Abstract

Pentru uscarea gazelor naturale sau de rafinarie pana la un punct de roua de -30..-40grade C, foarte frecvent se foloseste procedeul de absorbtie a vaporilor de apa în dietilenglicol (DEG) sau trietilenglicol (TEG). Realizarea punctelor de roua sus-amintite necesota concentrarea (anhidrizarea) DEG si TEG pana la valori de 99,99% masa. Acest lucru nu se poate realiza prin fracsionare obisnuita. De aceea, s-a apelat la fractionarea azeotropa cu toluen conform procedeului DRIZO care, însa foloseste o temperatura în refirbatorul coloanei de anhidrizare peste temperatura de descompunere termica a DEG si TEG. Prezenta inventie elimina acest dezavantaj prin aceea ca în refierbatorul coloanei se injecteaza suplimentar o cantitate de n-heptan.
