摘要： A method of improving hydrocarbon recovery from oil sands, oil shale, and petroleum residues includes adding a polymeric or nonpolymeric processing aid capable of sequestering cations, such as the multivalent calcium, magnesium and iron cations. The hydrocarbons are preferably contacted with the processing aid before a primary separation of the hydrocarbons in order to increase bitumen recovery. A processing aid is provided in an effective amount to increase the liberation of the hydrocarbons from inorganic solids, particularly when the source is a poor processing ore. Preferred processing aids include citric acid or a polymeric acid selected from polyacrylic acid, polymethacrylic acid, salts of these acids, partial salts of these acids, and combinations thereof. The processing aids significantly increase the hydrocarbon recovery typically with concentrations less than 50 ppm and the polymeric processing aids can also provide beneficial flocculation of solids in tailings slurry.

摘要： A method for using a defoaming formulation useful as an antifoaming agent, a foam controlling agent, or a defoaming agent. The method comprises adding the defoaming formulation that comprises one or more alkoxylate species to a system, wherein the one or more alkoxylate species is characterized as Acc-[(Ox)i]n, wherein Acc is an acceptor having a functionality of n ranging between 1 and about 100. (Ox)i are oxide blocks, each oxide block having a composition comprising from 1 to 150,000 units of oxide species selected from ethylene oxide, propylene oxide, butylene oxide or combinations thereof and i ranges between 1 and about 10. The composition of adjacent oxide blocks is different and the average molecular weight of the one or more alkoxylate species is greater than about 2500 gmole−1. Some embodiments of the present inventions have mixtures of alkoxylate species having average molecular weights between about 5000 and about 3,000,000 gmole−1.

摘要： A method includes diluting a bitumen source, such a bitumen froth from a hot water extraction process, with a hydrocarbon diluent such as naphtha, contacting the bitumen with a zone settling aid such as a polyoxyalkylate block polymer, flocculating water and fine solids in the diluted bitumen, separating the flocculated water and fine solids from the solvent-diluted bitumen, and producing dry, clean diluted bitumen. Preferably, the diluted bitumen will have less than 1.0 wt % water, but most preferably less than 0.7 wt % water. The method may further comprise maintaining the diluted bitumen under conditions that avoid the precipitation of asphaltenes from the bitumen, preferably such that the dry, clean diluted bitumen comprises essentially all, such as greater than 96%, of the asphaltene content from the bitumen source. Counter-current flow may be performed in a series of zone settling stages, such as with gravity settling.
