Applications of double-effect climbing-film evaporator in glyphosate mother liquor concentration process was introduced. It is possible to sell the glyphosate solution in 10 % mass part from glyphosate solution in 4% mass part and mother liquid evaporation. By addition of liquid preheater approach, properly raising the steam pressure and improvimg,stablizimg vacuum, the production capacity of climbing-film evaporator is improved. Attentions in the operation and key points of the climbing-film evaporator operation are explained.
