Minimising mist formation of flowing test gas - by relaxing pressure in cooled filter cavity with immediate absorption of evolved moisture

摘要

To prevent formation of mist and aerosols in gas being cooled before delivery to a treatment unit or analyser, the gas is fed into a hollow filter body inside the cooling unit. In the filter cavity the gas pressure drops, with evolution of aerosols and mist. With pressure and temp. at normal levels, these materials are absorbed by the filter material, with the gas then leaving the cooler towards the test unit. ADVANTAGE - Falsified results and/or damage to appts. are avoided without complex further equipment.
