20070193873 - 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...

20070193874 - Method and device for improved fermentation process: An improved method and device is accomplished for ethanol production using an in-line extraction of ethanol by ultrasonic atomization, thereby removing the effect of the ethanol inhibition factor that adversely affects the rate and yield. The in-line removal of ethanol as it is formed increases the fermentation rate, improves the... Agent: Brian D. Bellamy

20070187225 - Method for process water treatment in olefin plants: A method is described for process water treatment in olefin plants having at least one process steam generator (W1) and at least one cracking furnace (O) for steam cracking of hydrocarbons. It is proposed to pass the process water for process water stripping to the process steam generator (W1) and... Agent: Millen, White, Zelano & Branigan, P.C.
