A known amount of marker may be added to a pressurized hydrocarbon fluid, or combined with an additive to form a mixture, and the mixture may be added to a pressurized hydrocarbon fluid. An amount of the marker in the hydrocarbon fluid may be determined. An amount of the additive in the hydrocarbon fluid may be determined based on the amount of the marker in the pressurized hydrocarbon fluid. An inline system may be used for detection of a marker in a pressurized hydrocarbon fluid. The system is fixed in a pressurized hydrocarbon fluid supply line such that pressurized hydrocarbon fluid flowing from a first location to a second location in the supply line passes through the detection system. The hydrocarbon fluid may be a liquid or a gas. The markers may include a variety of optical markers, such as fluorescent markers. Detection of the markers may include, for example, fluorescence detection.

Detection of markers in pressurized hydrocarbon fluids

This invention generally relates to a method and apparatus for direct detection of one or more markers in pressurized hydrocarbon fluids. The apparatus includes a vessel () and one or more valves (). The hydrocarbon fluid () may be a liquid or gas. Markers may include a variety of optical markers, such as fluorescent markers. The apparatus may be coupled to a hydrocarbon fluid source (), and the vessel () may be at least partially filled with hydrocarbon fluid from the hydrocarbon fluid source (). A&#x3e; detector () coupled to the vessel () may be used to detect at least one of the markers in the hydrocarbon fluid () while the apparatus is coupled to the hydrocarbon fluid source () and without the addition of reagents. Detection of markers may include, for example, fluorescence detection.
