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  

In a continuous-flow stirred-tank reactor (CSTR), reactants and products are continuously added and withdrawn. In practice, mechanical or hydraulic agitation is required to achieve uniform composition and temperature, a choice strongly influenced by process considerations.

The continuous stirred tank reactor (CSTR, or simply the stirred tank reactor, STR) is essentially similar to the batch reactor, with the main important difference is that, for the stirred tank reactor, provision must be made for continuous flow of material into and out Continuous-Stirred Tank Reactor (CSTR) CSTR is commonly used for industrial production. It is assumed of having no spatial variation in concentration and temperature.

A Continuous Flow Stirred Tank Reactor (CFSTR) is one in which the contents are stirred so uniformly that it is assumed that no variation or concentration

In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. Reactor Analysis---the CSTR Reactor Analysis refers to the use of mass balances to analyze pollutant concentrations in a control volume which is a chemical reactor.

Two tanks in series. The output of the first tank is the input of the second tank.

wastewater treatment. Two common hydraulic models of bioreactors are the continuous stirred tank reactor (CSTR) and the plug-flow reactor (PFR). LÄS MER 

The cylinder-shaped inner chamber has a diameter of 18 mm and a depth of 10 mm. REAKTOR CSTR Adalah reaktor di mana isinya diaduk dengan baik dan seragam maka, fluida yang di alirkan keluar dari reaktor ini memiliki komposisi yang sama dengan fluida di dalam reactor. Reaktor CSTR dijalankan secara kontinyu dan juga biasa digunakan untuk reaksi yang berlangsung dalam satu fase saja.
