Maximização da eficiência energética petroquímica através do gerenciamento do sistema de purga

Abstract

In 2012 at Brazil, about 498.4 TWh of electricity were consumed and in 2013 reached 516.3 TWh, ie an increase of 3.6% in one year. The use of energy efficiency as a method to combat energy waste is necessary.In addition to contribute to the most competitive industries, with a reduction in operating costs, even postpone the need for new power plants buildings, providing resources to other areas and contributing to environmental preservation.This paper presents a management methodology in specific industrial assets, which in addition to energy conservation (steam) aims at preserving the environment and the process reliability at a petrochemical plant. The importance of adaptation and management of vapor purge stations for condensate systems is one of the tools used to maximize energy use and thus minimize the risks of processes from traps in failure. This work presents a real case of purge systems at the end of lifecycle and technological gap, which accelerates the impact on energy losses, environmental and process safety.The information presented here are based on a practical application showing satisfactory financial and plant operational results.
