Abstract (en)
[origin: EP0114110A2] Apparatus for removing ammonia or other alkaline diazo developer from copier @ gas, uses a packed column (5) through which the air passes, while acid solution as absorbing liquid is continuously @ in countercurrent until the acid solution in the reservor 21, 24 becomes exhausted, and is replaced. A multistage fan @oyed to drive the air against the back pressure processed by the packed column (5). The apparatus can treat the @ air from a high throughput copier and is surprisingly free from @ by salts evaporated from the absorber solution.
