Conforming to the factor characteristics of electricity–water cogeneration power plants, an improved multieffect desalination (MED) and reverse osmosis (RO) are the most current techniques for seawater desalination. A principal change between these operations consists of their various energy requirements, thermal energy for MED and mechanical energy for RO plants. The main improvement ideas of RO and MED are the recovery of large quantities of heat produced during the production of sulfuric acid, which exhibits an exothermic reaction where a part of this heat will be used for the thermal power plant and subsequently reverse osmosis and another amount of heat recovery system will be used to desalinate seawater by the MED system. In this work, the sulfuric acid is used to recover heat energy; this energy is used in a hybrid system of RO–MED in order to desalinate the seawater. A thermodynamic steady-state study of this system is investigated to select the optimum cogeneration system. These improvements could make the benefits of cogeneration to the energy consumption of an RO and MED which will be remarkably reduced.

使用RO和MED系统从硫酸厂回收海水淡化的热量

符合水电联产电厂的要素特征，改进的多效淡化（MED）和反渗透（RO）是最新的海水淡化技术。这些操作之间的主要变化包括它们的各种能量需求，MED的热能和RO工厂的机械能。RO和MED的主要改进思想是回收硫酸生产过程中产生的大量热量，这表现出放热反应，其中一部分热量将用于火力发电厂，并随后进行反渗透和另一部分MED系统将使用余热回收系统来淡化海水。在这项工作中，硫酸被用来回收热能。该能量用于RO–MED混合系统中，以淡化海水。研究了该系统的热力学稳态研究，以选择最佳的热电联产系统。这些改进可以使热电联产对RO和MED的能耗产生好处，这将大大减少。
