摘要： Described herein is a method of controlling bitumen quality in a process stream within a solvent-assisted bitumen extraction operation, for instance a hydrocarbon stream from a froth separation unit (FSU). Bitumen quality is a measure of the amount of selected contaminants in the process stream. Contaminants may include asphaltenes (comprising metal porphyrins), sulfur, and inorganic solids (comprising inorganic elements, e.g. Si, Al, Ti, Fe, Na, K, Mg, and Ca). First, the amounts of selected contaminants are measured. Next, these measured values are compared to maximum reference values. If one or more of these contaminants is higher than the maximum reference value, at least one variable of the solvent-assisted bitumen extraction is adjusted to improve bitumen quality.

摘要： Described is a method of operating a cyclic solvent-dominated recovery process (CSDRP) for recovering viscous oil from a subterranean reservoir of the viscous oil to enhance recovery effectiveness. The cyclic solvent process involves using an injection well to inject a viscosity-reducing solvent into a subterranean viscous oil reservoir. Reduced viscosity oil is produced to the surface using the same well used to inject solvent. The process of alternately injecting solvent and producing a solvent/viscous oil blend through the same wellbore continues in a series of cycles until additional cycles are no longer economical. Conventionally, the solvent composition remains constant over time within each injection cycle and among cycles. In the present method, by contrast, the solvent composition is varied over time thereby providing operational benefits as described herein.

摘要： A method and an apparatus for cleaning of the perineal and the adjacent areas of a human body after using a toilet are disclosed. The method comprises cleaning the said areas with dilute soap solution delivered by gravity drainage, or a soap solution-air suspension delivered from a dispenser, and rinsing the cleaned areas with water delivered by gravity drainage or from a water dispenser. The apparatus comprises either reservoirs holding soap solution and rinse water that are hung from a decorative stand, or dispenser for soap solution-air or water-air suspension. Advantages over prior art include portability for indoor and outdoor use, compatibility with a western or a squat toilet, operability with atmospheric pressure water, affordability because of lower cost, acceptability because of easier installation and placement away from the toilet bowl, and comfortability of use by people suffering from itches, inflammation, or hemorrhoids.
