Abstract: Provided herein are methods and devices for determining water and sediment content in a hydrocarbon fluid sample. The methods and devices for determining water and sediment content in a hydrocarbon fluid sample include a Karl Fischer titration device and a titration vessel configured to implement a Karl Fischer titration and an ultrasonic particle detector configured to identify sediment in the hydrocarbon fluid sample.

Abstract: Black powder flowing with hydrocarbons in a hydrocarbon pipeline is converted into a magnetorheological slurry by implementing wet scrubbing in the hydrocarbon pipeline. A flow of the magnetorheological slurry through the hydrocarbon pipeline is controlled.

Abstract: A liquid sampling container with an internal mixer includes a sealed outer body configured to hold a sample multi-phase fluid obtained from a multi-phase fluid stream. An inlet line is attached to the outer body. The sample multi-phase fluid flows into the sealed outer body through the inlet line. A piston assembly is positioned within the sealed outer body. The piston assembly is sealed to the inner walls of the outer body to define a sample volume in which the sample multi-phase fluid is contained. A shear mixer is positioned within the sealed outer body. The shear mixer includes a rotor and a stator arranged to define a fluid passage and rotatable relative to each other. The rotor includes a rotary shear blade configured to shear the sample multi-phase fluid such that a homogeneity of multiple phases in the sample multi-phase fluid remains substantially constant.

Abstract: The invention provides a method for producing a homogenous sample of a pressurized fluid stream flowing in a pipeline, the fluid stream consisting of a majority component of hydrocarbon gas, the remainder consisting of one or more hydrocarbon liquids and water in the form of vapor, aerosols, droplets and/or liquid streams, the method includes the steps of: a. injecting one or more surface active agents into the fluid stream in an injection zone at a rate that is sufficient to form a uniform foam of the gas and the one or more hydrocarbon liquids and water components; b. mixing the one or more surface active agents with the fluid stream in a mixing zone to form a uniform foam composition flowing in the pipeline downstream of the mixing zone; c. withdrawing a portion of the foam composition from the pipeline at a sampling point; d. passing the portion of the foam composition withdrawn through a sampling loop; and e.
