Abstract
In this study, the application of a natural gas cogeneration plant in mussel aquaculture farms is proposed with the objective of meeting electrical and thermal demands, specifically in the processes of declumping, washing, classification, pre-cooking, freezing, and packaging of the molluscs. Two scenarios were analyzed, the first one consisting of a natural gas cogeneration system integrated with a mechanical compression chiller, and the second one assisted by photovoltaic generation. The study was conducted considering real data collected at Cavalo Marinho farm, a producer of Perna perna mussels and Kappaphycus alvarezii macroalgae. Results obtained from simulations performed in the Engineering Equation Solver (EES) software confirm the technical viability of both scenarios. When subjected to economic evaluation based solely on electricity savings, the scenario assisted by photovoltaic energy shows a better return, on the order of 10 years or less assuming uninterrupted operation of the plant, including weekends. Considering the seasonality in mussel production, the surplus electricity can be commercialized with the potential for cost savings for the company.
