Abstract
Abstract A multi-effect distillation plant has its effects superimposed with the lowest pressure effect at the bottom and provision is made for raising the liquid through the effects via riser passages, using mainly the flashing energy to get lift. The flash steam so generated is condensed on the outer surfaces of the walls of the passages of the next effect. Within these walls the raised liquid is again gaining lift by being flashed to vapour at the lower pressure subsisting in the next effect. By this system both liquid and condensate acquires potential energy during distillation.
