ABSTRACT:
Methods and apparatus are provided for continuously detecting and monitoring the hydrocarbon dew point of a gas. A sample of the gas stream whose dew point is to be monitored is heated and/or cooled prior to detection by a dew point detector. The cooling of a first portion of a sample may be accomplished by a second portion of the sample which is removed prior to the dew point detector and allowed to expand to cool the first portion of the sample. The sample is normally cooled until the presence of condensate is detected in the gas by the dew point detector whereupon the sample gas is heated to above the dew point and the procedure of cooling and heating the gas stream occurs in a continuous manner.
