Summary: The multi-stage flash brine recirculation (MSF-BR) system of the Abadan refinery is investigated in this study from energy-exergy-exergoeconomic viewpoints. The effects of top brine temperature, number of stages, and ambient temperature on the system performance are evaluated. The results show that increasing top brine temperature improves exergy efficiency, gained output ratio, and distillate water production. However, increasing the number of stages in the heat rejection section decreases the gained output ratio. It is also found that there is a significant cost difference with an increase in the number of stages. Finally, it is concluded that utilizing waste heat from the refinery complex for the desalination system can lead to cost savings in energy consumption and CO2 emissions.

Summary: This study investigates the technical-economic performance of a gas-fired power plant with a simulated carbon capture unit in an oil refinery. The current condition of the power plant is analyzed using mathematical relations and software, and a post-combustion method is used to simulate the carbon capture unit. The use of exhaust steam from the deaerator as required steam helps reduce utility consumption, and changes in the unit pressure profile, removal of a pump, and initial investment result in reduced operating costs. The Carbon Capture unit effectively reduces carbon dioxide emissions from 138.06 to 1.51 million tons/year, but it also decreases efficiency from 76.282 to 60.480% due to electricity consumption. The study suggests using excess steam from the power plant as a heat source to increase overall efficiency, leading to a potential increase in efficiency from 60.480 to 71.639%.
