Abstract: A mixing apparatus for mixing first salinity fluid with a second salinity fluid, the mixing apparatus comprises a down tube having a side wall, an open upper end and an open lower end, and a plurality of apertures selectively located in the side wall of the down tube. At least some of the apertures have an arm with an opening therein about the aperture to facilitate inflow of fluid to the down tube through the openings. A fluid inlet and a fluid outlet are provided at the open upper end and open lower end respectively of the down tube so that the first salinity fluid in use enters the down tube through the fluid inlet and the apertures and is discharged therefrom through the fluid outlet.

Abstract: This invention is a reactor and a process for the conversion of organic waste material such as municipal trash, sewage, post-consumer refuse, and biomass to commercially salable materials. The invention produces the following: 1. Maximum energy conversion from the organic material 2. High volume consumption of the organic feed material 3. Less pollution of gaseous products than prior art systems 4. Solid residuals for disposal are minimal and non-hazardous. The conversion is accomplished by combining anaerobic gasification and pyrolysis of the feed organic material and making it into synthetic gas. The synthetic gas is a mixture of hydrocarbons (CxHy), hydrogen, and carbon monoxide with small amounts of carbon dioxide and nitrogen. An essential feature of the invention is a hot driver gas, devoid of free oxygen and rich in water, which supplies the entire thermal and chemical energy needed for the reactions.

Abstract: A mixing apparatus for mixing relatively low salinity fluid with relatively high salinity fluid comprises a housing having an upper end and a lower end, a fluid inlet at or near the lower end, and a fluid outlet at or near the upper end, wherein the relatively high salinity fluid in use enters the housing through the fluid inlet and is discharged from the housing through the fluid outlet. A feed tube is provided and has a first end connectable to a source of relatively low salinity fluid and second end for introducing relatively low salinity fluid to the housing to mix the relatively high salinity fluid with the relatively low salinity fluid to form a fluid mixture. At least one power generator is associated with the housing, and is driven by the mixing of the relatively high salinity fluid with the relatively low salinity fluid.

Abstract: A device and method for disposal of waste fluid comprises directing the waste fluid having a first osmotic energy potential from a source through a feed tube into a larger mixing chamber located in a body of water having a second osmotic energy potential. Thereafter, water is introduced from the body of water into the mixing chamber. Mixing occurs within the mixing chamber between the waste fluid and water from the body of water to form a waste fluid/water mixture, the mixing being driven at least in part by osmotic energy potential difference between the waste fluid and the water in the body of water. The chamber has sufficient length to facilitate substantial mixing of the waste fluid with water from the body of water. The waste fluid/water mixture is allowed to flow into the body of water from an opening in the chamber.

Abstract: A multi-step process for desulfurizing liquid petroleum fuels that also removes nitrogen-containing compounds and aromatics. The process steps are: thiophene extraction; thiophene oxidation; thiophene-oxide and -dioxide extraction; raffinate solvent recovery and polishing; extract solvent recovery; and recycle-solvent purification. The thiophene oxidation is accomplished with hydrogen peroxide and the extraction solvent is acetic acid in combination with secondary solvents. The operating conditions in the process are relatively mild at near ambient pressure and less than 145° C. throughout the process, and the only chemical consumed in the process is hydrogen peroxide. The process design can be modified to accommodate a variety of liquid hydrocarbon feeds.

Abstract: Solid carbonaceous fuel is dried to a desired moisture content, cooled, and stored in an atmosphere having a controlled humidity and oxygen content to prevent heat generation which causes spontaneous combustion. A suitable atmosphere is produced by displacing air in a storage enclosure with dehumidified combustion gases.

Abstract: Hydrocarbon tars of high asphaltene content such as tars obtained from pyrolysis of coal are dissolved in a solvent formed from the hydrogenation of the coal tars, and the resultant mixture hydrogenated in the presence of a catalyst at a pressure from about 1500 to 5000 psig at a temperature from about 500.degree. F to about the critical temperature of the solvent to form a light hydrocarbon as a solvent for the tars. Hydrogen content is at least three times the amount of hydrogen consumed.
