Abstract:
The invention relates to a stirred tank reactor for gas-liquid mass transfer in a slurry. The reactor includes a reactor tank (1) having a first volume (V 1 ), a drive shaft (2) that extends vertically in the reactor tank, a motor (3) for rotating the drive shaft (2), a main impeller (4) which is a downward pumping axial flow impeller attached to the drive shaft (2) to create a main flow pattern in the reactor tank, and a gas inlet (5) arranged to supply gas into the reactor tank (1) to be dispersed to the liquid. The reactor includes a mechanical gas sparging apparatus (6) comprising a dispersion chamber (7) having a second volume (V 2 ) which is substantially smaller than the first volume (V 1 ) of the reactor tank (1), the dispersion chamber being arranged coaxial with the drive shaft (2), and the gas inlet (5) being arranged to feed gas into the dispersion chamber (7), and mixing means (8, 9, 10, 11, 12) arranged within the dispersion chamber (7) for mixing the gas into liquid by dispersing the gas to fine bubbles before the bubbles enter the main flow pattern. The mixing power per unit volume inside the dispersion chamber (7) is significantly larger than the mixing power elsewhere in the reactor.
Abstract:
The current application is directed to an enclosed rotor-based cavitational and catalytic flow-through reaction chamber ("ERCCFRC") that can be employed in a variety of thermal, chemical, and fluid-mechanical processes. The ERCCFRC features a reaction chamber that incorporated a spinning rotor, generating fluid-mechanical forces and cavitation in a fluid within the ERCCFRC. The reaction chamber further incorporates one or more heterogeneous catalysts that promote specific chemical reactions.
Abstract:
Disclosed are magnetic agitation mixing systems for use with flexible container reaction vessels. In one aspect of the invention, the orientation of magnetic coupling between the impeller magnets and the external driver magnets is modified such that the coupling is neither strictly axial nor strictly radial. Also disclosed are "receiver-less" retainer configurations whereby the single-use container need not have a rigid base that defines a cup or post to engage of rotatable agitator.

Abstract:
Disclosed are an oxidation reactor for manufacturing an aromatic carboxylic acid and a method of manufacturing the aromatic carboxylic acid using the oxidation reactor. The oxidation reactor includes a reaction chamber, a stirring shaft disposed along a geometric vertical axis of the reaction chamber, and at least two stirrers, each including stirring blades, each stirring blade having either a curved portion or a bent portion formed on an end of the stirring blade to enable fluid to flow in the reaction chamber while preventing the fluid from remaining in the reaction chamber, and each stirring blade being extended radially along a direction perpendicular to the vertical axis to be rotated.
