Reactor mass balance error chemcad
WebReactor Volume Equation 4.5 applies whether the reactor volume is constant or changes during the reaction. If the reactor volume is constant (liquid-phase reactions) dc j dt = R j (4.6) Use Equation 4.5 rather than Equation 4.6 if the reactor volume changes signi cantly during the course of the reaction. 7/152 Analytical Solutions for Simple ... 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. I input the required datas for example in the HE Stream 1: Water, 90 degree celsius, 500 kg/h. In the HE strem 2 temperature 20 degree celsius.
