The process intensification (PI) technique involves changing a tower?s internals and operating mode and the separate movement of the liquid and vapor phases. This can significantly increase column throughput and reduce energy requirements, while improving separation performance. PI is a set of innovative principles for enhancing the driving forces and synergistic effects in a process to obtain: dramatic reductions in the size of a plant needed to achieve a production objective, significant increases in the production capacity within a given equipment volume, a step reduction in energy usage per ton of product, or a marked cut in the formation of wastes and byproducts. PI encompasses recognized technologies in reactor engineering, heat exchange, mixing, and distillation. Particularly in distillation systems, PI has received much attention, with the aim of increasing both energy and separation efficiency.
