Abstract: Circulating oil used for removal of sulfur in sour gas wells is contacted with an aqueous solution of a lower polysulfide of an alkali metal or ammonia to form a higher polysulfide of the alkali metal or ammonia, and the oil is separated from the higher polysulfide. The higher polysulfide is converted to lower polysulfide by precipitating part of the sulfur contained therein, and the lower polysulfide is recycled for oil desulfurization.

Abstract: A process is described for separating salt (sodium chloride) from the polyglyceride-containing organic phase of the heavy ends waste or glycerine foots still bottoms obtained in conventional manufacture of glycerine via hydrolysis of epichlorohydrin or glycerol dichlorohydrins. In this process, the heavy ends wastes made up primarily of salt and polyclycerides and containing less than about 6% by weight water are treated at elevated temperatures with sufficient amounts of n-butanol to bring about precipitation of the salt followed by separation of the n-butanol-containing liquid phase substantially free of salt from the precipitated salt, cooling of the separated liquid phase to a temperature at which the n-butanol phase separates from the substantially salt-free polyglyceride phase without further salt precipitation and recovery of the n-butanol from the phase-separated polyglyceride phase.

Abstract: A process is disclosed for demetallizing heavy hydrocarbon oils, by contacting the oil at elevated temperature with acidified active carbon. The process is particularly useful as a pretreatment of the heavy hydrocarbons for subsequent catalytic processes which are impared by metals such as nickel and vanadium.

Abstract: Heat energy, preferably from a low grade energy source, is concentrated and transferred to another medium by a multi-zone steam absorption procedure.

Abstract: Process for recovery of heat characterized by the concentration of heat from a heat source and transfer of the heat to raise the temperature of a heat receiving medium above that of the heat source.

Abstract: A process is disclosed for reducing the level of compounds of certain metals from hydrocarbon liquids by contacting said metal compound-bearing hydrocarbon with acidified active carbon. The process is particularly useful for preferentially removing organo lead compounds from gasolines at mild conditions, with only small removal of organo manganese antiknock compounds such as methyl cyclopentadienyl manganese tricarbonyl which may be present.

Abstract: A hydrogen sorbent composition comprising a lanthanum pentanickel sorbent and a thermoplastic elastomer binder is disclosed. Also disclosed is the use of the composition in storing hydrogen and in the purification of hydrogen-containing streams.

Abstract: A method and apparatus is provided for monitoring metals concentration in fluid streams, and particularly for detecting rapid changes in metal concentrations in hydrocarbon streams.
