Proposta de metodologia para elaboração de um Plano Diretor de Automação Industrial (PDAI) visando o aumento da eficiência energética em plantas petroquímicas.

Abstract

The petrochemical industry is a segment that consumes a large amount of energy in its production processes. Most of this energy originates from products derived from oil or natural gas, as a priority, and do not suffer combustion, but are consumed in the form of raw materials and another part of this energy is consumed in the form of fuel. In this way, the petrochemical industry has great significance in the context of global energy security and, considering the current scenario of globalized economy, the work of seeking greater energy efficiency in petrochemical plants is essential, as a differential for productivity gain. Thus, in this context, the use of industrial automation technology is essential due to its resources that, once properly applied, can optimize the productive processes and utilities, generating greater efficiency gains. With this vision in mind, this work presents a proposal for a methodology for the elaboration of an Industrial Automation Master Plan (PDAI), with the purpose of helping petrochemical plant managers to choose and direct their investments in automation technology, aimed at gains of energy efficiency, through a process consisting of fifteen stages of work, contemplating from the formation of the team, the planning of the activities, the alignment with the strategic planning of the company, the evaluation of the processes and automation systems existing in the plant, the diagnosis the level of excellence in plant automation under evaluation, as well as the elaboration of an action plan, evaluation of costs and benefits, consolidation, prioritization and presentation of investment proposals to achieve the desired objectives
