Abstract
The application of a method for energy planning in order to reduce the gas consumption for a hot dip galvanizing process in a metallurgy company based on ISO 50001 standards was conducted in this research. The gas consumption for the company represents around the 75% of the total energy consumption for the company, indicating that the energy saving potentials are in the gas consumption. Three variables were taken from real data, gas consumption, level of production, and time; so, that to obtain energy performance indicators such as base line and goal line, consumption ratio with respect to the levels of production, base 100 efficiency indicators, and accumulated tendency of consumption or CUSUM. With an average production rate of 20000 m2 per day, these indicators allowed setting objectives and goals to reduce the levels of gas consumption through the implementation of good manufacturing practices and production planning. For this case of study of a hot dip galvanizing process, were calculated saving potentials until 10% of gas consumption. The implementation of this method allows determining energy saving potentials in order to reduce greenhouse gases emissions and operational costs for the plant.
