Used Reactors
Choosing the right type of reactor depends on the specific application. reactors for sale are used in a variety of industries such as chemical, polymer, dyes and pigments, pharmaceuticals, paper and pulp, and aerospace and semiconductor manufacturing. They are a vital part of the overall manufacturing process and offer multiple benefits to end users. For example, chemical reaction engineering uses reactors to ensure that a desired reaction is maximized with the least amount of energy input. This can result in reduced raw material costs, production time, and labor.
Chemical reactors are typically made of robust stainless steel and come in a wide range of sizes, pressure, and temperature specifications. They are also available in continuous or batch operation, and can accommodate solids, fluids, or gases. Reactors are characterized by their ability to control the rate of reaction by changing the temperature, pressure, and flow.
Reactions can be either thermochemical or chemical, and the reactor is designed to maximize net present value of the reaction. Reactors are a key piece of equipment for producing specialty compounds like catalysts, surfactants, and biochemicals. buy reactors from the best seller surplusrecord.
Nuclear reactors generate power through nuclear fission. The primary cooling system consists of a heavy water (deuterium oxide or tritium) that flows through the reactor core, moderator, and surrounding tubes. The coolant is then used to produce steam for the turbines in a secondary circuit. This design, known as a Pressurized Water Reactor or PWR, is the most common in the United States and is usually located in an underground concrete or steel vessel. The CANDU and RBMK designs use pressure tubes, rather than a large pressure vessel enclosing the reactor core, and can be refuelled progressively without shutting down by disconnecting individual tubes.
Chemical Reactors
Chemical reactors are a type of vessel used in industrial processing to transform feedstocks into end products. They are designed to control conditions such as temperature, pressure, and the rate of reactions. They also come equipped with sensors to monitor reaction parameters and to alert the operator if problems occur.
They can be used in a variety of applications, including smelting, gasification, and distillation. They are typically made of stainless steel or other materials that can withstand high temperatures and pressures. They can be either continuous or batch. Batch reactors are used to mix reactants and release the final product at a predetermined time. Continuous stirred tank reactors, on the other hand, maintain a continuous reaction with no fixed time to completion.
In recent years, engineers have developed new chemical reactors that are more efficient than conventional models. For example, some use baffles to oscillate the fluids to be reacted in a similar fashion as plug flow reactors. This can result in improved mixing and higher yields.
Reactions in chemical reactors can be either homogenous (the catalyst is in the same phase as the reagents) or heterogeneous. Catalysts are often metals, such as platinum or palladium, but they can also be a biological material such as enzymes, which are proteins. Most chemical reactions are homogeneous, but some processes need to be carried out in a heterogeneous environment, such as oxidation or hydrogenation.
Industrial Reactors
Industrial reactors are at the heart of chemical processing, converting feedstocks into finished products. These large vessels can be found in the polymer, dyes and pigment industries, pharmaceutical, aerospace and semiconductor industries and many more. In fact, the industrial reactors are considered to be a critical equipment for any type of chemical industry.
Reactions in industrial reactors can be either batch or continuous processes. The key distinction is that batch processes operate in a transient state, with the key process variables changing over time, whereas continuous systems are run at steady-state. Choosing the right type of reactor for a given reaction requires detailed knowledge of the thermodynamics and kinetics involved in the chemical reaction.
During the process of selecting a suitable type of reactor for a particular application, several factors must be taken into account, including the temperature range of the reaction, the required product yields and the production capacity of the reactor. Reaction enthalpies, phase-equilibrium constants, heat transfer coefficients and reaction rate constants are all important parameters that must be determined prior to the design of the reactor (Towler and Sinnott, 2013).
The choice between a batch or continuous process will also have an impact on capital and operating costs. For example, batch processes are more expensive than continuous operations, because they require more manpower to charge and discharge the reactors, clean the blades and perform other tasks. Continuous reactors, on the other hand, are easier to scale up and can be operated for a longer period of time before they need to be refilled with raw materials.
