Ọcha nke flue gas site na nkwusioru wayo
N'ihi na mmiri desulphurisation nke flue gas, ọ na-agafere ihe absorber (scrubber). Nkwusioru lime a na-enye n'ime ihe na-ekpo ọkụ (limestone ma ọ bụ mmiri ara ehi wayo) na-emeghachi omume na sọlfọ dioxide sitere na gas flue. Nke ka mma nnyefe uka, otú ahụ ka desulphurisation dị irè karị.
