Abstract:
1. A method to qualitatively determine the content of a condensable polar component in a hydrocarbyl gas at a temperature from −12° C. to −8° C. and pressure from 4.1 kPa (600 psi) to 6.9 kPa (1000 psi) in a vessel or conduit, comprising contacting at least a portion of the gas with probe consisting of: (i) a steel housing having an inlet and an outlet for a gas, (ii) a high pressure coupling on said housing adapted to receive and cooperate with a probe consisting of: nickel, copper, silver, gold, ruthenium, rhodium and alloys thereof; and comparing the values to calibration data relating voltage current or both to polar component vapor concentration in the gas over predetermined pressures and temperature ranges.
