ABSTRACT:
This invention relates to a process for conducting ammonia in a diazo copying machine which comprises passing ammonia-containing exhaust air by first conduit means from a developing station of said copying machine through a cooled heat exchanger in which the ammonia and water is frozen out, then heating said heat exchanger to a temperature at which the water and the ammonia are liquified, passing the mixture of liquified water and liquified ammonia to a releasing station, adding fresh ammonia water to the liquified water and to the liquified ammonia, passing it together with the liquified water and liquified ammonia in the releasing station counter-currently to vapor produced by a vapor-generating means, and conducting the gaseous ammonia to the developing station, said process employing two heat exchangers, the first heat exchanger through which the exhaust air is passed being cooled and the second heat exchanger being heated for liquifying the ammonia and water frozen out during the preceding process step, whereby the second heat exchanger is cooled and the first heat exchanger is heated.
