Abstract: This invention relates to the reduction of oxidized sulfur compound (SOX) emissions produced during combustion of sulfur (S)-containing combustible compounds. More particularly, this invention provides a method for reducing such emissions wherein the combustible compound is mixed with an admixture of a water soluble and a water insoluble sulfur sorbent. Use of such admixtures, remarkably, produces a reduction in the SOX level far greater than would be expected based on the activity of each sorbent alone. Extremely viscous hydrocarbons can be burned as preatomized fuels, which can also be mixed with sorbent admixtures. Clean burning fuels comprising sulfur-containing combustible compounds and sorbent admixtures are also provided.

Abstract: A method utilizing a portable hydraulic apparatus for cleaning the hydrocarbon contaminated sludge deposit of an oil storage tank with a fluidizing agent, the tank having a floor, a side wall and a passageway through the side wall positioned adjacent the floor of the tank, comprises a frame having a central portion and first and second end portions. The frame is configured and dimensioned to pass through the passageway. A pair of independently movable endless chain belts are position on opposite sides of the frame for selectively moving the frame within the oil storage tank to selected locations. A hydraulic line coupled to the central portion of the frame discharges the fluidizing agent onto an adjacent first portion of the sludge deposit so as to form a pool of sludge and fluidizing agent. A suction pump is positioned on the central portion of the frame for drawing up the pool of sludge and fluidizing agent.

Abstract: An apparatus and process adapted to clean oil contaminated vessels which uses a closed fluidized system through which fluidized sludge is recirculated to be sprayed under pressure on interior walls of the vessel. Emulsifying agents are added to the vessel to initially form a pool of fluidized sludge in the vessel which is then conveyed to a tank and from the tank conveyed to a high pressure spray where it is sprayed onto the walls to fluidize more sludge.

Abstract: Growth of Acinetobacter Sp. ATCC 31012 on various substrates and under varying conditions has been used to produce two classes of extracellular microbial protein-associated lipopolysaccharides (the "emulsans") which, on a weight-for-weight basis, are probably the most efficient emulsifiers discovered and which possess certain characteristics that permit these unique extracellular microbial lipopolysaccharides to be widely used in cleaning oil-contaminated vessels, oil spill management, and enhanced oil recovery by chemical flooding. Emulsans and apoemulsans, both of which biopolymers are strongly anionic, exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and cyclic components. In addition, these extracellular microbial polysaccharides as well as their O-deacylated and N-deacylated derivatives are adsorbed on and capable of flocculating aluminosilicate ion-exchangers, such as kaolin and bentonite.

Base hydrolysis under mild conditions of the emulsans and apoemulsans produces derivatives (the ".psi.-emulsans" and "apo-.psi.-emulsans", respectively) which are completely N-acylated and partially to completely O-deacylated. Emulsans and apoemulsans, both of which biopolymers are strongly anionic, exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and cyclic components.
