✦ Synopsis

Large vapor-compression units allow cogenerations of low power/water ratios including zero ratio whereby complete independence is achieved for the products of power and water. Mismatches in needs and load variations are avoided and more flexible planning for these two important commodities is permitted. A single-effect 2.5 mgd (11,000 t/d) vapor-compression system is theoretically analyzed with a conventional axial flow compressor and with an unconventional radial inflow compressor of a novel design. Basic features are computed and costperformance characteristics are evaluated. Although the results verify feasibility, experimental validation is essential. The economics of independent water production are discussed.
