Abstract: Embodiments of the present invention relate to a method and apparatus for mixing additives into a fluid fuel at a predictable concentration. The method comprises: taking a sample of the fuel; mixing the additive into the sample in metered proportions; testing the sample to determine that the correct amount of additive is present; storing the remaining fuel until it is time for the fuel to be used; and mixing the additive into the remainder of the fuel in the same metered proportions.

Abstract: The formation in a liquid hydrocarbon fuel of ice particles having a weight average particle size greater than 1 ?m when said liquid hydrocarbon fuel is cooled to temperatures in the range of from 0 to ?50° C. can be reduced or eliminated by use of at least one surfactant that is capable of dispersing water in said liquid hydrocarbon fuel to provide a stable clear water-in-oil microemulsion wherein the droplet size of the dispersed water phase is no greater than 0.25 ?m.
Abstract: An injection device is described herein, which is configured to atomize a liquid into droplets using a gas. The injection device has a body with walls defining a recess, a liquid inlet orifice being formed laterally in the walls, and a gas injection assembly in which there is formed a passage for the circulation of gas between a gas inlet orifice at one end of the recess and a gas outlet orifice situated inside the recess. The assembly defines, with the walls of the body, a space for the circulation of liquid from the liquid inlet orifice to the constriction. The walls of the body define a constriction having a throat, downstream of the gas outlet orifice, and the injection device is arranged in such a way that the stream of gas at the outlet orifice covers a wall portion in close proximity to the throat.
Abstract: A lubricant composition is provided containing an oil of lubricating viscosity and a substantially sulfur-free alkyl phosphate amine salt, where at least 30 mole percent of the phosphorus atoms are in an alkyl pyrophosphate salt structure, along with either or both of a conventional phosphorous containing antiwear additive and a glycerol ester. In the phosphate amine salt, at least 80 mole percent of the alkyl groups are typically secondary alkyl groups of 3 to 12 carbon atoms. A method of improving wear over a wide temperature range in a mechanical device is also provided by employing the lubricant composition.

Abstract: The process and apparatus enables purification of a recycle hydrogen gas stream from hydroprocessing biorenewable feedstocks. The recycle gas stream is fed to a methanator reactor to hydrogenate carbon monoxide in the gas stream to water and methane. Other acid gases can be removed by scrubbing preferably upstream of the methanator. Removal of carbon monoxide omits the need for a hydrogen purge stream to avoid carbon monoxide accumulation and enables use of the hydrogen for a downstream hydroisomerization reaction.
Abstract: The invention relates to approach temperatures and approach temperature ranges that are beneficial in operating a pyrolysis reactor, to pyrolysis reactors exhibiting a beneficial approach temperature, to processes for carrying out hydrocarbon pyrolysis in a pyrolysis reactor having a beneficial approach temperature. The pyrolysis reactor can be, e.g., a reverse-flow pyrolysis reactor, such as a regenerative reverse-flow pyrolysis reactor.
