Chemical reactor - Infogalactic: the planetary knowledge core

In a CSTR, one or more fluid reagents are introduced into a tank reactor (typically) equipped with an impeller while the reactor effluent is removed. The impeller stirs the reagents to ensure proper mixing.Simply dividing the volume of the tank by the average volumetric flow rate through the tank gives the residence time, or the average amount of time a discrete quantity of reagent spends .

Continuous stirred-tank reactor - Wikipedia

The continuous stirred-tank reactor (CSTR), also known as vat-or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a .

Biological and Chemical Reactor Control Opportunities

The residence time for a CSTR is the volume divided by the total flow of feeds. For a batch reactor, the residence time is the cycle time. In a CSTR some of the reactants appear in the discharge within one turn over time, which in general is less than 1/20 of the residence time. The amount of time spent in the

Continuous reactor - Wikipedia

Continuous reactors (alternatively referred to as flow reactors) carry material as a flowing stream.Reactants are continuously fed into the reactor and emerge as continuous stream of product. Continuous reactors are used for a wide variety of chemical and biological processes within the food, chemical and pharmaceutical industries. A survey of the continuous reactor market will throw up a .

Chemical reactor - Wikipedia

A chemical reactor is an enclosed volume in which a chemical reaction takes place. 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. The design of a chemical reactor deals with multiple aspects of chemical engineering.
