What is a high pressure reactor?
A high-pressure reactor is a chemical reaction vessel that can perform a reaction under pressure. The pressure may be caused by the reaction in the reactor, or it may be generated by an external source, such as hydrogen in catalytic transfer hydrogenation. A reactor can be used to facilitate the reaction of samples with hydrogen, carbon dioxide, and acetylene.
A pressure reactor offers several advantages over the conventional round bottom flask. First, it can carry out a reaction above the boiling point of a solvent. In addition, pressure can reduce the reaction volume, including the liquid phase, increase the concentration and collision frequency, and accelerate a reaction.
Scientists typically use glass pressure reactors when an operator needs to observe the progress of a reaction. Although these systems’ pressure ratings are generally lower than most metallic systems, they are still efficient devices for achieving the responsible pressure limits.
The ratings are directly related to the diameter of the vessel - the larger the diameter, the lower the allowable pressure. Integral bottom valves can affect pressure ratings. A bottom valve on a glass vessel may result in lower allowable working pressure. These are all variables that depend on the process and parameters of the particular reaction.
Metal pressure reactors are typically used for high-pressure reactions. They have a much higher pressure rating compared to glass reactors. Although these reactors have a higher pressure rating, they have significant disadvantages. One of them is that metal vessels are more susceptible to corrosion.
When buying a high-pressure reactor, the most important thing is to find a reliable vendor. With years of experience, Amar Equipment is an accredited provider that can design, manufacture and supply high pressure/temperature batch and continuous reactors or related systems.
Standard glass pressure reactor
Glass Pressure reactors are typically used when an operator needs to observe how a reaction takes place. Although the pressure ratings on these systems are lower than most metal pressure reactors, they are still an efficient set up for reaching responsible pressure limits. The ratings on glass vessels are directly related to the diameter of the vessel. The larger the diameter, the lower the allowable pressure. Integrated bottom valves can also impact the pressure ratings. A bottom valve on a glass vessel typically relates to a lower allowable working pressure. These are all variables determined by the process and parameters of each individual reaction. Glass pressure vessels can also be used in inert applications. These vessels are used in reactions included but are not limited to Hydrogenations, Polymerizations, Synthesis, Catalytic, petrochemical, crystallization, and so on.
One of the drawbacks of a standard glass pressure reactor is the potential explosions due to hard-to-predict excessive internal pressure and lack of relief mechanism. However, with proper safety implementation provided by the manufacturer, the operator can perform most reactions in a safe manner.
