Abstract
Prezenta inventie se refera la un procedeu pentru obtinerea acidului cianhidric dupa asa numitul procedeu BMA, procedeu ce consta în insuflarea, totala sau partiala, a amestecului de gaze format din amoniac si hidrocarburi alifatice cu catena scurta, de preferinta metan, printr-un tub de introducere prevazut cu unul sau mai multe orificii, dispus în tubul de reactie, la o presiune preliminare de cel putin 1,2 bar, amestecul gazos fiind lasat sa curga cu o viteza de peste circa 200m/s din orificiile tubului, dupa care gazele produse sunt prelucrate în mod obisnuit. Drept hidrocarburi ce pot fi luate în consideratie, în afara de metan, ca hidrocarburi alifatice cu 3 si 4 atomi de carbon, sunt gazele lichefiate propan, n-butan si i-butan, la utilizarea acestor gaze lichefiate trebuind sa fie prezent si hidrogenul, si anume, într-un raport atomic C:N:H de 1:1:7,1 pîna la 1:1,33:12. în prezent, la scara industriala se utilizeaza, în special, metan, care se foloseste atît în stare pura, cît si sub forma obisnuita, de exemplu ca gaz de pamînt sau gaz de rafinarie. în cazul utilizarii gazului de pamînt si a gazului de rafinarie, se prefera gazele cu un continut total de metan de 60 pîna aproape de 100% în volume, care contin doar mici cantitati de hidrocarburi superioare...
