HIGHLY CONCENTRATED, WATER-FREE AMINE SALTS OF HYDROCARBON ALKOXYSULFATES AND USE AND METHOD USING AQUEOUS DILUTIONS OF THE SAME |
摘要 |
The present invention relates to highly concentrated, anhydrous amine salts of hydrocarbon polyalkoxy sulfates, wherein the salts are selected from the group of substituted amines, preferably alkanolamines. The products obtained are of low viscosity and pumpable at room temperature. Due to the absence of water, the salts are highly resistant to hydrolysis, even at high temperatures. The invention further relates to the use of the compositions according to the invention in an aqueous dilution for use in oil reservoirs with the aim of achieving enhanced oil production, or for the recovery of hydrocarbons from tar sands or other surfaces or materials provided with hydrocarbon. |
