Class Information
Number: 95/273
Name: Gas separation: processes > Filtering
Description: Process in which a gas and solid or liquid particles entrained therein are passed through a foraminous or porous mass which separates the solid or liquid particles from the gas by entrapment and retention while permitting the gaseous or vaporous constituents to pass through; and subcombinations of gas filtration processes that do not result in separation (e.g., cleaning of a filter, etc.) when the subcombinations are not provided for elsewhere.
