Equipment selection and key assumptions and key sizing parameters applied for cost estimation.
| Equipment | Basis | Key sizing parameter |
|---|---|---|
| Pumps | Centrifugal API-610 BB3/BB5 pump type. Assumed isentropic efficiency adding 3% for friction losses and estimated losses in e-motor. | Pump power (kW) |
| Heat exchangers in condensing service | Air Cooled Heat Exchanger (refrigerant condenser) or Shell & Tube with U = 1000 W/m2 K. | Heat transfer surface area (m2) from LMTD, U-value and heat duty (kW) |
| Compressor | Centrifugal type with assumed isentropic efficiency adding 3% for friction losses and estimated losses in e-motor. | Compressor duty (kW) |
| Heat exchangers in gas service | Air Cooled Heat Exchanger or Shell & Tube with U = 500 W/m2 K. | Heat transfer surface area (m2) from MTD/LMTD, U-value and heat duty (kW) |
| Compressor suction scrubber | Dimensioning using GPSA method [33]. The diameter is estimated from a K-value of 0.1 m/s. Vessel wall thickness is estimated using ASME BPVC [34] and selected material properties. Vessel weight is estimated on shell and ends adding 30% for supports and nozzles. | Gas volumetric flow, pressure and gas density |
