Title: Expulsion of fixed ammonia from gas liquors - using photometer to control amt. of side stream from hydrogen sulphide scrubber added
Inventor: DELLMANN WINFRIED
IPC: C01C1/10
Filed: 1977-07-30
Abstract: Expulsion of fixed ammonia involves passing the liquor from the ammonia scrubber into the NH2 degassing plant with a partial stream of the liquor from the H2S scrubber, the H2S scrubbing liquor cycle being supplied continuously with fresh NaOH or KOH soln., whilst satd. liquor is drawn off. The novel features are that 3.0-5.0 (3.5)% NaOH soln. is supplied to the H2S scrubber via a valve and the amt. of side stream of the wash liquor cycle is controlled by a photometer installed in the stream of liquor leaving the NH3 degasser so that all the fixed NH3 is decomposed. The economics of the process are improved.
