Patent number: 7947641Abstract: The invention relates to a concentrate for the effective, environmentally friendly treatment of oil-polluted stretches of ground and the cleaning of oil-contaminated surfaces, said concentrate containing an emulsifier, a vegetable oil and ethanol. The emulsifier is preferably a non-ionic surfactant with an HLB value between 7 and 8. The vegetable oil is preferably selected so that it is liquid at temperatures above 5 DEG C. Oils containing unsaturated fatty acids, in particular germ oils are especially suitable. For its application as a treatment for stretches of ground, the inventive concentrate is diluted with water to form a cleaning solution and is applied to the oil-contaminated surface that is to be treated. The oil is emulsified in the inventive cleaning solution and is detached from the particles of the ground. The oil degrades in a significantly easier manner in the emulsified state. To clean oil-contaminated surfaces, the cleaning solution is sprayed onto the latter.Type: GrantFiled: November 1, 2006Date of Patent: May 24, 2011Assignee: Swisstech Holding AGInventor: Werner Kroh

Patent number: 7897544Abstract: The invention discloses a compounded hydrocarbon oil which comprises a base hydrocarbon oil, preferably a mixture of paraffinic hydrocarbons, propylene carbonate, and a liquid fatty acid containing at least 12 carbon atoms per molecule, preferably tall oil fatty acid. The volume ratio of propylene carbonate to liquid fatty acid is from about 3.5 to 1 to about 7 to 1. Preferably the concentration of propylene carbonate is from about 0.002 gal/gal oil to about 0.0057 gal/gal oil and the concentration of the liquid fatty acid is from about 0.0003 gal/gal oil to about 0.0015 gal/gal oil. The invention further comprises a method of compounding the compounded hydrocarbon oil and an oil base drilling fluid prepared from the compounded hydrocarbon oil. Preferably the compounded hydrocarbon oil is characterized by an increase in the low shear rate viscosity of the oil of at least 5,000 centipoise or mixing 7.5 lb/bbl of an organoclay therein.Type: GrantFiled: December 16, 2005Date of Patent: March 1, 2011Assignee: Texas United Chemical Company, LLCInventors: James W.

Patent number: 7871962Abstract: A drilling fluid having an oleaginous fluid that forms the continuous phase; a non-oleaginous fluid, which is the discontinuous phase; a primary emulsifier in sufficient concentration to stabilize the invert emulsion; and a rheology modifier, which serves to moderate the rheology change across a temperature range of 40 to 150° C. The rheology modifier may be a dimer poly-carboxylic C12 to C22 fatty acid, trimer poly-carboxylic C12 to C22 fatty acid, tetramer poly-carboxylic C12 to C22 fatty acid, mixtures of these acids, or a polyamide wherein the polyamide is the condensation reaction product of a C12-C22 fatty acid and a polyamine selected from the group consisting of diethylenetriamine, triethylenetetramine; and pentaethylenetetramine. The drilling fluid preferably includes a weighting agent or bridging agent which may be selected from galena, hematite, magnetite, iron oxides, illmenite, barite, siderite, celestite, dolomite, calcite as well as combinations and mixtures of these and similar compounds.Type: GrantFiled: August 25, 2003Date of Patent: January 18, 2011Assignee: M-I L.L.C.Inventors: Arvind D.
