MEHTOD FOR INHIBITING FOULING IN BASIC WASHING SYSTEMS

摘要

Fouling in basic washing systems such as caustic scrubbers can be prevented or at least mitigated by treating the liquid washing phase used in a caustic scrubber with an additive having at least one compound selected from the group consisting of oxalyl dihydrazide, a disulfite salt, isopropyl hydroxylamine, chlorobenzhydrazide, aminobenzhydrazide,, a thiosulfate salt, 4,4-dimethyl oxazolidine, a hydrosulfite salt, and mixtures thereof.
