The present invention is a device and a method that combines a carbon disulfide-releasing chemical with a low pH organic or inorganic acid to produce a carbon disulfide-containing fluid at or near the point of injection that minimizes or eliminates the possible exposure of carbon disulfide to workers and the environment. In one particular embodiment a positive displacement injection pump injects the carbon disulfide-containing fluid into a crude oil system for treating crude oil transmission lines and in downhole tubulars to remove paraffin deposits. The device uses a unique in-line motion mixer to mix two fluids. The device is electronically controlled locally and remotely with the system operating data displayed locally and transmitted remotely. The paraffin treating carbon disulfide-containing fluid and supplemental chemicals dissolve, disperse and remove paraffin deposits.

An apparatus for creating an emulsion, including: an inlet chamber; a channel comprising a length L, height H, an inlet and an outlet, and walls having surface energies, the channel inlet adjacent to the inlet chamber. The channel inlet walls have a first surface energy and the outlet walls have a second surface energy substantially different from the first surface energy. An outlet chamber is disposed adjacent to the channel outlet, the outlet chamber height H2 being greater than the channel height H.

Disclosed is a candle making apparatus including an electric appliance for a process of sequentially melting, mixing and holding the constituents of a container candle inside a jug and at a molten temperature until a user is ready to pour the melt into a container. Typically the constituents of such candles include vegetable wax, soy products, vegetable oils, fats or fatty acids. They are melted at a higher temperature, then mixed, and cooled so that volatile ingredients can be added at a lower temperature while the mixture remains melted, and is further stirred. The process is controlled by a microprocessor. A visual interface displays progress and accepts user input.

This application includes mixing devices, methods, and systems in which a second fluid can be introduced through a second flow channel to a dispersion member for extrusion through a perforated portion of a dispersion member into a first flow channel for mixing with a first fluid. In some of the present mixing devices, methods, and systems, the second flow channel is substantially perpendicular to the first flow channel, and/or the perforated portion is disposed on a downstream portion of the dispersion member.

The temperatures of fuel oils stored in fuel tanks 12a, 12b, 12c are separately detected by temperature sensors 52a, 52b, 52c, respectively. Based on the detection results, a CPU 49 heats a heat resistant fuel oil among the fuel oils using a heat exchanger 54, such that the temperature of an oil mixture generated by mixing the fuel oils satisfies a predetermined temperature condition. After the fuel oils including the heated heat resistant fuel oil are mixed in a blender 13, the CPU 49 detects the viscosity of the generated oil mixture using a viscometer 33. Thereafter, based on the detection result, the CPU 49 controls the mixture ratio or a heating temperature of the heat resistant fuel oil, such that the viscosity of the oil mixture satisfies a predetermined viscosity condition.

A method for forming superparticles, comprising: contacting a source dispersed phase, a sink dispersed phase, and a continuous phase, the source dispersed phase comprising a solvent and a plurality of particles dispersed within the solvent, the sink dispersed phase comprising a solvent, the solvent of the sink dispersed phase having a solubility in the continuous phase at a given temperature that is less than a solubility of the solvent of the source dispersed phase in the continuous phase at that given temperature, and the contacting being performed such that at least some solvent of the source dispersed phase migrates to the sink dispersed phase so as to give rise to a plurality of superparticles that comprise assembled particles of the source dispersed phase.

System for mixing a catalyst precursor into heavy oil using a high boiling hydrocarbon diluent to form a diluted precursor mixture, which is mixed with the heavy oil to form a conditioned feedstock, which is heated to decompose the precursor and form dispersed metal sulfide catalyst particles in situ. The high boiling hydrocarbon diluent is at a temperature above the decomposition temperature of the catalyst precursor and is first fed through a cooler and/or mixed with a cooler diluent to reduce its temperature and avoid premature decomposition of the catalyst precursor. The high boiling hydrocarbon diluent may include a portion of the heavy oil feedstock, a portion of the conditioned feedstock, a vacuum tower bottoms product, or other high boiling hydrocarbon material having a boiling point higher than 524 C. A portion of the diluent may optionally include a medium boiling hydrocarbon material having a boiling point less than 524 C.

System and method for mixing a catalyst precursor into heavy oil using a high boiling hydrocarbon diluent to form a diluted precursor mixture, which is mixed with the heavy oil feedstock to form a conditioned feedstock, which is subsequently heated to decompose the precursor and form dispersed metal sulfide catalyst particles in situ. Because the high boiling hydrocarbon diluent is typically at a temperature above the decomposition temperature of the catalyst precursor, it is first feed through a cooler to reduce its temperature to avoid premature decomposition of the catalyst precursor. The high boiling hydrocarbon diluent may include a portion of the heavy oil feedstock, a portion of the conditioned feedstock, a vacuum tower bottoms product, or other high boiling hydrocarbon material having a boiling point higher than 524 C. A portion of the diluent may optionally include a medium boiling hydrocarbon material having a boiling point less than 524 C.

Liquid suspensions are disclosed that include superabsorbent polymer suspended within a non-aqueous liquid. The liquid suspensions are capable of being pumped and sprayed onto waste fluids for clean-up procedures. The liquid suspensions can be made by high shear mixing of the superabsorbent polymer with the non-aqueous liquid until the superabsorbent polymer is suspended within the non-aqueous liquid.
