Take the mystery out of running your LNG plant


While process simulation software can be used by plant engineers to calculate the dewpoint temperature of mixed refrigerant, this is of limited use to the plant operators at the control panel in maintaining an appropriate amount of mixed refrigerant superheat as they adjust the plant. To address these challenges, the authors’ company has developed a simplified method of calculating mixed refrigerant superheat that can be programmed in the distributed control system (DCS) and made available to panel operators.
