ABSTRACT:
An integral coalescer filter-membrane device to provide clean sample gas to gas analyzers. The device includes a housing, an inlet port for feed gas, an outlet port to withdraw clean sample gas essentially free of entrained liquids, such as water, and particulate material which might contaminate or interfere with the gas analyzer, a bypass port and a drain port to remove by gravity coalesced liquid. The device includes a filter tube to coalesce and filter the feed gas stream and a chamber having a supported hydrophobic selected porosity membrane. The outlet port receives clean sample gas from the upper portions of the chamber, while the bypass port removes coalesced filtered gas from a lower chamber.
