How Entrained Gas Management Helps Improve Midstream Operations And Mitigate Leak Risks

Few applications are more stringent than custody transfer measurements on large midstream pipelines. Every small volume not accounted for and paid for can add up quickly. For this reason, many oil and gas companies rely on Coriolis meters for metering and mass balancing. Entrained gas in a liquid pipeline or liquid in a gas line is often a sign of a leak which is both costly and a potential health and safety risk. Two-phase flow can affect some Coriolis meters’ proper operation thereby altering their metering performance.  Since the meters effectively stop measuring in this condition, this can ultimately throw off results.

To combat this, some high-end Coriolis mass meters are now equipped with entrained gas management (EGM) technology to help the meter continue to track the mass flow and density while continually sending data to a comprehensive leak detection system (LDS) in spite of the challenging flowing condition. This mitigates the risks associated with two phase fluids while also helping detect leaks sooner and substantially reducing the number of false alarms.
