Selective Removal of H2S from Biogas by a Packed Silica

The removal of hydrogen sulfide from biogas by silica gel was systematically studied. The results indicate that H 2 S could be selectively and completely removed from the biogas until the silica gel became saturated. When it became saturated, the color of silica gel changed from blue to black. The used silica gel could easily be regenerated and

Barium sulfate

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO is a white crystalline solid that is odorless and insoluble in occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.

How Do I Remove Silica Deposits 2

What happens when silica is not removed from water? Silica causes etching, scratching, and spotting on glassware and other fixtures. Removal of silica is usually done as a means of preventing wear and damage to equipment. This is because silica can accumulate on surfaces and appear as hard mineral deposits known as scale.
