Abstract
The pump is one of the main components of the Organic Rankine Cycle (ORC), responsible for circulating the working fluid, which in this design is refrigerant-600a. The mathematical design of this pump begins by inputting initial data on the brine used as the heating fluid in the ORC. This data was obtained by simulating a pump in a Rankine cycle system, resulting in a temperature of 176°C, a pressure of 9.65 bar, and a flow rate of 159,210.92 kg/h. The main design requirement is that the total head and NPSH (Net Positive Suction Head) required must not exceed the NPSH available. The magnitudes of these parameters are 6.00 m and 2.71 m, respectively. Next, the core components of the pump, namely the impeller, casing, and shaft, are designed, and the materials chosen for these components are adjusted according to standardization requirements. Based on the mathematical design results, it was found that the pump operates at a pressure of 6.8 bar on the suction side and 9.5 bar on the discharge side with a capacity of 2.68 kg/s, a pump head of 54 m, and a total of 6 blades. The pump is designed to operate at 1500 rpm with a power of 17.30 kW and a pump efficiency of 80%.
