Abstract: An inlet particle separator system for a vehicle engine includes a separator assembly and a liquid injection system. The separator assembly defines an inlet flow path for receiving inlet air and includes a scavenge flow path and an engine flow path downstream of the inlet flow path. The separator assembly is configured to separate the inlet air into scavenge air and engine air such that the scavenge air is directed from the inlet flow path into the scavenge flow path and the engine air is directed from the inlet flow path into the engine flow path. The liquid injection system is coupled to the separator assembly and configured to introduce a diffused liquid into the inlet air flowing through the separator assembly.

Abstract: 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.

Abstract: A gas suction filtration apparatus in which a liquid filter medium is contained in a closed container. A gas intake pipe is positioned so as to introduce the gas to be filtered into the bottom of the container and a suction device applies a suction force to the upper part of the container to draw the gas through the liquid filter medium. Gas-liquid mixing plates are disposed in the container which have numerous holes for passage of the gas therethrough. The mixing plates have diameters only slightly smaller than that of the container, and preferably the gap between the outside diameter of the plates and the inside diameter of the container is smaller than the diameter of the holes so that substantially all of the gas to be filtered must pass through the holes to facilitate contact between the gas and the liquid filter medium.
