A pressure exchanger transfers pressure energy from a high pressure fluid stream to a low pressure fluid stream. Many industrial processes operate at elevated pressures and have high pressure waste streams. One way of providing a high pressure fluid to such a process is to transfer the waste pressure to a low pressure stream using a pressure ...
Desalination is a process that removes mineral ... The pressure vessel acts as a countercurrent heat exchanger. ... Desalination stills control pressure, ...
Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages. [1]

The pressure in a space cannot be in equilibrium with the temperatures of the walls of both subspaces. It has an intermediate pressure. Then the pressure is too low or the temperature too high in the first subspace, and the water evaporates. In the second subspace, the pressure is too high or the temperature too low, and the vapor condenses.
Solar desalination is a desalination technique ... Each stage consists of a series of heat exchangers and flash chambers. ... water at a pressure of 0.1 atmospheres ...
The most significant difference compared to MED and MSF technologies is that there are no tube bundles heat exchangers within the pressure chambers. This permits enhancements [6] of the thermal distillation process: Treatment of high saline or heavily polluted waste water, even with precipitation of solids
