Distillation: processes, separatory inventions 06/08

20080135396 - Separation method: A feed stream is fed to a first distillation stage comprising at least one distillation column (stripper) and the distillate from the first distillation stage is fed to a second distillation column (rectifier). The feed stream is sub-divided into two streams and fed to two distillation columns, in such a... Agent: Cohen, Pontani, Lieberman & Pavane

20080128262 - Separation process for methyl acetate hydrolysis and apparatus thereof: A separation system for a methyl acetate hydrolysis is provided. The separation system comprises a reactive distillation system, a reflux system, a first separation system and a second separation. The reactive distillation system allows the hydrolysis of a methyl acetate solution to generate a first mixture and a second mixture.... Agent: Volpe And Koenig, P.c.

20080128263 - Process for producing acrylic acid: The present invention reduces a cost of a polymerization inhibitor required in purification of high purity acrylic acid through distillation. According to the present invention, a condensate obtained through the distillation of acrylic acid in a distillation column is fed to a flasher, to thereby obtain acrylic acid as a... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, P.c.

20080128264 - Three-phase extractive distillation with multiple columns connected in series: A novel method for connecting multiple existing columns which are retrofitted into vapor-liquid contacting devices with trays or packings suitable for the operation of a three-phase (vapor-liquid-liquid) extractive distillation column for aromatics recovery. The retrofitted columns are connected by a vapor transfer line to transfer the vapor phase from the... Agent: Law Office Of Spencer Chen
