Sulfur contaminants, such as elemental sulfur (S8), hydrogen sulfide and other sulfur components in fluids (e.g., air, natural gas, and other gases, as well as water and other liquids) are removed using a silicone-based chemical filter/bath. In one embodiment, a silicone-based chemical filter includes a membrane having a cross-linked silicone that is a reaction product of an olefin and a polyhydrosiloxane. For example, sulfur contaminants in air may be removed by passing the air through the membrane before the air enters a data center or other facility housing computer systems. In another embodiment, a silicone-based chemical bath includes a housing having an inlet port, an outlet port, and a chamber containing a silicone oil. For example, sulfur contaminants in air may be removed by passing the air through the silicone oil in the chamber before the air enters a data center or other facility housing computer systems.
