A gasification, power generation and desalination solution have been designed using açaí crops waste of Ilha das Cinzas production community, from Gurupá/PA aiming to reduce the inappropriate disposal of the seeds that in average are 79 percent in mass of the fruit. A thermal balance of the gasification process has been developed to determine the gas energy produced from the biomass, achieving a lower heating value of 3,05 MJ/Nm3 for the syngas and 14,16 MJ/kg for the biomass. The solution aims the production of natural gas with average composition of 10,3 percent of CO, 12 percente of h(cifrão), 1,35 percent of CH percent e 55,23 percent of n(cifrão) being used as a fuel for an internal combustion engine connected to an electric generator of 45 kW nominal power, achieving 26 kW operating with the proposed fuel in full load. The power produced is sufficient to meet the local demand of açaí crops within the community with a thermochemical biomass conversion efficiency of 12 percent. Reusing the thermal energy from the exhaust gases from the engine, a desalination plant was designed to evaporate the water from Rio Amazonas estuary to produce drinking water for the isolated community, with the heat exchangers being designed from the global coefficient of heat exchange and the heat transfer area for the evaporator (A(= 0,6 m2 e U = 400 W/m2.K) and for the condenser (A) = 0,9 m2 e U = 400 W/m2.K). Moreover, the thermal power exchanged within the heat exchangers has been specified: 31 kW for the evaporator and 27 kW for the condenser. Given the minimum operating conditions being set for 1,6 kg/h of biomass for gasification and power generation, the viable periods for application of the proposal was set for both the harvest and off-season crops time through the storage of seeds during the surplus of production.
