Abstract
Inventia se refera la un procedeu de concentrare a solutiilor apoase de glicoli, conform inventiei, în scopul reducerii consumului de abur, acesta se supun evaporarii într-un evaporator multiplu, constituit dintr-o singura coloana verticala, divizata într-un numar de sectiuni cilindrice, la temperatura de 200...30 degree C si presiunea de 20...0,03 kgf/cm2, presiunea aburului saturat utilizat fiind de 2...4 kg/cm2.The invention relates to a process for concentrating the aqueous glycol solutions according to the invention in order to reduce the consumption of steam which is subjected to evaporation in a multiple evaporator consisting of a single vertical column divided into a number of cylindrical sections at a temperature of 200 ... 30 ° C and a pressure of 20 ... 0.03 kgf / cm 2, the saturated steam pressure being used being 2 ... 4 kg / cm 2.
