Energy audit proposal for industry applied to a case study in the plastics sector

Abstract

An electric type 2 energy audit towards the industry sector is proposed based on 4 stages: 1) General review of the organization, 2) Energy assessment, 3) Saving potential identification and 4) Improvement proposals of energy efficiency. Energy assessment is mainly emphasized in which, by means of the ISA-88.01 standard, the data-collection process and its analysis is carried out bearing in mind 4 axes: i) Industry equipment, ii) Electric Installations and power quality, iii) Industrial processes and iv) Industrial habits and practices. The present proposal is applied to a case study of an enterprise from the plastics sector where it is important to mention that: 75% of the total energy consumption is represented by three molding machines. A series of actions are proposed in order to implement in the industry case study and consequently, improving the energy efficiency in 7, 25% and also optimizing production.
