Document Summary

One input may be controlled whereas the second one may be considered as a disturbance (measured or unmeasured). Table 3. 5. 1 p. 80 : rules of block diagram algebra. Chemical reactors do not behave like other chemical processes. Conservation of mass is not sufficient to model chemical reactors. Besides, the total number of moles is not necessarily conservative concept. of. Rate of component i out of the reactor of. 3moles are not equal to 4 moles: combustion reaction: Note that oxygen moles are split between the formation of. No moles of ch4 in the product. To simulate the reactor behavior, one should take into account the rate of reaction in both molar flow and energy balances. of. Rate of component i out of the reactor. Rate of production or disappeara nce of component i. In reaction a, taking a as the key component, the rate of reaction is: V dn j dt (j= a or b) f is the molar flow.
