Study of Energy Intensity and Energy Conservation Opportunities in Pharmaceutical Industry

Abstract

In this study the authors conducted an evaluation of energy management with the aim of identifying energy consumption used for production process activities in the pharmaceutical industry. Based on data on energy use in the productivity process, the Energy Intensity (EI) value ranges from 0.020-0.695 GJ/kg. From these IE values, in each productivity process the average IE value can be used as a reference as an energy conservation limit value of 0.125 GJ/kg. From the description of the pattern of total energy consumption, it can be seen that the use of electrical energy tends to be greater, namely around 66.37% compared to the consumption of CNG and diesel which only consume 31.80% and 1.83%. The total energy use for electricity is an average of 1,105.56 MWh/month, CNG fuel is 1,895.54 MMBTU/month and diesel is 3.04 liters/month. In terms of equipment systems, the largest electricity consumption is borne by the HVAC system which consumes around 55.56% of the total electrical energy. From the description of the distribution of electrical energy use, it can be said that the HVAC system is SEU (Significant Energy Use). Based on actual conditions, it shows that the actual COP value obtained is 2.49-2.98 with a design deviation of around 1.24%-27.74% and an EER value of 1.18-1.41 kW/TR with a design deviation value of around 1.17%-38.22%. COP and EER values can still be increased so that performance is more optimal.
