  • Patent number: 5433769
    Abstract: Disclosed is a process for removing emissions, originated in the manufacturing industry, especially from polymerization operations and thermoplastic polymer processing operations which includes collecting the air, containing the emissions, directing the air, containing the emissions through a first heat exchanger thereby cooling the air, directing the air, exiting the first heat exchanger, through a second heat exchanger, thereby cooling the air, directing the air exiting the second heat exchanger to a liquid removal system and directing the air, exiting the liquid removal system through the first heat exchanger, thereby heating the air.
