A system includes a first separator that separates water from a fluid material. The water settles on the bottom of the water knock-out tank. The system includes multiple compressors to boost the pressure of the fluid material. The system includes a second separator that separates condensate from the fluid material. The system includes a mixing pipe that mixes glycol with the fluid material and a first heat exchanger that cools the mixed fluid material and glycol. The system includes a third separator that separates gaseous components and liquid components of the mixed fluid material and glycol and a fourth separator that separates the liquid components of the mixed fluid material and glycol. The system includes a fractional distillation column that heats a first liquid from the fourth separator, gasifying a first portion of the first liquid. A second portion of the first liquid remains liquid and is natural gas liquids.

The invention relates to a method for the purification of lignin, cellulose and hemicellulose obtained from purines, which can be burned in compliance with environmental standards as a substitute for wood. The method of the invention produces a novel bio-fuel.

A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

The present invention concerns a process for producing biodiesel with bifunctional heterogeneous acidic catalysts from acidic raw materials, such as fatty acids and mixtures of fatty acids with triglycerides.

A real time additive processing system for crude oil or refined fuel products is coupled to a fuel transport line that transfers fuel from one storage tank to another storage tank. The fuel additive processing system includes a fuel additive storage tank coupled to a liquid conduit having a liquid pump with a speed/stroke controller that regulates the liquid pump. The liquid conduit is coupled to the fuel transport line at a fuel additive injection nozzle. The fuel additive processing system also includes a flow rate transmitter and a chemical or physical property analyzer coupled to the fuel transport line downstream of the additive injection nozzle. The fuel additive processing system includes a flow controller that communicates with the liquid pump speed/stroke controller, flow rate transmitter and chemical or physical property analyzer. A remote system allows selective control of the flow controller.

Implementations described and claimed herein provide systems and methods for processing liquefied natural gas (LNG). In one implementation, a solvent is injected into a feed of natural gas at a solvent injection point. A mixed feed is produced from a dispersal of the solvent into the feed of natural gas. The mixed feed contains heavy components. A chilled feed is produced by chilling the mixed feed. The chilled feed includes a vapor and a condensed liquid. The condensed liquid contains a fouling portion of the heavy components condensed by the solvent during chilling. The liquid containing the fouling portion of the heavy components is separated from the vapor. The vapor is directed into a feed chiller heat exchanger following separation of the liquid containing the fouling portion of the heavy components from the vapor, such that the vapor being directed into feed chiller heat exchanger is free of freezing components.

The present invention discloses a single stage energy efficient process for production of hydrogen enriched/mixed gas at low temperature. More particularly, the present invention discloses a single stage energy efficient process for production of hydrogen enriched compressed natural gas (CNG) or LPG or biogas at low temperature.

This invention is related to an additive composition comprising metal-based quantum clusters (QCs) dispersed in a hydrocarbon medium. The additive composition is useful as a fuel additive, as it acts as a combustion improver for liquid and gaseous fuels. The invention describes a process for the synthesis of the additive composition comprising metal-based materials in atomic cluster form in hydrocarbon dispersible medium. The stable liquid dispersion of the QC has been doped into the hydrocarbon fuels at required concentrations. The measurable flame temperature of the fuels, e.g., commercial LPG on burner has been observed to increase by at least 60-80° C. The flame with high heat through put can be used for efficient cooking, heating, annealing and other high thermal applications. The additive composition may also be used to improve the fuel economy of the liquid hydrocarbon fuels.
