  • Patent number: 8920609
    Abstract: The device and method are provided to increase anhydrosugars yield during pyrolysis of biomass. This increase is achieved by injection of a liquid or gas into the vapor stream of any pyrolysis reactor prior to the reactor condensers. A second feature of our technology is the utilization of sonication, microwave excitation, or shear mixing of the biomass to increase the acid catalyst rate for demineralization or removal of hemicellulose prior to pyrolysis. The increased reactivity of these treatments reduces reaction time as well as the required amount of catalyst to less than half of that otherwise required. A fractional condensation system employed by our pyrolysis reactor is another feature of our technology. This system condenses bio-oil pyrolysis vapors to various desired fractions by differential temperature manipulation of individual condensers comprising a condenser chain.

    Abstract: The present invention relates to a method and system for regeneration of kinetic hydrate inhibitor when it is used without a thermodynamic inhibitor. In that the use of a distillation column or tower is not needed, the present invention enables a more compact system, which also improves the possibility for heat integration of the regeneration process leading to very low energy consumption. Additional improvements over the prior art include reduced cost of buying new chemicals, reduced environmental impact because the chemicals are not discharged with the produced water and the possibility for the use of higher concentrations of kinetic hydrate inhibitor with still reduced cost and environmental impact.

    Abstract: The invention relates to a vapor-compression method. The aim of the invention is to provide such a method respectively a system with which a distillation with a further reduced energy requirement is possible, which simultaneously operates reliably, with little maintenance, and with only little available power, in particular when starting, and which is able to handle fluctuations in the available power. This is achieved in that an aqueous solution is preheated and fed to an evaporator at a lower end in order to generate vapor. The vapor is conducted from an upper end of the evaporator to a compressor (V) in order to be compressed. The vapor that is compressed in the compressor (V) is used to supply energy to the evaporator. The vapor that is thus cooled or optionally at least partly condensed is used to preheat the aqueous solution.

  • Publication number: 20100147673
    Abstract: An improved water desalination system is disclosed, in which contaminated water such as seawater or brackish water is preheated and fed into a primary pressure vessel through a distribution head. The seawater is distributed from the distribution head over a non-adherent surface such as a plurality of silicone chords hanging below a distribution tank or a cone- and cylindrical-shaped surface. The water is exposed to a high temperature steam environment in the chamber to cause at least a portion of the water in the contaminated water to evaporate, while the remaining concentrated salts from the contaminated water fall to the bottom of the chamber. A portion of the steam in the primary pressure vessel is withdrawn to be condensed into fresh water. The energy withdrawn with the steam extracted from the primary pressure vessel is made up by a supplemental energy apparatus, such as a steam generator.

  • Patent number: 7563360
    Abstract: A top temperature T1 of a distillation tower 1 is held below a liquefying temperature of a light fraction by returning a part of an exhaust gas W, which is cooled by a condenser 5, to the upper zone of the distillation tower 1. A bottom temperature T2 is raised up to 300° C. at highest by returning a part of a liquid product P from a re-boiler 3 to a lower zone of the distillation tower 1. When a liquid hydrocarbon L comes in countercurrent contact with a stripping gas G inside the distillation tower 1 with the temperature profile that an inner temperature gradually falls down along an upward direction, mercury is efficiently transferred from the liquid L to a vapor phase without effusion of the light fraction in accompaniment with the exhaust gas W.

  • Publication number: 20080277261
    Abstract: A system for distilling sea or brackish water includes a feed water arrangement for supplying feed water from a feed water source to one or more flashing stages. Each flashing stage has a water flash evaporator for vaporizing at least part of the water therein, and a condenser for receiving the vapour and converting at least a part of the vapour into distilled water. A heat storage arrangement provided with a heat generating source for storing heat energy is used to heat a fluid medium flowing through it. A heat exchange arrangement receives the hot fluid medium and transfers heat to a stream of vapour flowing under pressure from each flashing stage. The vapour leaving the heat exchange arrangement being at a raised temperature is arranged to be condensed into water at the condenser and to transfer some of its latent heat to the evaporator.

  • Patent number: 6387221
    Abstract: Garbage and waste of all types that includes or comprises organic matter, particularly including medical waste, plastics, paper, food waste, animal by-products, and the like, can be economically recycled into petroleum products, including oil. Machinery performs a method that mimics natural processes but accomplishes the task in minutes, at rates of about 15 tons per day in a typical processing machine, rather than taking hundreds of thousands of years in nature. The process and apparatus of the invention may chop the waste into small pieces, under negative pressure if appropriate, and then pass the waste into first and then second augers for compression and heating. Destructive distillation occurs, in which large molecular weight hydrocarbons and petrochemicals are heated by hot oil passing through the hollow shaft and by circulating hot, dense, hard material, such as steel balls or fragments or hard rock pieces and such, under pressure with steam, to produce low molecular weight hydrocarbons.

    Abstract: An apparatus for reducing the coke dust in the decoking effluents of the hydrocarbon cracking ovens according to the invention provides means for the condensation of the effluent, means for collecting a liquid condensate, means for filtering said liquid condensate, and means for washing the residual vapours and gases that cannot be condensed by using the same condensate suitably filtered from coke, the filtered condensate being evaporated for the following discharge to the atmosphere by using the thermal content of the input decoking gases. A process for reducing the coke dust in the decoking effluents of the hydrocarbon cracking ovens according to the invention consists in that the solid content in the gaseous effluent from the decoking is removed by filtration of the condensate from said gaseous effluent and by washing of gases and vapours contained therein that cannot be condensed.

  • Patent number: 6149881
    Abstract: The amount of limonene produced during pyrolysis of scrap tire carcass or polyisoprene rubber can be increased by decreasing residence time of the isoprene gas produced during the thermal degradation of polyisoprene rubber in the high temperature reactor region of an oven. This is achieved by using a novel oven design which permits rapid expansion of the isoprene gas away from the high temperature reactor region of the oven to a cooler region where the gas forms limonene and condenses. This pyrolysis method also decreases the amount of soot produced while increasing the amount of limonene produced. Furthermore, this system readily enables separation of the solid, liquid and gas phases produced during pyrolysis.
