(119a) Enhanced Heat Transfer Technology Proves Beneficial In Cooling Water Driven Condensers

Cooling water driven condensers utilizing enhanced heat transfer technology deliver technical and economic advantages in both revamp and grassroots applications.  Meeting equipment performance demands within the confinement of an existing unit structure can be accomplished with simple tube bundle or in-kind exchanger replacements to debottleneck summertime limited condensers and improve operating profitability.  Energy savings resulting from lower column operating pressures have also been recognized.  In the design of new plants, reduction in the number of shell and tube exchangers presents initial capital savings, while reliable operation at close temperature approaches contributes to annual operating savings.  This paper will discuss several case histories of cooling water driven condensers utilizing High Cond^TM tubing, which have been successfully demonstrated in multiple operating plants around the world since 2008.
