摘要： A process for preparing carboxylic esters. A catalytic distillation column filled with acidic catalyst in solid phase is utilized. Alcohol is fed from the bottom of the catalytic distillation column, and carboxylic acid or carboxylic anhydride is fed from the top of the catalytic distillation column in such a manner that the carboxylic acid or carboxylic anhydride can remain in the catalytic distillation column for a sufficient time to cause the esterification to produce the carboxylic ester and water. An esterification pre-reactor can be connected in series with the catalytic distillation column to facilitate the esterification.

摘要： The present invention discloses a method for catching particles having diameters size down to the nanometer level including a first step of increasing particle diameters of particles contained in an outlet gas from a fabrication process of nano-particles or an exhaust from a combustion; and a second step of introducing the resulting effluent from the first step into a rotating packed bed. The first step involves contacting the gas/exhaust with droplets or water vapor, creating collision of the nano-particles with the droplets or condensation of water vapor using the nano-particles as condensation nuclei, so that the size of the nano-particles increases to the micro level. The second step uses the minute water drops generated from and the hindrance of the rotating packed bed to catch the micro-particles in the gas/exhaust under a relatively high centrifugal force. The first step can occur in the rotating packed bed if the gas/exhaust is introduced directly into the rotating packed bed and has a sufficient long residence time in 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in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile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.

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.
