    摘要: A method is used to remove an unreacted alcohol from an ester product mixture by a gas stripping. The method involves the feeding of the ester product mixture into proximity of an axis of a rotating packed bed, so as to enable the ester product mixture to flow radially to come in contact with a gas which is introduced into the rotating packed bed. The unreacted alcohol and any other volatile component of low molecular weight are thus stripped from the ester product mixture by the gas entrainment, thereby resulting in production of a purified ester product which is collected at the bottom of the rotating packed bed. The unreacted alcohol and the volatile component, which are entrained in the gas, are discharged via an exit located at the top of the rotating packed bed.

    摘要: A high viscosity liquid is fed into a rotation pack bed at a position with a distance far enough from a rotation axis, creating a centrifugal force exerted on the high viscosity liquid overwhelming a drag thereof, so that it can flow radially through the rotation pack bed. A high pressure gas is introduced into the rotation pack bed peripherally and/or a suction force source is connected to a position near the rotation axis, so that a volatile component contained in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile component is removed from the high viscosity liquid. A second fluid can also be fed into the rotation pack bed to react with the high viscosity liquid, so that a reaction product is formed, and a volatile side product is removed at the same time.
