摘要:
A method for the reduction of the emission of mercury into the environment from the burning of fossil fuels with the use of polydithiocarbamic compounds. The polydithiocarbamic compounds are used for the capture of mercury from the resulting flue gases using a flue gas desulfurization systems or scrubbers. The method uses polydithiocarbamic compounds in conjunction with a scrubber to capture mercury and reduce its emission and/or re-emission with stack gases. The method is a unique process of reducing the toxic levels of mercury, which allows for the use of coal as a clean and environmentally friendlier fuel source.
摘要:
Processes for recovering hydrocarbons from subterranean formations are disclosed. The hydrocarbon can be contacted with water or steam and one or more additives, and subsequently recovered. The hydrocarbon can be selected from heavy or light crude oil, bitumen, an oil sand ore, a tar sand ore and combinations thereof. The additive can be, for example, an aromatic hydrocarbon. Compositions or mixtures including hydrocarbons, water or steam, and additives are also disclosed.

摘要:
A method of enhancing flux of tailings settling pond water from an oil sands process through a membrane separation system and purifying the water comprising is disclosed. The process comprises the following steps: (a) treating the water with an effective amount of one or more water-soluble cationic polymers, amphoteric polymers, zwitterionic polymers, or a combination thereof; (b) passing the treated water through a membrane separation system; and (c) optionally, passing the permeate from step (b) through an additional membrane separation system.
