Distillation Technology
Distillation tower-a large cylindrical column packed with trays, plates or packing to achieve better contact between the two phases-usually used in industrial distillation. In the past 12 years, equipment suppliers have made continuous and substantial improvements to tower internals. For example, these include Raschig Super-Ring, sandwich packing, and high-performance distillation trays. Academia has developed very complex mathematical tools for conceptual distillation design. Many of these tools have been adopted by end users in the chemical and petrochemical industries and opened up new ways to determine the best separation scheme, process modeling and optimization. Distillation Technology The reactive distillation, which realizes chemical reaction and distillation separation at the same time, has also been extensively improved. Today, it is possible to recover the carboxylic acid produced by fermentation or to separate chiral substances using enzymatic biological reaction distillati
