sodium acetate in a batch and in a continuous stirred tank reactor‚ we can evaluate the rate data needed to design a production scale reactor. A stirred tank reactor (STR) may be operated either as a batch reactor or as a steady state flow reactor (CSTR). The key or main feature of this reactor is that mixing is complete so that properties such as temperature and concentration of the reaction mixture are uniform in all parts of the vessel. Material balance of a general chemical reaction described

ABSTRACT In this experiment‚ our objectives are to examine the effect in a tubular flow reactor and to construct a residence time distribution (RDT) for both pulse input and step change. The first experiment is the effect of pulse input in a tubular flow reactor. Before the experiment was done‚ we need to do some general start-up process in order to get a better result and to avoid errors during experiment. After that‚ a constant flow rate was set up at about 700 ml/min. After that‚ both of the

A continuous stirred tank reactor (CSTR) is a continuous reactor that runs at a steady state. They are used most frequently with liquid phases‚ but can handle gas or solid reactions as well. No matter what the reactants are or the product is‚ all CSTR ’s have the same components. There is an inlet stream(s) that bring all of the reactants in at a particular rate. This stream(s) dumps into a large container; there is a shaft with a blade attached (stirrer) in the reactor that rotates around to mix
