Energy Management by Variable Monitoring, Specific Case Industrias Elimenticias Noel S.A. Zenú Plant

Abstract

ABSTRACT Energy resource management and energy auditing are two effective methodologies which lead to a rational energy use in the different processes or systems in the industrial sector. This article introduces a methodology focused on energy management through the monitoring of variables as well as the results obtained from its application in “Industrias Alimenticias NOEL S.A., ZENU” plant in Medellin, Colombia. The aim of this methodology is to identify the main sources of energy waste, the way energy is used, and the possibilities for better energy exploitation. The analysis consisted of the periodical measurement of electricity, fuel, water, and propane gas consumption, as well as steam generation, which are then compared to production output (consumption vs. production). Through lineal regression techniques, fixed (baseline) and variable consumption are determined for the comparison. This way, unnecessary consumption and system efficiency data are obtained respectively. By implementing this techniqu...
