✦ Synopsis

An analysis is made of the design and operating factors which lead to the great stability of operation and reliability of low-temperature horizontal tube vapour compression and multi-effect plants . These factors are stated, discussed, and an attempt is made to assess their relative contribution to process economics .

Recent reports on the state of the art of desalination technology have indicated the leading position of both low-temperature vapour compression and horizontal tube multi-effect distillation, on technical and economic grounds, for both single-and dual-purpose plants..

The practical experience of on-site performance of such plants has demonstrated the remarkable stability, flexibility and reliability of these processes in comparison with others .

It is shown that the basic concept of low-temperature operation (50-70°C) leads to a chain of interrelated consequences which have a profound effect on the design, economics, operation and maintenance of such plants, some of which can be evaluated in terms of plant and process economics .
