1. A system for extracting and analyzing a wet gas sample from a pipeline, the system comprising:
a pipeline sample take-off probe; a take-off conduit connecting said takeoff probe to a sample conditioner to generate a vaporized wet gas sample, said sample conditioner including an electrically powered heater element, a pressure regulator, flow controller, and a conditioned vapor sample output; a vacuum jacketed insulated tubing defined by an outer tubular casing with an inner surface and an inner tubular vaporized wet gas sample conduit member an inner and outer surface, said inner tubular vaporized sample wet gas conduit member with a first and a second end where the first end is attached to said conditioned vapored wet gas sample output of said sample conditioner, said inner tubular vaporized wet gas sample conduit member being substantially coextensive with and coaxially disposed within said outer tubular casing and spaced therefrom so as maintain space between it and said inner surface of said outer tubular casing to form a thermal insulating annulus between said outer casing inner surface and said inner tubular vaporized wet gas sample conduit member outer surface, and said inner tubular vaporized wet gas sample conduit member defining a wall having a thickness sufficient to possess a pressure rating in excess of 500 psig (35 bar) and to allow for non-destructive bending, and said inner tubular vaporized wet gas sample conduit member having an inner diameter dimensioned to maintain sufficient pressure and flow rate to avoid flashing during transit threrethrough, and an electrically powered analyzer unit including a low power vapor analyzer for qualitative and quantitative detection of at least one analyte in said conditioned vaporized wet gas sample, said analyzer unit having an inlet in vapor communication with said second end of the tubular vaporized wet gas sample conduit member for receiving said conditioned vapor sample, an input for a carrier gas, said electrically powered analyzer detecting the at least one analyte of the vaporized wet gas sample and generating at least one signal corresponding to the obtained result; an electrically powered wireless communications module unit for transmitting the results to a remote receiver; a low power electrical control unit including a power control center electrically connected to each of the conditioner, analyzer unit and wireless communication module; and a photovoltaic panel with an electrical power storage array connected to the low power control unit for distribution to electrically-operated control unit. |
