摘要： There is provided a process for the formulation of an oil-in-water emulsion from a produced hydrocarbon crude which includes a water-in-oil emulsion. A surface-active chemical system is added with agitation to the crude when such crude is at a temperature of from about 100.degree. to about 200.degree. F., in a quantity sufficient to formulate and then sustain an oil-in-water emulsion at pipeline conditions of temperature and shear. Water-content is from about 15 percent to about 35 percent by weight. Viscosity is sufficiently low for pipeline transportation. Any excess water is separated from the formed oil-in-water emulsion prior to pipelining. The oil-in-water emulsion is one that can easily be dewatered and desalted to the necessary marketing specifications at the downsteam end of the pipeline, using known technology.

摘要： The invention comprises a multi-vessel reaction apparatus useful for reacting phosphate rock and sulfuric acid in which the reaction slurry undergoes intra- and inter- vessel circulation (preferably through a draft tube). The solution portion of the slurry in a first vessel or set of vessels (the "dissolver") is preferably maintained at at lower sulfate ion concentration and the solution portion of the slurry in the second vessel or system of vessels (the "crystallizer") is preferably maintained at a positive sulfate ion concentration. Also preferred are means for maintaining the second vessel or set of vessels at a reduced pressure. Most preferred is that means be included in at least one said vessel for incorporating a crystal modifier (e.g. a sulfonic acid, a sulfonic acid salt, tall oil fatty acids or alkoxylated or esterified tall oil fatty acids) in the crystallizer. The system can be used in the anhydrite, hemihydrate or gypsum types of processes.

摘要： In a continuous process for recovery of values from a solid carbonaceous material, the carbonaceous material is pyrolyzed in the presence of a particulate source of heat to yield a particulate carbon containing residue of pyrolysis and volatilized hydrocarbons while simultaneously the volatilized hydrocarbons are hydrogenated. The particulate source of heat is formed by oxidizing carbon in the solid residue to heat the particles. Hydrogen for hydrogenation is obtained by reacting at least a portion of the hot particulate carbon containing residue of pyrolysis with steam prior to feeding the hot particulate residue to the pyrolysis reaction zone. Steam and/or carbon dioxide can be introduced into the pyrolysis reaction zone to react with carbon containing residue contained therein. The particulate source of heat can be introduced to the pyrolysis reaction zone over an overflow weir. The hydrogen and the particulate source of heat can be formed simultaneously in an oxidation-conversion zone. The volatilized hydrocarbons can be further hydrogenated in a vapor hydrogenation zone.

摘要： Carbonaceous materials are pyrolyzed by simultaneous feed of the carbonaceous materials and a particulate source of heat to a cyclone reactor-separator wherein the centrifugal forces separate the vaporized product of pyrolysis from the solids. The carbon in the solids is partially combusted for recycle to the cyclone reactor separator and the vaporized products quenched and recovered. The yield of liquid hydrocarbons may be maximized.

摘要： In a continuous process for recovery of values contained in a solid carbonaceous material, the carbonaceous material is comminuted and then subjected to flash pyrolysis in the presence of a particulate heat source to form a pyrolysis product stream containing a carbon containing solid residue and volatilized hydrocarbons. After the carbon containing solid residue is separated from the pyrolysis product stream, values are obtained by condensing volatilized hydrocarbons. The particulate source of heat is formed by oxidizing carbon in the solid residue. Apparatus useful for practicing this process are disclosed.
