Distillation: processes, separatory inventions 07/08

20080179175 - Desalination process: Saltwater is boiled in a vacuum generated by a pump and its water vapor exhaust is condensed into purified water.... Agent: Dr. Kurt Lehovec

20080179176 - Process for the preparation of aromatic amines: Aromatic amines are produced by catalytic hydrogenation of aromatic nitro compounds. The reaction mixture generated by this hydrogenation is then worked up by distillation in a manner which makes it possible to substantially free the amine of water with increased energy efficiency. Water free of amine and low boilers and... Agent: Bayer Material Science LLC

20080173531 - Distillation apparatus and method of use: A method and apparatus is provided for distilling and processing chemicals. The apparatus is particularly suited for processing and distilling difficult to distill compounds, and is capable of producing diesel fuel and other products from used oil at a quality level similar to that of products produced from virgin crude... Agent: Pate Pierce & Baird

20080164137 - Compositions, configurations, and methods of reducing naphtenic acid corrosivity: Naphthenic acid corrosivity of hydrocarbon feedstocks is correlated with the chemical composition of naphthenic acids, and especially with a ratio between an alpha fraction and a beta fraction of naphthenic acids. Contemplated plants, configurations, and methods are directed to reducing naphthenic acid corrosivity of hydrocarbon feedstocks by increasing the beta... Agent: Fish & Associates, PC Robert D. Fish

20080164138 - Method for obtaining a flow of hydrocarbons containing between 4 and 12 carbon atoms per molecule, with an increased quantity of linear alpha-olefins: p

20080164139 - Treatment of olefin feed to paraffin alkylation: A process for the removal of aromatic compounds from the olefin feed to a sulfuric acid paraffin alkylation by feeding a olefin containing hydrocarbon stream and a dilute alkylate stream from a paraffin alkylation to a distillation zone and removing unreacted material from said hydrocarbon stream as overheads and removing...
