Análise de dimensionamento do trocador de calor a placas da sala de envase de uma indústria de bebidas gaseificadas

Abstract

The efficiency of a process encompasses various variables within it, regardless of the final product offered, including thermal efficiency. Therefore, this study specifically aims to analyze the heat exchanger in the bottling room of a carbonated beverage industry, which does not meet the plant's demand. Initially, based on the data collected from the process and those measured experimentally, it was possible to estimate the quantity of plates and the necessary actions on the plate heat exchanger so that it could supply the process demand. The study initially pointed out the high exit temperature of the final beverage in the heat exchanger, directly affecting its carbonation efficiency, and exposing the real operation of the thermal exchange equipment present. Three scenarios were analyzed for the calculations, which include resizing the equipment project shown by the supplier, the same action for the project using the real values of the fluids involved, and finally, demonstrating how the heat exchanger behaves in reality. In these, with analyses made according to the methodology approached, it was concluded that the equipment under analysis is undersized, presenting 38 plates less than the sizing and a thermal exchange area 10% smaller than ideal. Therefore, maintenance and alteration of the same were proposed so that it could provide the ideal conditions for the plant's demand. Finally, a financial study was conducted, which raised the cost of the actions proposed by this work, resulting in an investment of R$ 1351.30 reais.
