Abstract
Microalgae culture has been used to obtain biomass to produced biofuels and other bio-products, such as antioxidants and food. Since microalgae are photosynthetic beings, the culture has also recently been used for mitigation of industrial flues gases due to the its higher composition of carbon dioxide that are important for the microalgae metabolism. However, industrial flue gases cannot be injected direct into the culture because of it high temperature. Reducing the temperature of flue gases are then necessary to avoid microalgae injury and, consequently, biomass loss. To reduce the temperature, shell and tube heat exchangers are commonly used because of its cost benefit and its ease of manufacturing. This work brings a modelling and simulation of a shell and tube heat exchanger of a single pass that is used to reduce the temperature of flue gases from an electric generator of 50 kVA power. The modelling and simulation were performed in Fortran code using the finite volume method where the results obtained by simulation where compared to the real data after the heat exchanger installation. The simulation results and the real data obtained for the refrigerating fluid had a variation of only 0.84% while the simulation results and the real data for the final temperature of the flue gases had a variation of 1.67%.
