2. The industrial process heat demand
From a number of studies on industrial heat-demands, several industrial sectors
have been identified with favourable conditions for the application of solar energy.
The most important industrial processes using heat at a mean temperature level are:
sterilising, pasteurising, drying, hydrolysing, distillation and evaporation, washing
and cleaning, and polymerisation. Some of the most important processes and the
range of the temperatures required for each are outlined in Table 1
