The purpose is just to dry coal..common sense tell me that water will evaporate at 100 C at 1 atm. I set higher because moisture is trapped in pores of the coal, the liquid trapped in small pores usually will have lower vapor pressure (capillary condensation or Kelvin equation) so setting a higher temperature might be a good idea. Anyway, this are all just based on a quick estimate. A good way to know would be to experimentally determine water removal. Using TGA analysis would definitely help to determine water removal from coal sample
@10:00 because the stoichiometric coefficients must be in molar basis.
very good explanation.
where did you get the value 0.900764 for h20

hi i have nonconventional solid how to define the Stoichiometric coefficients for drying
Is there any reason behind that you selected dryer to operate at 120ºC? Thank you
