摘要： Saline waters are made suitable for use in large quantities in petroleum refining operations by evaporative desalination of a water source having a dissolved salt content of at least 30,000 ppmw with the heat liberated during the steam condensation used as low quality heat for petroleum refining operations. Sea water is most suitable for evaporative purification processes.

摘要： Fine, solid particles in a gas stream, especially fly ash particles in the hot gas stream from a coal/coke-utilizing synthesis gas unit, are agglomerated by passage through a gas flow matrix element having a body with confined gas flow channels which bring the particles into close proximity to one another in an environment of low turbulence; a rough surface on the gas flow passages provides surface induction to promote agglomeration of the particles. The larger, agglomerated particles may then be removed from the gas stream by inertial separators such as cyclones.

摘要： The present invention is directed to a method of generating a basic water-in-oil emulsion for use in recovering hydrocarbons from a subterranean formation. The emulsion may be used to displace hydrocarbons from the formation. The emulsions used are ‘basic’ in the sense that they do not have added surfactants and are not solid-stabilized. The emulsions are made using a hydrocarbon having at least one of the following properties: (i) greater than five weight percent (wt %) asphaltene content, (ii) greater than two wt % sulfur content, and (iii) less than 22 dyne/cm interfacial tension between the hydrocarbon liquid and the aqueous liquid.

摘要： The feeding of coal slurries into a gasifier for the production of synthesis gas is improved by modifying the rheological properties of the coal particles so that conventional liquid transfer equipment can be used in the feed transfer process to the gasifier. The coal particle surface modification is accomplished by adsorbing asphaltenes derived from petroleum onto the surfaces of coal particles prior to and/or during contact with the slurry liquid. The coal particles with their surfaces thus modified exhibit lower particle-particle interaction in the liquid slurries to form a shear independent Newtonian fluid or a weakly shear thickening pseudoplastic fluid. The rheological properties of the slurries permit them to be transported reliably into a pressurized, entrained feed gasifier vessel using convention slurry pumps with a low potential expenditure of energy.

摘要： Provided are oil-in-water and water-in-oil emulsion compositions including from 0.01 to 5 wt % of a halogenated elastomer emulsifier, and optionally from to 0.5 wt % of a polyalkylene amine co-emulsifier. The emulsion compositions disclosed herein provide for increased interfacial elasticity and decreased interfacial tension at the oil-water interface to increase resistance to coalescence of dispersed water droplets of a water-in-oil emulsion or oil droplets of an oil-in-water emulsion. The emulsion compositions disclosed herein are suitable for lubricant applications due to their resistance to shear thinning.

摘要： A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of one or more oil dispersible or oil soluble polynuclear aromatic compounds, or functionalized lignin, is added or contacted with the resid or heavy oil at a point before or after the step of heating the heavy oil to coking temperatures. The addition of additives facilitates the formation of shot coke and inhibits the formation of sponge coke.
