Chemtech's Energy Efficiency Methodology

Abstract Th ere would be no lack of energy if all the existent technologies were applied for a more efficient energy use, said Greenpeace – Brazil. Aiming at an energetic sustainability of his clients, Chemtech developed a methodology that primes for the conscientious use of energy, contributing to the reduction of industries' energy consumption. This methodology is based on the traditional energy audit, consisting of an initial assessment, data survey and measurements, resulting in actions to reduce overall energy consumption, allied to a differentiated implementation. The audit embodies a tariff analysis, correction of power factor, pre feasibility study of mechanical and electrical measures and process analysis. A conceptual project is elaborated on selected measures (i.e. automation, production, electrical installations and utilities) after a detailed feasibility study. Differing from a traditional audit, a client's energy management team is established ai ming the development of an internal control of energy, with the implementation of an energy efficiency awareness program for all employees and controlling the energy consumption through established energy indicators. Another differential of Chemtech's work is the approach used to develop the audit. Each milestone of the audit consists of several steps, each step used to augment the consistency of gathered data and refine obtained results through recurring meetings with the client covering specific topics. The next step is only initiated after the client's acceptance of data and results pertaining to the previ ou s one. This approach raises the consistence and acceptance of the developed work, like a helix, guaranteeing the overall development efficiency, so as the consistency of the project.
