Simply take latent heats of methanol & water and calculate condensing load - Convert it to TR of refrigeration - Add process losses ~20% in 0°C chilling system. Find out steam requirement by thumb rule of 10 Kg/TR & U will get the no.
I dont know what is flash condensation.

hai technologist,
flash condensation is nothing but flash separation, here it was condensing so i wrote flash condensation. this work i had done in aspen plus.
condensing load means just calculation of sensible entalphies right? if not please elucidate me. thanking you for spending your valuable time.

Condensing load means latent heat of condensation which is much larger than sensible heat.
I could not understand flash condensation.
U r getting vapors of methanol & water from your pervaporation unit. So how can U flash vapors. Is it by pressure change or temp change.

hai technologist,
ok, its not flash, it is fractional condensation, by decreasing from 280k - 278 k , by that some of the water and methanol condenses as liquid. that liquid had distillation done and it was made to 98 wt%
