where HD is the heat duty which depends on scaling requirement capable of producing up to 10 MW. Equation (6) assumes a design pressure for the tubes of 5 MPa and construction from stainless steel 316. All effluent stream temperatures are obtained from the process simulation results using Aspen Plus.
3.4. Flash drum and decanter
The design of the flash drum and decanter is based on a completed design of the pressure vessel to obtain the vessel weight, volume, and a fixed residence time (τ) to be achieved at medium pressure (in the range of operating pressure from 3 to 5 MPa). The volumetric flowrate (View the MathML source), m3 s−1, of the input streams is obtained from Aspen Plus, and the vessel volume (V), m3, is formulated using the following equation:
