Abstract

Cooling water requirements of an oil refinery depend on processes in which the water is used for cooling and on complexity of cooling water network configuration.  

Most refineries still use networks of water coolers operating in parallel.  The result is that heated cooling water is collected to form one or several streams which are sent to cooling tower regardless of their temperature.  Authors analyze a recirculating cooling water system, taking into consideration only refinery processes for which data was available.

Using KSD (Kim & Smith Design) method, they synthesize an integrated water using network.  Their objective is to demonstrate that load of cooling tower and cost related to cooling water system can be reduced by modifying configuration of heat exchanger network.
