Abstract
A forced-circulation evaporator plant for concentrating products such as liquid distillation residues and caustic soda has a circulating pump for circulating a product to be concentrated to a battery of heat exchangers interconnected in series. The last exchanger in the series is directly heated with steam. All of the other exchangers are heated by water vapors generated by the evaporation of the product to be concentrated in a battery of flash drums traversed in series by the product and by steam from hot condensate liquids coming from the same exchangers.
