Distillation: processes, separatory inventions 08/09

20090205945 - Process and apparatus for alkylation of benzene with aliphatic mono-olefin compound: Processes and apparatus for the alkylation of benzene with mono-olefin aliphatic compound in at least two reaction zones in the presence of solid alkylation catalyst use a crude distillation of the reaction effluent passing between reaction zones to remove a substantial portion of the alkylbenzene. The processes reduce the amount... Agent: Honeywell/uop Patent Services

20090205946 - Integrated compressor/stripper configurations and methods: Contemplated solvent regenerators include a flash drum in which lean solvent from the regenerator is flashed, and from which supplemental steam is recovered that is then fed back to the regenerator using a compressor, and most preferably a thermocompressor. Such devices have a substantially reduced net steam and energy requirement... Agent: Fish & Associates, PC Robert D. Fish

20090200153 - Method for producing and dehydrating cyclic formals: Processes are described which comprise: (a) providing a mixture comprising a cyclic formal and water, wherein the mixture has a cyclic formal concentration and a water concentration; (b) bringing the mixture into contact with an aqueously selective membrane; (c) creating a pressure differential across the membrane; and (d) obtaining a...
