Abstract

1345198 Purifying coke oven gas and coal water CARL STILL 12 Nov 1971 [12 Nov 1970] 52664/71 Heading C5E Coal water (from tar distillation plants) 15 is treated at 14 with milk of lime 16 and steam 17 for heating to displace ammonia which is passed together with other gaseous products as a steam 18 to a separator 10. A wash liquid stream 9 arising from the washing of coke oven gas 1 in the towers 2 and 4 with a wash liquid 8 and containing ammonia is fed into the separator 10 in which ammonia is driven therefrom by contact with the hot gaseous stream 18. Ammonia leaves the separator 10 via a line 20 and the wash liquid 21 of reduced ammonia content is recycled to the tower 2 after cooling at 12 and 23. Streams 24 and 25 of wash water containing 0À2-0À6 g./l. ammonia can be removed from the tower 4.
