Microwave processing applications in chemical engineering: cost analysis

Abstract

Rising fossil fuel energy costs and climate change have generated increased interest in alternative drying methods. Microwave processing applications chemical engineering industry is one possible substitute. The advantages of using microwave processing applications in chemical engineering can range from improved quality, reduced wastage; unique characteristics induced by 'volumetric' heating and increased production. However, irrespective of benefits that would accrue if the solution is put into effect, the final hurdle for industry adoption can only be made with the achievement of a financial return on investment. This study analyses the costs and benefits for implementing microwave systems and presents results for economic parameters used in cost calculations. The calculations method is outlined using a corrugated board case study. Furthermore in the age of green awakening microwave processing is argued to help improve process efficiency by using green electric supply hence reducing CO2 emissions.
