COLD-CANDLE FILTER Russian patent published in 2003 - IPC

FIELD: devices for discharging toxic gases and cryogenic fluid vapors from process equipment into atmosphere. SUBSTANCE: cold-candle filter primarily designed to discharge combustible gases such methane, hydrogen, nitrogen, oxygen, ammonia, and the like into atmosphere has discharge tube with longitudinal ribs on its internal and external surfaces and with inlet pipe. Combustible gas used for the purpose is methane; ratio of external heat-transfer surface area F (area of external surface of discharge tube and external longitudinal ribs) to its flow section area S F/S = 4200...2000 at pressure of 0.1 2.) MPa, respectively, that is, at discharge pressure of 0.1 MPa F/S = 4200 and at 2.0 MPa F/S = 2000. EFFECT: enhanced mechanical and operating reliability of cold- candle filter. 15 cl, 2 dwg
