Title:
MULTIPASS TUBULAR HEAT EXCHANGER AND ASSOCIATED PASS PARTITION PLATE, CHANNEL COVER, AND METHODS
Document Type and Number:
WIPO Patent Application WO/2011/149617
Kind Code:
A3
Abstract:
A multipass tubular heat exchanger utilizing a pass partition plate and a tubesheet is described which is suitable for use with high differential pressure tubeside fluid without deformation or dislocation of the pass partition plate, thereby avoiding the problem of tubeside fluid bypassing. The pass partition plate has an edge fitting into a corresponding groove in the tubesheet. The edge and the corresponding groove each have a radius of curvature about an axis extending generally perpendicular to the tubesheet.
