CONSIDER OPEN-RACK SEAWATER HEAT EXCHANGERS

摘要

HEAT EXCHANGERS that use seawater are common worldwide because they provide a compelling benefit - seawater is a free heat-transfer medium that doesn't produce emissions. The units exchange heat between a process fluid (cryogenic or hot) and seawater of ambient temperature. In warm sea conditions (i.e., water at >14°C or, better, >18°C), such a seawater stream can serve as the heat source in vaporizer/heater equipment. On the other hand, cold seawater (preferably <12°C) can handle cooling of hot process streams; even seawater in tropical climes might suffice to cool some process streams.
