FIELD: oil and gas industry.
SUBSTANCE: invention refers to fluid purification from volatile compounds, namely gas-air fluids, and can be used for removal of compounds, preferentially in municipal sewage system. A filter comprises a bowl placed over a purified air source. The bowl accommodates an exhaust pipe with its interior content isolated from a contaminated air and connected with the bowl volume. In-built absorbent cartridges surround an external surface of the exhaust pipe. The width of the cartridges makes 50-150 mm.
EFFECT: higher efficiency of removal of hydrogen sulphide, mercaptans, phenols.
