  • Patent number: 11168339
    Abstract: Process and systems are provided for anaerobic digestion of lignocellulosic feedstock into biogas and co-products, such as fibrous humid cake and a fine-particles slurry. The feedstock (e.g., grass straw) is typically first ground or milled. The feedstock is subjected to pelletizing or extruding to generate pellets (e.g., cubes) or extrudates. The pellets or extrudates may be fed to a hydrolysis unit or a digester, in dry form or wet form. Various chemicals may be added to improve the mechanical disintegration of the lignocellulosic structure of the feedstock, before, during, or after formation of pellets or extrudates. The biogas may be stored, sold, used, or further treated, such as via purification to produce pipeline-quality cellulosic methane. The fibrous humid cake and the fine-solids slurry have many potential uses. Other potential co-products include lignin, biochar, energy (as heat and/or electricity), fertilizers, soil or land conditioners, ammonium sulfate, ammonium hydroxide, and carbon dioxide.

Because the elongated reactor vessel includes both a loading gate and an unloading gate that are arranged at opposite ends of the elongated reactor vessel, it is possible to remove consumed biomass, which is harmless in terms of epidemiologic hygiene and plant hygiene due to thermophilic process control during the fermentation, from the reactor vessel through the unloading gate and to transfer this consumed biomass directly to the composting process. The bioreactor thus has a “clean” unloading gate and an “unclean” loading gate.

  • Patent number: 8920658
    Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.

  • Publication number: 20140263060
    Abstract: Portions of a feed liquid are passed through respective condensers and liquid-liquid heat exchangers. The feed liquid is then heated and injected into a first feed-liquid containment chamber, where vapor from the feed is passed through a first gas-permeable membrane and directed into a first condenser, where the vapor is cooled by the feed liquid passing through the first condenser and condenses as it cools to produce a first liquid permeate. The first liquid permeate is passed through the first liquid-liquid heat exchanger where the first liquid permeate is cooled by the feed liquid passing therethrough. After the vapor is removed from the feed liquid in the first feed-liquid containment chamber, the remaining feed liquid from the first feed-liquid containment chamber is injected into a second feed-liquid containment chamber, where the process is repeated.

  • Publication number: 20140238917
    Abstract: An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gases. The constituent gases and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products.

  • Publication number: 20140217036
    Abstract: A reactor system including a main reactor having a reaction vessel in operative communication with a solar concentrator for focusing sunlight onto the reaction vessel for providing waste management and removal is disclosed. The sunlight focused on the reactor vessel provides ultraviolet radiation that degrades organic pollutants within the reaction vessel and infrared radiation boils off the liquid within the reaction vessel, thereby allowing a steady state condition to be achieved in the reactor vessel. The main reactor is in communication with a condenser that receives the water vapor and other gases from the reactor vessel in which a phase separation operation occurs such that heavier water liquid phase is captured within a storage chamber and the gaseous phase is transported to a gas scrubber for filtering the lighter gaseous phase.

  • Patent number: 8753487
    Abstract: An evaporation device has an inner tube and an outer tube. The inner tube is made of a hydrophilic membrane, such as DutyionT. The outer tube is preferably made of a material that readily absorbs solar radiation and is a good heat conductor. There is a gap between the inner tube and the outer tube for the flow of air. The inner tube contains a flow of impure water. The hydrophilic membrane allows water to pass to the outside of the inner tube as vapor, but prevents impurities from passing through. Air flowing in the gap takes up the water vapor and humidified air exits the evaporation device. This humidified air is subsequently cooled to collect the vapor and provide purified water, e.g. at a condenser.

Recovery of heat produced from an osmotically driven membrane process (ODMP) includes performing a draw solute thermal separation method on a first solution stream produced by the ODMP, in which the thermal separation method creates a first vapor stream containing draw solute from the first solution stream and a first liquid stream which is substantially free from the draw solute or which has a lower draw solute concentration than the first solution stream, and directing heat from at least a portion of the first vapor stream to a draw solute thermal separation method performed on a second solution stream from the ODMP.

  • Patent number: 8695813
    Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.
