Gassing Stirrer

Our gas supplying stirrer has unique design. The gas input and saturation of the medium are faster than with conventional stirring systems. This results in considerably shorter reaction times in heterogeneous catalysis. This effect is further enhanced by a possible baffle. Hinder the 45-grid bevels of the propeller, a vacuum is created when the propeller rotates clockwise. This vacuum creates enormous suction power. Accordingly, the gas is quickly brought out of the gas chamber via the hollow shaft into the medium.

Various process equipment accessories are possible to meet process specification requirement. Eg. control valves, metering valves, safety valves, fittings, regulators, tubes, hoses, sampling system, spargers, catalyst basket etc. contact us to choose the right accessories for your specific process requirement.

Frequently Asked Questions

What is a pressure reactor? +
A pressure reactor is a type of vessel that is tightly sealed to allow safe experimentation in chemical reactions above ambient pressure and temperature. Pressure reactors allow researchers (and industry) to experiment with reactions that do not usually occur at normal pressure and temperature and to have more precise control over the parameters of the reaction. This may include processes such as catalytic reactions, polymerization, or structural testing of materials.
What is a hydrogenation reactor used for? +
A hydrogenation reactor is an example of a pressure reactor designed specifically for reactions where hydrogen gas is introduced into the system to modify or stabilize a compound. The hydrogenation reactor is set up to provide controlled high-pressure conditions, which allow efficient hydrogen absorption into the reaction medium and maximize catalytic performance. Hydrogenation reactors in various forms are used widely in pharmaceuticals, petrochemicals, food processing, and in the production of speciality chemicals.
How does a high-pressure reactor work? +
High-pressure reactors are designed to hold elevated pressure inside the vessel due to the structure of the sealing. The construction of the reactor is able to withstand extreme internal conditions. High-pressure reactors are designed to permit chemical reactions requiring additional reaction energy or gas–liquid interaction. A high-pressure reactor, under the specified conditions of temperature, pressure, and mixing, allows for highly controllable synthesis, testing, and catalytic experiments to be performed either in laboratories or industrial settings.
What is the difference between a high-pressure reactor and a high-pressure autoclave reactor? +
A high-pressure reactor is a general type of vessel designed for reactions under elevated pressure, while a high-pressure autoclave reactor also has advanced safety systems, improved insulation at elevated temperatures, and more precise instruments for controlling the internal parameters of the reaction. Autoclave reactors are designed for more demanding applications where more durability, automation, and reliability can be beneficial in optimizing experimental conditions for extreme reaction environments.
What is a high-pressure reactor vessel made of? +
A high-pressure reactor vessel is generally constructed using robust materials such as stainless steel, Hastelloy, and other specialized alloys that are resistant to chemicals. These materials can withstand harsh chemicals, extreme temperatures, and substantial pressure. The structural integrity of these materials will provide structural safety, reliability, and chemical compatibility for a variety of experimental and industrial conditions.
When should a high-pressure glass reactor be used? +
If it is important to visually monitor the reaction, then a high-pressure glass reactor vessel is the perfect option. A high-pressure glass reactor will enable a researcher to see colour changes, mixing behaviour, and other reaction development without removing the lid. High- pressure glass reactor vessels are often used in laboratory settings and allow work with sensitive chemical processes where chemical compatibility and visibility of conditions are crucial.
What are the applications of a high-pressure lab reactor? +
A high-pressure lab reactor vessel is used when researching small-scale projects that might involve hydrogenation, catalyst development, polymer synthesis, or materials testing. It allows the researcher to maintain control over the reaction parameters, making it suitable for testing new processes before extensive use. A high-pressure lab reactor may also be used to facilitate industrial conditions in a safe, compact laboratory system.
Are high-pressure reactors safe to use? +
High-pressure reactor vessels can be safe if operated appropriately and equipped with the proper safety accessories and components, including, but not limited to, pressure relief valves and rupture discs, temperature controls, and/or alarms. Appropriate maintenance and personnel training will reduce risks and potential incidents. Following the manufacturer’s suggestions for commonly used rail components will provide confidence to know that the system can run in elevated pressure ranges without compromising user safety or the reliability of the means to operate.
How do I choose the right pressure reactor for my application? +
Selecting a pressure reactor depends upon the pressures needed, the limits of temperature, the types of reaction you are doing, and the compatibility of materials. You should also consider whether you need something specific, like a high-pressure glass reactor, a hydrogenation reactor, or a high-pressure autoclave reactor. Each type of reactor will fit well into a specific process, and using the right design will lead to the most efficient and safe operation with satisfactory performance.
What maintenance does a high-pressure reactor require? +
A high-pressure reactor also requires routine maintenance. You will want to routinely check gaskets, seals, gauges, and safety valves to ensure that they are all working properly. Cleaning the vessel after use minimizes contamination and corrosion from previous examples. Routine checks of internal surfaces of the reactor, lubrication of moving parts, and checking the operation of the pressure control components also help the life of the reactor and keep it operating safely.
