Novel Agglomeration Strategy for Elemental Sulfur Produced during Biological Gas Desulfurization.

ABSTRACT: This article presents a novel crystal agglomeration strategy for elemental sulfur (S) produced during biological desulfurization (BD). A key element is the nucleophilic dissolution of S by sulfide (HS^-) to polysulfides (S _x ^2-), which was enhanced by a sulfide-rich, anoxic reactor. This study demonstrates that with enhanced S _x ^2- formation, crystal agglomerates are formed with a uniform size (14.7 ± 3.1 μm). In contrast, with minimal S _x ^2- formation, particle size fluctuates markedly (5.6 ± 5.9 μm) due to the presence of agglomerates and single crystals. Microscopic analysis showed that the uniformly sized agglomerates had an irregular structure, whereas the loose particles and agglomerates
