Abstract
A sample conditioning apparatus that removes moisture from a saturated gaseous sample and that utilizes the removed moisture for evaporative cooling within the apparatus is described. The sample conditioning apparatus includes a heat exchanger, a condensate drain trap, and a bypass line that directs a portion of the sample to a cooling medium inlet of the heat exchanger. The apparatus also includes a direction changing fitting to direct the condensate from the heat exchanger into a condensate drain trap. The direction changing fitting is coupled to a sample outlet of the heat exchanger and to the condensate drain trap. The direction changing fitting is also coupled to a membrane type moisture separator to prevent any liquid carrying over through to the gas analyzers. The moisture separator is also coupled to a first end of a bypass line, and to a sample line extending between the separator to the gas analyzers. The membrane moisture separator separates liquid moisture from the gaseous sample and directs the liquid into the bypass line. A portion of the gaseous sample is also directed through the membrane separator to the bypass line. Additionally, the condensate drain trap outlet is coupled to the bypass line.
