O trabalho teve como base os seguintes objetivos: Conhecer o uso do vapor saturado de ?gua nos processos de tinturaria e acabamento em uma planta t?xtil; Estudar os diversos aspectos de um sistema de distribui??o de vapor, para identificar as formas em que ocorrem perdas de energia; Obter informa??es quantitativas das principais perdas de vapor no sistema de gera??o e distribui??o de vapor e mensurar as perdas, ?gua e vapor, do sistema; Utilizar o vapor flash como forma de redu??o de custo. Para isso fez-se uso da apura??o dos ganhos financeiros apresentados nas suas respectivas melhorias. Como base de dados para o desenvolvimento do trabalho utilizou-se registros de processos industriais, dados dos sistemas de utilidades, dados de an?lises de laborat?rio e de analisadores em linha, abrangendo o per?odo de 2013. Usando-se princ?pios consagrados das leis de conserva??o de massa e energia, o tratamento desses dados mostrou que as perdas de ?gua e energia no sistema de vapor s?o expressivas e que os ganhos ambientais e econ?micos que poder?o ser obtidos com a??es de melhoria s?o bastante significativas. Tomando como base os dados e resultados obtidos sugiro que os estudos futuros deem continuidade a abordagem sobre sistemas de gera??o de vapor, distribui??o e, principalmente, retorno de condensado / This study focused object a steam generation system, steam distribution and condensate return a textile plant located in Rio Grande do Norte. The work was based on the following objectives: Knowing the use of saturated water vapor in the dyeing and finishing processes in a textile plant; To study the various aspects of a steam distribution system to identify the ways in which energy losses occur; Obtain quantitative information of the main loss in steam generation system and steam distribution and to measure the losses, water and steam system; Using the flash steam as a means of cost reduction. For it was made use of the calculation of financial gains made in their respective improvements. As a database for the development of working registers are used in industrial processes, data from utility systems, laboratory data analysis and on-line analyzers, covering the period 2013. Using the principles set conservation laws mass and energy, those data showed that the loss of water and energy in the steam system are significant and that the environmental and economic gains to be obtained with improvement actions are quite significant. Based on the data and results suggest that future studies deem the continuity approach to steam generation systems, distribution and mainly condensate return.
