Abstract

Inventia se refera la un procedeu pentru concentrarea prin absorbtie a oxidului de etilena continut în gazul ce provine de la o instalatie de producere a oxidului de etilena gazul fiind mai întîi racit la temperaturi de 5....35 degree C se concentreaza prin absorbtie izoterma în pelicula de apa absorbtia realizîndu-se în doua trepte, la presiuni cuprinse între 1 si 30 at, presiunea în treapta a 2-a fiind mai mica decît cea din prima treapta si de preferinta 1,5 at.
