Abstract:
A gravity pressure vessel (GPV) for processing a fluid stream containing organic materials provides several improvements to the art. In one embodiment, a GPV of the present invention sustains the heat energy requirements of a hydrolysis GPV by including therein, a first reaction chamber for conducting an exothermic reaction, and subsequently providing a second reaction chamber for hydrolysis of certain organic materials refractory to the exothermic reaction. Another embodiment provides for the perpetual cleaning of the heat transfer surfaces of the GPV. Still another embodiment provides for selective alteration of a hydrolysis reaction within a GPV independent of the flow of the fluid stream through the GPV.
Abstract:
A method for treating a waste stream, the method including the steps of providing a waste stream that includes waste solids suspended in water, feeding the waste stream to the top of a hydraulic downdraft column, conducting the waste stream to the bottom of the hydraulic downdraft column, conducting the waste steam to a first reaction zone, introducing nitrogen-containing oxides into the first reaction zone so that the waste stream is contacted with the nitrogen-containing oxides, conducting the waste stream up a hydraulic updraft column into a second reaction zone, where the second reaction zone is configured to provide sufficient time so that a reaction between the nitrogen-containing oxides and waste solids can take place and substantially consume the nitrogen-containing oxides, introducing oxygen gas into the waste steam after the nitrogen-containing oxides are substantially consumed, thereby providing a second reactant that reacts with waste solids suspended within the stream, conducting the stream to the top of the hydraulic updraft column.
Abstract:
Cellulosic material is converted to ethanol by hydrolyzing the cellulosic material in a gravity pressure vessel (50), and fermenting the product thereof. The gravity pressure vessel (50) employed is adapted to accommodate a continuous hydrolysis reaction and maximize the fermentable product yield on a commercial scale. The gravity pressure vessel (50) employed is also adapted to maximize the thermodynamic efficiencies of the hydrolysis reaction, as well as the entire ethanol producing process.

Abstract:
A method and apparatus for recovering energy from a wet oxidation products stream flow includes channeling the stream flow to an energy recovery assembly (10). The assembly (10) includes a rotatable reactor barrel (32). The reaction barrel (32) is mounted on an axle (33) for rotation therewith. The reaction barrel (32) has races (40) disposed in juxtaposition and circumferentially about the axle (33). Each race (40) is disk-like in shape, has an outer rim, and may be juxtapositioned adjacent to another race (40). The reactor barrel (32) is provided with a plurality of rocket nozzles (41) on each race (40), and rocket nozzles (41) on adjacent races (40) may be in staggered alignment with the rocket nozzles (41) of an adjacent race (40). The stream flow is channeled to and expelled through the rocket nozzles (41), thus causing the reactor barrel (32) to rotate. The stream flow may be channeled via nozzle ducts (52) having varying lengths to control the flow to the rocket nozzles (41). Rotational energy is transferred from the reactor (32) to a generator (43) Where electrical power is produced.
Abstract:
The continuous treatment of a liquid stream for removing a selected component therefrom, includes depressurizing the liquid stream to remove carbon dioxide, forming a carbon dioxide stream and a component-laden stream (17); raising the pH of the component-laden stream (17) to form a pH adjusted stream (19); gas-stripping the component-laden, pH adjusted stream (19) with a counterflow stripping gas (73) in a stripping column (20) having a plurality of deflection cones (111) over which the pH adjusted stream (19) is sprayed, to remove the component therefrom and thereby forming a relatively component-free liquid stream (50) and a gaseous component stream (21); cooling the carbon dioxide stream; neutralizing the liquid component stream (21) with the cooled carbon dioxide stream (64); cooling the gaseous component stream (21); re-heating the gaseous component stream to form a heated stream (35) and dissolving the heated gaseous component stream (35) in an acidic solution in a re-absorption column (36) forming a reduced gas stream (40) and a liquid salt complex stream (37) of the component; and utilizing the reduced component gas stream (40) to remove the component in the gas-stripping step.
Abstract:
A trash shredding device (10) includes an annular drum (41) which carries vertically spaced segmented blade members (47) in tracks (48) formed therein. A paddle (44) rotates within the drum (41) with its radially outer end (46) being adjacent to the blade members (47). Trash is introduced at one axial end of the paddle (44) and is forced against the blade members (47). The trash shredded by this action is discharged from the device (10) at the outer axial end of the paddle (44). The average overall sharpness of the blade members (47) is maintained by placing a new blade member (47) in the first of the tracks (48) while at the same time removing the oldest of the blade members (47) from the last of the tracks (48).
Abstract:
Disclosed are methods and apparatus for effecting a selected pattern of fluid flow wherein a first fluid is caused to flow along the surface of a body and a second fluid is caused to flow out of a plurality of holes in the surface of the body. The holes are arranged in a pattern so that the flow of the second fluid creates a baffle to change the direction of flow of the first fluid. The pattern is a grouping of holes wherein the grouping may be a straight line or a helix around a tubular body. The holes are rectangular in cross-section to form a fan-shaped pattern in the fluid passing through the holes. The longitudinal axis of each hole does not intersect the center of adjacent holes.
Abstract:
A continuously flowing fluid is processed by being fed to the top of a hydraulic downdraft column (17) which is of a height such that the pressure at the bottom thereof will approximately be at the pressure necessary to create supercritical water conditions. The fluid is conducted to the bottom of the column (17) and received in a reaction chamber (21) in which the majority of the fluid is recirculated around an annular baffle plate (24). The material in the reaction chamber (21) is heated to a temperature above that necessary to create supercritical water conditions by an independent reaction taking place in a heating chamber (32). The result is that the fluid will undergo chemical reactions at the supercritical temperature and pressure range and will be of a lower specific gravity than the unprocessed fluid. The material not being recirculated in the chamber (21) is fed to one of two updraft columns (30, 31), a start-up column (30) used to preheat the material in the downdraft column (17) during initiation of the process, and a second column ( 31) isolated from the downdraft column (17) so as not to transmit any heat thereto during normal operation of the process. The temperature of the fluid in the downdraft column (17) is thereby controlled to prevent decomposition of the material until the fluid enters the reaction chamber (21) at which time it is abruptly brought up to the supercritical water temperature.
