Abstract
Systems and process for volatile degradation removal from amine plant wash water are provided. The systems and processes include a separation device disposed within a water circulation loop and configured to continuously remove at least a portion of the volatile degradation products from the wash solutions. The separation device can be configured for stripping, distillation, and/or extraction of the volatile degradation products from at least a fraction of the spent wash water. Optionally, a chemical agent can be reacted with the volatile degradation products to form heat stable salts for subsequent removal.
