Abstract: In this study, a new environmentally friendly polygeneration scheme is proposed in arrangement with a gas turbine cycle. In order to investigate the proposed system, parametric research is conducted in conjunction with the energy, exergy, economic, and environmental assessments (4E study). The simulation is done in the Aspen HYSYS software. According to the design condition results, the total energy efficiency and exergy efficiency, thermoeconomic indicators such as total unit cost of product and total product cost, as well as the waste heat recovery ratio in the heat exchanger network of the evaporator, are 57.81 %, 63.47 %, 25.12 $/GJ, 0.1019 $/kWh, and 49.67 %, respectively. In addition, it is determined that the total exergy destruction rate and the exergy destruction intensity for the proposed process are 204470 kW and 1.33 kWD/KWP, respectively. The gas turbine cycle with a share of 60 %, exhibits the highest irreversibility. Based on economic estimates, the project requires a total investment of $636209804. In addition, considering an annual income of 159850224 $, the payback period is 3.98 years. Lastly, the environmental evaluation indicates that the proposed process has a carbon footprint equal to 0.356 kgCO2/kWh and a total carbon dioxide emission of 67241.36 kg/h.
