Abstract

The invention relates to a new process for the decrease in or a complete removal of the water content of heat-sensitive liquid materials such as melts or solutions containing at most 10% by mass of water, by evaporating them at a temperature of at most 30 DEG C higher than that of the melting point of the melt or the temperature of crystal precipitation from the solution. The process of the invention comprises carrying out the evaporation in a stripper tray column, through which a countercurrent gas is led at a rate between 25 cm sec<-1> and 110 cm sec<-1>.
