    Abstract: An improved method of steam generation for thermal oil recovery by delivering the produced oil-water emulsion, together with a hot hydrocarbon liquid, to a flash vessel where most of the water is flashed off as steam, which can be used for injection in further thermal oil production; while the liquid phase, containing oil, entrained solids and some water is passed to a separator, where a portion of the oil is removed as sales product, most of the water and solids are removed as waste and the remaining oil and traces of water are recirculated to a heater and a flash vessel to provide heat for further processing. If desired, the produced water-oil emulsion may first be passed through a separator vessel which divides the emulsion into three streams, hydrocarbon liquid, gas and water; with hydrocarbon liquid being sent to a coalescer vessel to produce sales quality oil, the gases sent to a fuel or flare system and the water being treated as described above.

    Abstract: Provided is a method for performing thermal hydrolysis of sludge in a cyclic manner. A sludge stream is directed into one reactor during a first cycle and in a second cycle sludge is directed into another reactor. Each reactor has a sludge recirculation loop associated therewith. Flash steam from one reactor is transferred to the other reactor to pre-heat the sludge. The sludge in each reactor is recirculated through the circulation loop during each cycle of thermal hydrolysis. Live steam is directed into each reactor to raise the pressure and temperature within the reactor in order to enable the thermal hydrolysis process to take place.

  • Publication number: 20150090673
    Abstract: The invention relates to an apparatus and a method for purifying liquid. The apparatus comprises an air-tight container (301) and a heater (305). The air-tight container is configured to store the liquid, wherein at least a portion of the container consists of a filter membrane (303). The heater is configured to heat the liquid such that the liquid is driven out of the container through the filter membrane. The heater can actively increase the pressure in the container by heating the liquid and/or gas in the container. Sometimes, a portion of the liquid stored in the air-tight container may be vaporized, which increases the pressure in the container as well. Under the increased pressure, the liquid can be easily driven out of the container while being purified via the filter membrane. Since the filtration is actively driven by heating, the filtration efficiency of the apparatus can be controlled and improved according to various applications.

  • Patent number: 8869420
    Abstract: This invention presents a versatile and continuous drying technology that utilizes controlled heat combined with forced air supply for drying a feedstock. The dryer virtually divided top-down into different zones, each having definite heated air distribution rate to secure desired condition for drying of the feedstock. The heat source of the dryer is waste heat, either provided by the feedstock itself through exothermic heat generated by the feedstock or reclaimed waste heat or solar heat. The discharge system of the dryer is a fail-safe discharge system, which ensures equal residence time for the feedstock through all the zones.

  • Patent number: 8852436
    Abstract: A process for recovering solvents from inorganic and organic solutions is disclosed. The process utilizes a polymer capable of selectively extracting the solvent from the inorganic or organic solution. Introduction of the polymer into the solvent solution creates formation of a polymer-rich phase and a solute-rich phase. The recovered solvent may be separated from the polymer-rich phase by heating the polymer-rich phase to at least the cloud point of the polymer. The polymer and/or solute may be recycled for further use in the solvent recovery process.

  • Patent number: 8832962
    Abstract: The invention relates to a method for drying slurry-like materials, in particular sludge from wastewater treatment plants, including two drying stages, namely: a first indirect drying stage (2), supplied with hot fluid, which receives sludge having an entry dryness Se, and outputs sludge having an intermediate dryness Si and water steam, which is channelled towards a condenser (8) in which a heating fluid, in particular water, is reheated and, in turn, heats a heating gas for a second drying stage (6); and a step (5) of forming strings of sludge at the exit from the first stage; the second stage (6) of drying the strings of sludge using gas at least partially heated by the heat extracted from the condenser, said second stage outputting a slurry having a final dryness Sf; the intermediate dryness Si is controlled according to the measured entry dryness Se and the desired exit dryness Sf, for minimum consumption of the total energy used for drying, the flow rate, pressure and/or temperature of the hot fluid (3)

  • Publication number: 20140246386
    Abstract: In a method for the thermal separation of a volatile substance from a non- or less volatile substrate having a phase boundary towards a gas chamber that receives the volatile substance subsequent to vaporisation and/or sublimation, mechanical energy is supplied to the phase boundary between the substrate and the gas chamber to increase the material exchange of the volatile substance. In the method, the material exchange is increased by the addition of an additive or mechanical energy to the surface of the phase transition in such manner that said supplied mechanical energy destroys bubbles containing the volatile substrate, so that the volatile substrate can escape to the gas chamber.
