Eficiência energética em uma indústria de fertilizante: um estudo de caso

Abstract

According to the National Energy Balance, the industry is in the ranking of electricity consumption with 37.4%, ranking first in sectoral comparison. Since the nation has become increasingly concerned with issues related to energy security and linked to this, the scarcity of natural resources, energy efficiency is indicated as a solution to many of the problems highlighted. From this, energy efficiency work was developed in a fertilizer industry, with the aim of achieving the project goal. The methodology used was based on the use of the DMAIC tool that comes from the Lean Six Sigma methodology, which aims to increase assertiveness in a production process and reduce losses. In this way, based on tariff analysis, work with electric motors, reactive energy consumption, reflectors, educational measures and consumption during peak hours were developed. With this, the objective of working efficiently with electrical energy was achieved and thus, reducing the unit's consumption and, ultimately, achieving the preestablished smart goal.
