Abstract
Systems and methods for inhibiting foam formation in an acid gas removal system are provided. Preconditioning a rich amine or triethylene glycol stream exiting an absorber of an acid gas removal system through a rotary separation turbine can provide pre-separation of gas from rich amine or triethylene glycol, as well as effectively reduces or inhibits foam formation. Systems provided enhance plant reliability and also recovers hydraulic power into electricity.
