The fuel gas mixing drum is an integral part of many plants, especially LNG plants. Any change in fuel gas composition, properties or pressure can lead to operational problems in fuel-using systems, such as gas-fired turbines. These systems are designed to accept a certain degree of change of fuel gas properties; however, their burners are sensitive to the rate of this change. To limit this, fuel gas mixing drums are typically used. Fig. 1A shows a typical sketch of a fuel gas mixing drum. It consists of two separate sections, with a knockout drum (KOD) in the bottom section and a central riser pipe with a number of baffles in the top section. Fuel gas enters from the bottom section and flo
