Title: Pai-Yu Polly Chiang: Innovator in Chemical Engineering
Introduction
Pai-Yu Polly Chiang is a notable inventor based in Dallas, TX (US). She has made significant contributions to the field of chemical engineering, holding a total of 3 patents. Her innovative work focuses on improving processes in chemical manufacturing and recovery.
Latest Patents
One of her latest patents is a tray assembly for gas/liquid contact towers. This invention includes a tray deck and a downcomer, featuring a mixer at the top of the downcomer and a distributor attached to the floor. The mixer incorporates at least one mixing baffle parallel to an outlet weir on the tray. The distributor consists of several spaced flow directing plates that extend downwardly toward the floor of the downcomer. Together, the mixer and distributor ensure even liquid flow across the surface of the subjacent tray deck.
Another significant patent involves a process for recovering a carboxylic acid from a feed stream containing the corresponding ester. In this process, a carboxylic acid, such as acetic acid, is extracted from an aqueous feed stream that includes the corresponding ester, an alcohol, and a small amount of water. The method involves catalytically dehydrating the alcohol to produce the corresponding ether and water, which then reacts with the ester to generate a liquid carboxylic acid-rich product stream. The acid is subsequently recovered through distillation.
