Abstract
Inventia se refera la un procedeu criogenic e îndepartare fractionata a gazelor acide din amestecuri gazoase din gaze naturale sau de sinteza, cu continuturi ridicate de H2S si CO2 prin absorbtie din solventi, alesi dintre esteri de alcooli sau de glicoli, lactone, dieteri, manoeteri, esteri-eteri, acestia putînd fi utilizati, singuri sau în amestec cu apa si/sau un compus organic, avînd un punct de topire scazut, procedeu caracterizat prin aceea ca, în scopul obtinerii uni grad înalt de puritate a gazului natural sau de sinteza, printr-o tehnologie simpla si accesibila, se introduce gazul natural sau de sinteza într-o prima coloan de absorbtie pentru desulfurare, care functioeaza sub presiune de 35...80 at si la o temperatura de -30...+20 degree C, gazul purificat complet de H2S, scindat, eventual, în doua sau mai multe fractiuni, prin condensare fractionata putînd ,fi destinat într-o turbina, este alimentat apoi într-o coloana de distilare pentru reducerea continutului e CO2, presiunea din coloana de distilare pentru reducerea continutului de CO2, presiunea din cloana fiind de 30...75 at, avînd temperatura de vîrf de -57...-30 degree C, iar la baza de -70....+31 degree C, dupa care gazul evacuat din colana de distilare este introdus într-o a doua coloana de absorbtie sub aceasi presiune si la temepartura de -100...-10 degree C, se regenereaza solventul sau solventii folositi în 2-6 trepte de destindere, ultima treapta lucrînd sub o presiune de 0,2...2 at, compusii utili recirculîndu-se ..............
