Distillation: processes, separatory inventions 06/07

20070144886 - Process for providing ethanol: The invention is a process for the purification of ethanol. In one embodiment the process comprises boiling a degassed beer feed (106) in a pre-boiler (110) to provide a vapor by-pass fraction (112) that by-passes the conventional beer column and is fed into the rectifier column (124). The process allows... Agent: E I Du Pont De Nemours And Company Legal Patent Records Center

20070137997 - Ethanol continuous flow boiler: An improved boiler that allows distillation of ethanol from a continuous flow of a hydrous feedstock compound, which may be beer or other semi-solid substance. The internal compartment of the boiler is separated into different zones by a plurality of primary baffle plates and secondary baffle plates. The hydrous feedstock... Agent: Carlton Fields, Pa

20070131532 - Method and device for treating water: Purified water for special purposes is produced using a falling-film multieffect evaporator. From the feed water, each effect produces a steam phase and a water phase. The steam phase is used for heating in the subsequent evaporating step, whereby the steam phase condenses to product water, and the water phase... Agent: Kusner & Jaffe Highland Place Suite 310

20070131533 - Distillation method: Disclosed is a method for distilling, e.g. ethanol from a mash or must. According to said method, a fluid (1) that is fed to a first distillation column (stripper, 13) and a distillate (4) of the first distillation column (13) are delivered to a second distillation column (rectification column, 14).... Agent: Cohen, Pontani, Lieberman & Pavane

20070131534 - System and method of passive liquid purification: The present invention relates to systems and related methods of water purification by distillation that will operate in a self-contained mode using a passive heat source, such as, without limitation, solar heat, air conditioning waste heat, or waste heat from the exhaust or cooling systems of an internal combustion engine,... Agent: Sheppard Mullin Richter & Hampton LLP

20070131535 - Utilizing ionic liquids for hydrofluorocarbon separation: The present invention relates to a process for separating close-boiling and azeotropic components of mixtures, wherein said mixtures comprise at least one hydrofluorocarbon compound, using at least one ionic liquid....
