Could you help me figure this out? ASPEN Logistics uses a mixed steam of methanol and water as the input; after condensation, it is necessary to obtain data on the gas phase and liquid phase at the outlet. What module should be used and how should the inputs be entered to achieve this? Specifically, the total flow rate of water and methanol is 500 kg/h, the temperature is 130 degrees Celsius, and it is saturated steam; the mass ratio of water is 60% while that of methanol is 40%. After condensation, the temperature drops to 40 degrees Celsius. How should the flow rates of water and methanol in the gaseous phase after condensation, as well as those of methanol and water in the liquid phase, be simulated? Is there anyone experienced who can help with this simulation? Thank you!

For this operating condition, a spiral-wound heat exchanger is more suitable
