Title: Stripping ammonia from liquors - by treating with lime in a stripping column and burning the spent lime sludge to regenerate it, for use with coke oven water
Inventor: HAESE EGON
IPC: C01C1/10
Filed: 1977-05-18
Abstract: Ammonia is expelled from ammonia-contg. solns. by treating the soln. with milk of lime in a stripping column, and driving the ammonia out with hot gas or vapours. The bottom prod., contg. the lime sludge, calcium sulphate, unused hydroxide, calcium carbonate and other Ca cpds., is removed from the stripping column and introduced into a separator. A pumpable slude is recovered from the separator and passed to a combustion chamber in which it is subjected to reducing combustion at 600-1200 degrees C, using combustion gas. The process is esp. useful for recovering ammonia from coke over waters. Combustion of the Ca-contg. sludge gives CaO which can be converted into Ca(OH)2 for reuse in the stripping column. This avoids the necessity for storing the Ca cpd. sludge, with consequent environmental pollution problems, as in prior art processes.
