Constant reactor feed/withdrawal rate

An Example Varying Initiator Concentration at Constant Reactor Feed/Withdrawal Rate A more complete study of reaction kinetics, in terms of the relation between 2Fk, M, kVk, and [/] (see Chapters 1 and 16 for further discussion) could be made in a single experiment by changing initiator concentration at intervals. This represents a concise, economical means of determining reaction kinetics without the need to run several independent experiments. [Pg.279]

The analytical problems associated with differential reactors can be overcome by the use of the recirculation reactor. A simplified form, called a Schwab reactor, is described by Weisz and Prater . Boreskov.and other Russian workers have described a number of other modifications " . The recirculation reactor is equivalent kinetically to the well-stirred continuous reactor or backmix reactor , which is widely used for homogeneous liquid phase reactions. Fig. 28 illustrates the principle of this system. The reactor consists of a loop containing a volume of catalyst V and a circulating pump which can recycle gas at a much higher rate, G, than the constant feed and, withdrawal rates F. [Pg.231]

Formalism for Combined Reaction and Semibatch Flow The following summarizes the ACOMP approach presented in [38]. Expressions were derived for the concentration of monomer and polymer in the reactor, while reactions are occurring, when N solutes in solution are allowed to flow into the reactor, each at their own rate, which need not be constant, such that solute s has caused a change in reactor volume at time t of AVft), where Qft) is the instantaneous flow rate of liquid from a reservoir containing component s into the reactor. In the following, q is a constant withdrawal rate from the reactor q (ernes ) that feeds the ACOMP extraction/dilution/conditioning front end. [Pg.283]

Accordingly, the change in concentration (or in temperature) across the reactor can be made as small as desired by upping the recycle ratio. Eventually, the reac tor can become a differential unit with substantially constant temperature, while substantial differences will concurrently arise between the fresh feed inlet and the produc t withdrawal outlet. Such an operation is useful for obtaining experimental data for analysis of rate equations. [Pg.700]
