Chemical reactors - Essential Chemical Industry

Batch reactors. Batch reactors are used for most of the reactions carried out in a laboratory. The reactants are placed in a test-tube, flask or beaker. They are mixed together, often heated for the reaction to take place and are then cooled. The products are poured out and, if necessary, purified. . Continuous stirred tank reactors, CSTR.

Batch and Continuous Bioreactors | Protocol

Similar to batch reactors, continuous stirred tank reactors, sometimes called chemostats, require their individual components to be rinsed thoroughly with deionized water before assembly. Once cleaned, the stirrer assembly and drive shaft components are fitted together, and the reactor vessel filled with deionized water to improve sterilization .

Batch Reactor - an overview | ScienceDirect Topics

An advantage of batch over continuous stirred–tank and tubular reactors is that a single experiment with samples taken at frequent intervals in effect scans the entire conversion range. A disadvantage is that samples must be taken from the reactor itself. For elucidation of mechanisms, rate data at very low conversions may be highly desirable.

Continuous Stirred Tank Reactors - Chemical Engineering

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.

Continuous stirred-tank reactor - Wikipedia

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, 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 specified output.

Continuous reactor - Wikipedia

Reactors can be divided into two broad categories, batch reactors and continuous reactors. Batch reactors are stirred tanks sufficiently large to handle the full inventory of a complete batch cycle. In some cases, batch reactors may be operated in semi batch mode where one chemical is charged to the vessel and a second chemical is added slowly.
