  • Patent number: 9896391
    Abstract: The invention relates to a process for preparing linear ?-olefins, wherein ethylene 1a is conducted into the oligomerization reactor 2 in the liquid phase. The oligomerization reactor 2 has a mechanical stirrer 2a in order to ensure optimal mixing of the liquid ethylene and of the catalyst in the liquid phase. From the top of the oligomerization reactor 2, vaporized ethylene is drawn off together with light ?-olefins and a small proportion of the organic solvent. The gas mixture drawn off from the top of the reactor 2 is condensed together with gaseous fresh ethylene 7 by means of heat exchanger 3 and separator 4. The liquid phase drawn off from the separator 4 is conducted by means of circulation pump 5a as liquid ethylene input 1a back into the oligomerization reactor 2. The liquid products of the oligomerization reaction are drawn off 8 laterally from the base of the reactor 2.

    Abstract: Disclosed herein is a fracturing unit for hydraulic fracturing having an engine and a fracturing pump connected to the engine through a variable speed torque converter. Also disclosed is a hydraulic fracturing system using multiple fracturing units which are sized similar to ISO containers. A hydraulic fracturing system may also force flow back water, produced water, or fresh water through a heat exchanger so that heat from the fracturing engines can be transferred to these liquids in order to vaporize them. A force cooled fractioning unit then can accept the vapor/steam in order to condense the various components and produce distilled water for re-use in the fracturing process or for release into the environment.

  • Patent number: 9834489
    Abstract: Provided is a method for producing bio-aromatic compounds from glycerol. The method uses a primary alcohol, secondary alcohol or a combination thereof as a mixing medium in converting glycerol into an aromatic compound, and thus overcomes the high viscosity of glycerol and improves the problem of rapid catalytic deactivation, thereby increasing the yield of aromatic compounds and improving the stability of catalyst. In addition, the method for producing bio-aromatic compounds uses a zeolite-based catalyst that is a kind of solid acid catalysts, and suggests optimum reaction conditions, and thus imparts a high added value to glycerol produced as a byproduct in a biodiesel production process and increases the cost-efficiency of process.
