It is assumed of having no spatial variation in concentration and temperature. As name implies the reactor is well mixed, allowing the assumption of same concentration at any point within the reactor and the product. A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state ( Q in = Q out = Q ). The main assumption in this case is that the concentration of the incoming fluid will become CSTR reactors are batch reactors with an open systems and have impeller equipped with it to provide agitation for proper mixing or reactor content.

A CSTR has some of the same characteristics as a batch reactor: its contents can be well mixed and Continuous stirred tank reactor system (CSTR) is a typical chemical reactor system with complex nonlinear characteristics. The system consists of two tanks as illustrated in Figure 1. The concentration of the outlet flow of two chemical reactors will be forced to have a specified response.

The In this example, the startup phase of a continuous stirred tank reactor (CSTR) used to produce propylene glycol is investigated. The non-isothermal process is A CSTR is normally used for a homogeneous liquid-phase reaction. In the laboratory, it may also be used for a gas-phase reaction for experimental measurements This brief paper demonstrates the concept of linear feedback equivalence for an exothermic eontinu-ous stirred tank reactor with first order kinetics. Feedback The system under consideration is a Continuous Stirred Tank Reactor (CSTR) in which a non-isothermal, irreversible first order reaction. A ¡!

Based on Figure, reactor 1 is the closest to ideal CSTR since the curve flow decreases over time compared to bell shape curve for reactor 2 and reactor 3.However, throughout the curves values, E (t) curve for Reactor 2 shows the highest value which signifies the higher rate of mixing compared to the other two reactors.The first moment to be considered in the Residence Time Distribution (RTD) function is the mean residence time, tm. In a CSTR, one or more fluid reagents are introduced into a tank reactor which is typically stirred with an impeller to ensure proper mixing of the reagents while the reactor effluent is removed. Dividing the volume of the tank by the average volumetric flow rate through the tank gives the space time , or the time required to process one reactor volume of fluid. Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.
