Process reactors are the heart of any chemical industry. They are used to conduct chemical reactions to transform raw materials into valuable products. Plug flow reactors are tubular vessels through which reactants or fluids (gases and liquids) flow at high velocities. Water at a controlled temperature circulates through the reactor to maintain constant reactant temperature.

Industrial reactors facilitate chemical reactions that produce new compounds or change the properties of existing materials. These vessels range in size from open kettles to elaborate tanks that are fitted with agitators, heaters and other accessories. Reactions are usually carried out in liquid or gas phases as they are easier to heat, cool and transport than solids. However, continuous reactors, such as those used in petroleum refineries and steel mills, are sometimes necessary for processes that require a steady stream of starting materials and intermittent discharges. When scaling up a PP fluidized bed, the superficial gas velocity strongly influences the fluidized regime and heat transfer. Therefore, conventional methods of scale up based on either weight space time or H/D similarity may not provide sufficient heat transfer similarity. Consequently, accurate prediction of PP buy reactors performance requires knowledge of the physical characteristics of the reactor and an appropriate model for reaction kinetics. Species balance, multi-component heat transfer and method of moments models are typically used to estimate these parameters.



Reactors range from small vessels the size of a desktop computer to vast structures like kilns that produce lime. Many chemical reactions require elevated operating pressure. Consequently, these reactors must be constructed from materials that can withstand the high operating pressure.

A tubular flow reactor consists of a tube or pipe through which reactants and products flow. These are the most common type of industrial process reactors. They can also have varying diameters along their length and may be horizontal or vertical. Reactors are categorized as batch or continuous depending on how they process samples, products and waste. Continuous process reactors are more efficient than batch reactors and can be operated for longer periods of time without shut-down. To prepare a reactor for operation, start by tightening the diagonally opposite screws on the split rings. Next, align the screw on the safety ring with the dent on the side of the split ring. Slowly tighten the pressure line going into the reactor until it reaches 1/3rd of its final required pressure.

A reactor uses different types of fuel depending on the type of chemical reaction it's performing. For example, a nuclear reactor will use metal rods that are inserted to control the fission process and then removed when it's done. For the most common types of industrial reactions, the fuel is a mix of chemicals that are put together in a vessel and then agitated to make them react and produce products. These types of reactions are called batch reactors. When the reaction is complete, the contents of the reactor are emptied for downstream processing and then cleaned, re-filled and re-inoculated so the process can start again.

Continuous process reactors are the opposite of batch reactors in that fresh media is continually added and reaction fluid continuously removed. They are sometimes referred to as tubular reactors, plug flow reactors and continuous stirred tank reactors (CSTR). They are the most complex type of reactors. These reactors typically require a high degree of agitation. For unbeatable deals on chemical reactors, click here or navigate to our official website.
