US Classification:
1662701, 568618, 558 41, 558 44, 558 34
Abstract:
A method is disclosed for manufacturing surfactants for utilization in petroleum industry operations. The method comprises providing a bio-lipid. The bio-lipid can include one or more medium-chain or long-chain fatty acids, such as Lauric acid, Myristic acid, Palmitic acid, Stearic acid, Palmitoleic acid, Oleic acid, Ricinoleic acid, Vaccenic acid, Linoleic acid, Alpha-Linoleic acid, or Gamma-Linolenic acid. Fatty acid alkyl esters are produced by reacting the bio-lipid with a low-molecular weight alcohol. The fatty acid alkyl esters are reduced to a fatty alcohol. The fatty alcohol is dimerized to form a Guerbet alcohol, which is a precursor to producing surfactant for utilization in a petroleum industry operation, such as an enhanced oil recovery process.

International Classification:
C08J 900
US Classification:
521113
Abstract:
Surface coating methods and compositions are disclosed which eliminate many of the disadvantages associated with known coating processes from pollution, equipment, materials, energy, labor and cost standpoints. According to techniques described, thermosetting liquid compositions containing film-forming solids are formulated, then conveyed in the foam state toward a surface, and upon foam disintegration, form a film of solids on the surface. The foamable thermosetting resin compositions contain a curable resin having a free hydroxyl or carboxyl group, a curing agent consisting of a lower (C. sub. 1 -C. sub. 4) alkoxylated amine for reaction with the resin hydroxyl or carboxyl group and a liquid blowing agent consisting of a C. sub. 1 -C. sub. 4 alkanol which is also a by-product of the thermosetting reaction.

Abstract:
A method of recovering polychlorinated biphenyls by mixing and reacting a soluble polymer with polychlorinated biphenyls in non-aqueous solvent to form a precipitate reaction complex of the polymer and biphenyl, and separating the precipitate from the solvent, said polymer having the formula: ##STR1##.

Abstract:
Foamed hot melt adhesives are made and employed by methods which offer significant advantages and economies. The method employs surfactant stabilizers in making hot melt adhesive foams which are very useful in bonding substrates with efficiency and superior bond strengths. Continuous and reliable foaming operations are achieved with a uniform quality and output of foamed materials. Hot melt adhesives are also capable of being foamed with relatively simple mechanical apparatus and under conditions which provide considerable savings of energy. The number of hot melts which can be foamed employing the present technique in a controlled manner is unlimited. The method of stabilization is conducted at low or ambient pressures and resulting stabilized hot melt adhesive gas dispersions may then be pumped with pressurization and dispensed with immediate foaming.

International Classification:
C10G 2906
US Classification:
2082625
Abstract:
A method of recovering polychlorinated biphenyls from solution, which comprises a multi-step method of mixing and reacting an alkali metal or alkaline earth hydroxide in glycol solution with polychlorinated biphenyls in non-aqueous solvent to form biphenyl phenoxy-type anions, separating the glycol solution containing biphenyl phenoxy-type anions from the non-aqueous solvent, and separating the biphenyl phenoxy-type anions from the glycol solution.

International Classification:
E21B 43/16 C09K 8/584 C09K 8/588 C09K 8/58
Abstract:
Additional oil recovery is obtained from a reservoir with a composition comprising at least a coupling solvent typically employed in waterborne coating compositions. Provided herein are embodiments of methods of recovering hydrocarbons using at least one coupling solvent, such as an oxygenated coupling solvent. The coupling solvent increases the mutual solubility with water at the injection temperature to facilitate the mixing and injection, particularly with an optional co-solvent. The coupling solvent helps mitigate formation plugging and improve performance when injected into a formation, as the solvent mixture moves from being miscible in the injection field water to being miscible in the reservoir oil, mobilizing the reservoir oil to increase oil recovery.
