Abstract
An additive is used in a method for settling suspended finely divided inorganic solid particles from a hydrocarbon slurry. The additive comprises (a) a hydroxy-terminated polyoxyalkylate chain(s) containing polymer having at least one oxygen atom and at least one nitrogen atom and, optionally, (b) other components such as a solvent, an acid or mixtures thereof.
Claims21
A method for settling suspended finely divided inorganic solid particles from a high solids hydrocarbon, the method comprising:
- (a) admixing an effective amount of an additive with a high solids hydrocarbon containing suspended finely divided inorganic solid particles;
- and
- (b) allowing the inorganic solid particles to settle and form a settled phase, wherein the additive is an amine or alkanolamine initiated polyether;
- and the hydrocarbon includes less than 2 percent water.
An additive useful for aiding the settling of suspended finely divided inorganic solid particles from a high solids hydrocarbon comprising (i) a polyether prepared by a polyoxyalkylation of an amine or an alkanolamine initiator, (ii) an acid, and (iii) a diluent.
