A fuel pump for a liquid fuel water injection system of a motor vehicle is provided. The fuel pump includes a low-pressure pump that mixes water from a water tank of the motor vehicle with liquid fuel from a fuel tank of the motor vehicle to a liquid fuel water emulsion and provides the liquid fuel water emulsion at a low pressure. A high-pressure pump is in fluid communication with the low-pressure pump and compresses the liquid fuel water emulsion from the low pressure to a high pressure for injecting the liquid fuel water emulsion into an internal combustion engine of the motor vehicle via an injection rail of the motor vehicle. A pump drive drives the low-pressure pump and the high-pressure pump synchronously with a pump frequency independently from an engine speed of the internal combustion engine of the motor vehicle.

A process for blending a hydrocarbon-based composition that includes combining a first heated water stream with a first hydrocarbon-based composition comprising asphaltene to create a first combined feed stream and allowing the first heated water stream and the first hydrocarbon-based composition to interact such that the second combined feed stream comprises micelles and reverse micelles, thereby preventing asphaltene aggregation. The process further includes similarly combining a second heated water stream with a second hydrocarbon-based composition to form a second combined feed stream. The process further includes introducing the first combined feed stream and the second combined stream into a supercritical blending vessel operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water, and blending the first combined feed stream and the second combined stream to form a blended hydrocarbon-based composition.

A method of reducing the pressure of a liquid includes the steps of providing a conduit containing a packing material, such that a large number of small passages are formed in the packing material, and passing the liquid through the conduit and the packing material. The amount of packing material through which the liquid flows can be varied to vary the pressure drop experienced by the liquid passing through the packing material. The reduction in pressure achieved may be stepwise (discrete) or continuous. The method may be used to reduce the pressure of an aqueous polymer solution for use in a polymer flood technique for oil extraction, and allows the pressure to be reduced without damage to the polymer.
