Solvent Waste Recovery
Project number:
21081
Sponsor:
UA Department of Chemical and Environmental Engineering
Academic year:
2020-2021
Project Goal: Recover solvent waste from a polymer processing facility.
In polymer processing facilities, solvent waste contributes to profit and loss and environmental damage. A process to recover wasted solvents can mitigate financial loss and reduce environmental impact.
This design uses various separation techniques to recover solvent from plant waste streams. Flash distillation, column distillation and air scrubbing remove and separate waste stream components. Lash drums remove excess water to use for air scrubbing of vented solvents. After the excess water is removed, column distillation separates remaining components for plant reuse. Trace amounts of unrecovered solvent are sent to a bio pond for biodegradation.
Facility expansion can handle a wide range of flow and concentration fluctuations downstream from the polymer processing facility.
