Numerical Methods for Reactor Systems Design

In Chapter 3, the analytieal method of solving kinetie sehemes in a bateh system was eonsidered. Generally, industrial realistie sehemes are eomplex and obtaining analytieal solutions ean be very diffieult. Beeause this is often the ease for sueh systems as isothermal, eonstant volume bateh reaetors and semibateh systems, the designer must review an alternative to the analytieal teehnique, namely a numerieal method, to obtain a solution. Eor systems sueh as the bateh, semibateh, and plug flow reaetors, sets of simultaneous, first order ordinary differential equations are often neeessary to obtain die required solutions. Transient situations often arise in die ease of eontinuous flow stirred tank reaetors, and die use of numerieal teehniques is die most eonvenient and appropriate mediod. [Pg.279]

Equations 5-64, 5-65, and 5-66 are first order differential equations, whieh require initial or boundary eonditions. Eor the bateh reaetor, these are the initial eoneentrations of A, B, and C. In addition to the initial eoneentrations, the rate eonstants kj and kj are also required to simulate tlieir eoneentrations. The eoneentration profiles depend on die values of kj and kj (i.e, kj = kj, kj kj, kj kj). Assume dial at die beginning of die bateh proeess, at time t = 0, =1-0 mol/m, and [Pg.281]
