers, while the treatment of crude oil or intermediate products typically involves other specific units within a refinery.
