Identificação e formulação de propostas para eficiência energética elétrica em um processo de refino de celulose

Abstract

Technological advances and the development of new raw materials brought the opportunity for all the industry apply new techniques, technologies and raw materials in their production processes. This research was carried out on manufactures of a business, evaluating the process of its main production line working with cellulose fibers. As the research aims only to the academic development so the company name was withheld, here it is referred as "Company A". The manufacture products based on cellulose fiber requires that it is refined until a specific Schopper Riegler degree (oSR) be achieved, ideal for going to production. Given the characteristics encountered in the process, there is a high energy consumption during refining of the pulp. This academic research presents a study of this process and at the end proposes improvements that could be implemented in the pulp refining plant, with a focus on energy efficiency of the process in order to reduce the cost of energy inputs and bringing products derived from this process at a cost even more competitive.
