Desalination using low grade heat in the process industry: challenges and perspectives.

摘要: Abstract This paper examines the use of low grade heat from process industries for thermal desalination processes as this is relevant not only to current energy conservation schemes but also may play a role in increasing capacity satisfy future water demands. The study focuses on sources mill located British coastal area which presents large quantity recoverable waste at temperature ( In first scenario, Humidification Dehumidification was identified suitable technology due its operating temperature. second upgraded using hybrid absorption pump and subsequently used feed Multiple Effect Distillation system. These two cases were compared terms performances economics. For both cases, payback period less than 10 years could be obtained price equal £2 per tonnes water. comparable home supply.
