Abstract

The aim of this study is to simplify the process of discharge thermal energy combined desalination with power system by integrating the two existing heat exchangers (condensers) into a new multistream one. This system is a heat recovery unit, which is used to cogenerate water and power. Two shell-and-tube condensers operate in a closed power cycle and a desalination system for cooling an ammonia mixture as a working fluid and condensing a pure vapor, respectively. Here, a two-phase flow multistream condenser is utilized instead of the two low-eergy-efficiency shell-and-tube condensers. The results proved that the proposed technique leads to improving its exergy efficiency by 15%. The performance of the proposed condenser was analyzed by applying parametric optimization.
