Abstract
Procedeul de sinteza a amoniacului, conform inventiei, este utilizat pentru recuperarea hidrogenului la sinteza amoniacului si refolosirea acestuia în procesul de sinteza a amoniacului, procedeu în care curentul de purjare este trecut într-un dispozitiv de separare continînd o membrana de separare, avînd o zona de alimentare si o zona de iesire a gazului separat prezentînd selectivitate la permeabilitatea hidrogenului, în comparatie cu permeabilitatea metanului, cît si a argonului, gazul penetrant recuperat în zona de iesire a gazului din membrana de separare fiind recirculat în zona de reactie, prin sinteza amoniacului, dispozitivul de separare cuprinzînd cel putin doua trepte de separare în serie, fiecare treapta de separare avbînd o zona de alimentare si o zona de iesire din dispozitivul de separare, zona de iesire din dispozitivul de separare aflîndu-se la o presiune totala mai mica decît presiunea totala în zona de alimentara între treptele de separare; gazul nepenetrant din zona de alimentare...
