摘要： Nuclear magnetic resonance (NMR) relaxation and/or diffusion measurements are used to deduce fluid compositional information such as a chain-length distribution, which may then be used to predict the true boiling points (TBP) of a sample of a complex hydrocarbon fluid mixture, such as a crude oil. The NMR measurements may be considered a fast and portable proxy measurement in estimating fluid TBP distributions in lieu of distillation methods, or the simulated distillation by gas chromatography.

摘要： Systems and methods for monitoring a crude oil blending process use nuclear magnetic resonance (NMR) sensors which investigate properties of a plurality of crude oil streams that are mixed together to form a crude oil blend. An NMR sensor is also used to investigate the properties of the crude oil blend. The investigated properties may include viscosity. Resulting determinations may be used to control the input streams so that the output stream meets desired criteria. Additional sensors such as spectroscopy sensors, viscometers, and densitometers may be used in conjunction with the NMR sensors.

摘要： A mixing apparatus and method of mixing additives are described herein. The mixing apparatus comprises a mixing conduit having a wall, a first end, and a second end opposite the first end. A fluid inlet is formed in the wall between the first end and the second end. A fluid outlet is also formed in the wall between the first end and the second end. An injection conduit fluidly connects the fluid inlet with the fluid outlet. A pump is disposed to pump fluid in the injection conduit. An additive conduit is fluidly coupled to the injection conduit.
