Abstract:

Abstract:
A containment casing (10) for a deep well/gravity pressure reactor vessel includes a plurality of casing sections (11) each having a wall portion (20) with corrugations (21). An inner liner (24) and an exterior liner (25) prevent grout material (13) from entering the corrugations (21) during installation. Additionally, inner liner (24) is capable of supporting the hanging weight of the casing sections (11), and yet is susceptible to failure due to stresses induced by thermal fluctuations. The corrugations (21) allow for thermal expansion without a buildup of compression stresses and further allow for angular deviations of the casing (10).
Abstract:
A method for separating dissolved materials, including organic and inorganic solids and volatile constituents, from a liquid or aqueous solvent is disclosed. The method first extracts water from the flow stream being treated using a crystallization apparatus which freezes the water onto a continuous loop wire rope and withdraws the wire rope from the chamber containing the feed stream. The resultant concentrated solution is then subjected to a different process of evaporation by heating at reduced pressures resulting in the efficient separation of the materials in solution from the liquid medium while conserving energy. This procedure is considered highly effective in allowing for the concentration of the materials and then the extraction of the materials in solution and the recycling and reuse of the water or other liquid.
Abstract:
A device for cleaning opposing surfaces (13, 14) of concentric columns (11, 12) is formed from a strip of material (20) configured as a spiral having inside and outside edges (21, 22) such that each edge (21, 22) forms a helix. The device (10) is utilized by introducing it between the concentric columns (11, 12). The strip (20) inside edge (21) abuts the opposing surface (13) of the inner column (11), and the outside edge (22) abuts the opposing surface (23) of the outside column (12). The device (10) is forced to travel along the lengths of the columns (11, 12) by an hydraulic fluid downflow thereby scraping deposits from the opposing surfaces (13, 14).
Abstract:
A fluid is continously processed by being fed to the top of a hydraulic downdraft tube (15) which forms a downdraft column which is of a height such that the pressure at the bottom thereof will approximately be at the pressure necessary to dissolve sufficient oxygen in water to control the surgical oxidation of lignite in paper pulp in concert with proper retention time and predetermined temperature high and low limits. The fluid is conducted to the bottom of the tube (15) and treated in a variable depth reaction zone (25) in which turbulence is introduced with an injected mixture of reactant and non-reactant gases. The result is that lignite in the pulp will be bleached releasing a controlled proportion of heat to the fluid which enhances the reaction. The treated fluid is fed into an updraft annulus (26) wherein the reaction is selectively restrained by variable depth cooling device (21) and the non-reacting gas is allowed to expand inducing controlled updraft velocities. The flow rate is further controlled without pumping or restricting valving by a hydraulic head imposed on the outlet (28) by a hydraulic column in a tank (31) artificially created through a membrane (39), the height of which is controlled by a non-contaminating fluid (38). The rate of flow away from the apparatus may be independently hydraulically controlled by a float system (68).
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 reaction barrel (32). The reaction barrel (32) is provided with a plurality of rocket nozzles (41). The stream flow is channeled to and expelled through the rocket nozzles (41), thus causing the reactor barrel (32) to rotate. Rotational energy is transferred from the reactor barrel (32) to a generator (43) where electrical power is produced.
Abstract:
An apparatus for cleaning an annulus (13) formed between two generally concentric pipes (11, 12) includes a cleaning head (14) carried by feed tubes (15, 16) which position the head (14) at selected vertical positions within the annulus (13). The feed tubes (15, 16) carry fluid under pressure to the head (14). A valve (40) controls which of the feed tubes (15, 16) is receiving fluid under pressure. When valve (40) provides fluid through the tube (16), fluid is emitted through nozzles (18, 22, 25) in the head (14) to move the head (14) in one direction around the annulus (13) and clean the annulus (13). When valve (40) alternatingly provides fluid through the tube (15), fluid is emitted through nozzles (31, 32, 33) in the head (14) to move the head (14) in an opposite direction around the annulus (13). The head (14) may be simultaneously moved vertically within the annulus (13).
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 other 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:
Continuously flowing water contaminated with organic and inorganic materials is treated by being fed to the top of a downdraft column (25) of a hydraulic column reactor (10) and conducted to the bottom thereof to a reaction chamber (18). The pressure and temperature conditions in the reaction chamber (18) are maintained at approximately the necessary pressure and temperature to create supercritical water conditions to thereby treat the water and its lower specific gravity. The treated water can then be separated in the reaction chamber (18) into a particulate and precipitate enriched portion and a particulate and precipitate depleted portion, which portions are conducted upwardly in separate updraft columns (29, 30) and continuously removed therefrom.
