Design and Pinch Analysis of Methyl Acetate Production Process using Aspen Plus and Aspen Energy Analyzer

Nagamalleswara Rao Kanidarapu, G. Koteswara Reddy, P. Rajendra Prasad, V. Sujatha


This study deals with the design and heat integration of Methyl Acetate production process. Initially, Methyl Acetate production process plant is designed using Aspen Plus. Methyl acetate obtained is 99.99% pure and the designed plant is safe to environment with less emissions. For the developed process plant, pinch analysis is applied using Aspen Energy Analyzer. Improved Heat exchanger networks (HEN) is obtained with retrofit analysis of the process plant. The retrofit design saves the energy of the process by minimizing the operating costs. In retrofit analysis, four new heat exchangers are added to the base case HEN which reduced the operating cost with the payback period of 0.9 years.

Keywords: Pinch analysis, Aspen Plus, heat exchanger networks (HEN), Aspen Energy Analyzer, retrofit analysis
