When simulating this, or any reactor in Chemcad, the units for the reactor may be set separately from the units for the rest of the simulation in the “more specifications” tab. The reaction units in Chemcad must be moles/reactor volume/time.
WebChemcad not calculating at all. No error either Hi all! I wanted to simulate a simple heat exchanger and an absorber column. So as you can see nothing fancy.
