100l hydrogenation reactor

Types of 100L hydrogenation reactors

A 100L hydrogenation reactor is a type of chemical reactor that enables hydrogenation reactions to occur. Hydrogenation is a process that involves adding hydrogen to something, usually unsaturated organic compounds like fatty acids. This process requires the use of specialized equipment and reactors known as hydrogenation reactors. There are three main types of hydrogenation reactors: batch reactors, semi-batch reactors, and continuous reactors.

• Batch hydrogenation reactors

  A batch hydrogenation reactor is a vessel where hydrogenation occurs in batches rather than continually. The batch hydrogenation reactor allows for the addition of reactants to the system and subsequent removal of products after the respective chemical reaction is completed. With a batch hydrogenation reactor, it's possible to change the reaction's conditions and parameters whenever a fresh batch of unsaturated organic compound is introduced to the system. This easily caters to different types of organic compounds. However, the drawback of a batch hydrogenation reactor is its low efficiency because it takes a long time for every phase of the process to occur, including filling, reaction, and emptying.

• Semi-batch hydrogenation reactors

  A semi-batch hydrogenation reactor is similar to a batch reactor, but reactants can be added to the system during the process of reaction. This continuous addition of fresh reactants while the reaction is still on-going helps to increase the reactant-to-product ratio. This, in turn, improves the overall efficiency of the hydrogenation reaction. Semi-batch hydrogenation reactors are also suitable for dealing with heterogeneous reactions.

• Continuous hydrogenation reactors

  A continuous hydrogenation reactor is a type of reactor where both the process of feeding reactants into the system and the production of products occurs continuously over a span of time. Continuous hydrogenation reactors make use of tubular or packed bed reactors. Continuous hydrogenation reactors are suitable for large-scale production of hydrogenated organic compounds.

Specifications and maintenance for 100L hydrogenation reactors

Specifications

• Volume: Hydrogenation reactors are usually categorized by volume. The 100L hydrogenation reactor means that it has a maximum capacity of 100 liters.
• Material : The materials used in hydrogenation reactors are usually chosen for their ability to withstand high temperatures and pressures, as well as their resistance to corrosion and chemical degradation. The 100l hydrogenation reactor is typically constructed from high-quality stainless steel, such as 304 or 316L stainless steel.316L stainless steel hydrogenation reactors are more resistant to corrosion, making them suitable for use in food, pharmaceutical, and chemical industries.316 stainless steel has higher strength and durability, making it more suitable for high-temperature and high-pressure environments.
• Structure: Tne 100L hydrogenation reactor has a base, a cylindrical vessel, a detachable top, and an agitator. The base provides stability and support. The cylindrical vessel is the main reaction chamber where the chemical process occurs. The detachable top facilitates the loading and unloading of materials, as well as maintenance and repair. The agitator is a critical component of the reactor that ensures thorough mixing of the reactants to enhance the reaction rate and uniformly distribute the heat and mass transfer within the reactor.
• Components: The hydrogenation reactor is equipped with various necessary parts. They include a pressure relief valve, a thermometer, a sampling valve, a pressure gauge, a water seal, and an air inlet. The pressure relief valve is designed for safety. It can prevent overpressure situations by relieving excess pressure from within the reactor. The temperature of the reactor is monitored and controlled by a thermometer. When operators need to check the internal contents or collect samples, they can use a sampling valve to do that. The pressure gauge indicates the pressure inside the reactor, which helps operators understand the operating conditions.

Maintenance

• Hydrogenation reaction:During hydrogenation, the characteristics of the material change, and the atom or group at the unsaturated bond transfers to the saturated bond. Heating up is one of the first steps. The temperature of the reactor is generally raised to 120-160 °C, and the pressure is increased to 1-5Mpa. When the hydrogenation reaction begins, the temperature and pressure are gradually adjusted as needed. It is essential to keep stirring constantly during the reaction to ensure sufficient contact and distribution of materials. The time of the reaction is generally 3-24 hours, depending on the actual situation.
• Repair hydrogenation reactor:Before repairing the hydrogenation reactor, it is crucial to ensure that the reactor has been thoroughly cleaned and that there are no materials or chemicals remaining inside. Next, turn off all power supplies and gas sources related to the reactor. Then, follow the manufacturer's instructions to enter the required maintenance mode. For those that need to be disassembled, carefully remove the external components, cover, and agitator of the reactor. After the maintenance is completed, double-check all the connections and ensure that there are no loose or wrong parts before restoring the power and gas supply.
