Chemical reactor - Wikipedia

The most common basic types of chemical reactors are tanks (where the reactants mix in the whole volume) and pipes or tubes (for laminar flow reactors and plug flow reactors) . Both types can be used as continuous reactors or batch reactors, and either may accommodate one or more solids (reagents, catalysts, or inert materials), but the reagents and products are typically fluids (liquids or .

A Beginner's Guide to Bioprocess Modes – Batch, Fed- Batch .

a batch, fed-batch or continuous bioprocess. In batch fermentation, microorganisms are inoculated to a fixed volume of medium in a fermentor. With microbial growth, the nutrients are gradually consumed and by-products accumulate. Therefore the culture environment is continuously changing. The broth is removed at the end of the run.

Transmission (mechanics) - Wikipedia

A transmission is a machine in a power transmission system, which provides controlled application of the power. Often the term 5 speed transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.. In British English, the term transmission refers to the whole drivetrain, including clutch .

Semi-Batch - Visual Encyclopedia of Chemical Engineering

Semi-batch reactors occupy a middle ground between batch and continuous reactors. They are open systems like CSTRs and run on an unsteady-state basis like batch reactors. They usually consist of a single stirred tank, similar to a batch reactor. The half-pipe coil jacketed reactor shown below can be used in semi-batch operations.

Continuous Stirred Tank Reactors - Visual Encyclopedia of .

An initial amount of cells are placed in the fibrous-bed basket. A nutrient rich medium is continuously fed into the reactor, and products are harvested. As the cells grow, they produce by-products, which are continuously removed from the reactor. The reactor below uses a pitched-blade impeller to continuously mix the reactants.

Chemical reactors - Essential Chemical Industry

Tubular reactors are used, for example, in the steam cracking of ethane, propane and butane and naphtha to produce alkenes. (b) Fixed bed reactors. A heterogeneous catalyst is used frequently in industry where gases flow through a solid catalyst (which is often in the form of small pellets to increase the surface area).It is often described as a fixed bed of catalyst (Figure 5).

Semibatch reactor - Wikipedia

Semibatch (semiflow) reactors operate much like batch reactors in that they take place in a single stirred tank with similar equipment. However, they are modified to allow reactant addition and/or product removal in time. A normal batch reactor is filled with reactants in a single stirred tank at time = and the reaction proceeds. A semibatch reactor, however, allows partial filling of .

Slurry Reactor - an overview | ScienceDirect Topics

Slurry reactors were developed to overcome the difficulties associated with the fixed-bed multitubular reactors. The first slurry reactor was commissioned by in 1993, with a diameter of 5 m and a height of 22 m (Figure 12-16) [48].In 1990, at Exxon, LA, a 1.2 m diameter, 21 m high slurry reactor with a production capacity of 200 bbl/day was developed [109].

Semi-Batch or Semi-Continuous Reactor - Process Operations

A semi-continuous reactor is a reactor for a multiphase reaction in which one phase flows continuously through a vessel containing a batch of another phase. The operation is thus unsteady-state with respect to the batch phase, and may be steady-state or unsteady-state with respect to the flowing phase, as in a fixed-bed catalytic reactor or a fixed bed gas-solid reactor respectively.
