In this paper, we will introduce a new dynamic operation paradigm that can be applied to existing intensified equipment to further enhance process performance. In particular, we study the use of periodic operation to manipulate and hijack the competing phenomena present in an intensified system to the benefit of economic indicators such as energy efficiency and yield. We refer to this approach as âdynamic process intensification.â
Motivated by their large energy consumption across the chemical and petrochemical industries, we focus specifically on the dynamic intensification of distillation systems. Using the canonical model of a binary distillation column, we demonstrate theoretically the benefits of dynamic intensification. We then carry out extensive dynamic optimization and simulation studies to confirm the results of the theoretical findings and quantify the magnitude of the economic benefits available in a system of practical relevance.
