Abstract

The invention relates to the use of a composition comprising a) 3,3′-methylenebis(5-methyl oxazolidine) and b) one or more additives selected from among (i) urea, urea derivatives, amino acids, guanidine and guanidine derivatives and (ii) 1,2-diols in the removal of sulphur compounds from process streams. The composition is preferably used in the removal of hydrogen sulphide from process streams.
