In industrial chemical processes, a reactor is used to transform cheap raw materials into valuable products. This requires a number of functions including bringing the reactants together in intimate contact, providing the right environment (temperature and concentration fields, catalysts), and separating the product.

Moreover, you must maintain these chemical reactors on a regular basis to ensure that they are in the best working conditions. This will improve their longevity or service life and performance.

Reactors for Sale

If you are looking for a good deal on chemical glass reactors, you should shop around to find the best prices. This will save you money and ensure that you are getting the best value for your investment. The size and type of reactor that you choose will depend on the process that you are performing. It is important to make sure that the reactor is designed for your specific process.

There are many different types of reactors for sale  available, but the most common are batch reactors. These are used for a variety of applications, including biochemical reactions and small-scale production. They are typically made from glass or stainless steel. Some are also available with a jacket that allows liquids to be cooled or heated.

Another popular type of reactor is a continuous stirred tank reactor (CSTR). These are used for larger-scale production, such as in the oil industry. They are used to produce crude oil and other fuels. They are also used in manufacturing a wide variety of chemicals.

Aaron Equipment carries a large inventory of used reactor vessels from various manufacturers and sizes. These vessels are available in carbon, alloy, glass lined and stainless steel construction with jacket & shell pressure ratings from 50 to 275 psig, volume capacities of up to 4000 gal., agitated reactor styles & more.

Chemical Reactors

Chemical reactors are machines used to facilitate the reaction of various chemicals. They are designed to maximize net present value of the given reaction and ensure that it proceeds with the highest efficiency towards the desired output product. This is achieved by minimizing energy input and energy removal expenses. These expenses can be in the form of heating or cooling energy, pumping to increase pressure, frictional pressure loss (such as through an orifice plate), and agitation.

These chemical reactors can be of a continuous or batch design. In a batch reactor, the reactants are fed into a closed vessel with an agitator. The agitator then mixes the reactants thoroughly to allow them to react together efficiently. This type of reactor is useful when the reaction is exothermic. In a semi-batch reactor, the reactants are loaded into the reactor all at once initially, but the other reactant is then added continuously after specific time intervals.

There are also tubular reactors that contain a catalyst bed, which is often made of solid particles. The reactants are then pumped through the catalyst bed to create a gaseous or liquid state. In addition, there are a number of microreactors that are small enough to be handheld and can be used for reactions in laboratory settings. buy reactors from the best reputable seller like surplusrecord.

To ensure that chemical reactors perform at their best, they need to be properly maintained. This includes regular cleaning and lubrication of moving parts. In addition, chemical reactors must be operated by trained personnel who know how to operate and maintain them.

Laboratory Reactors

Laboratory reactors offer scientists the ability to generate more information per experiment, increasing productivity in chemical and pharmaceutical development. Automated lab reactor systems allow researchers to run a set of experiments unattended around the clock, record and analyze results, and instantly share them with others. Process Analytical Technology (PAT) instruments track critical process parameters to support Quality by Design (QbD) requirements. Particle size analysis enables researchers to optimize solid and liquid formulations based on particle and droplet size, while in-situ FTIR and Raman spectrometers measure vibrational properties of molecules for real-time chemical reaction monitoring.

A variation on the differential reactor is the integral reactor, which features a catalyst bed contained in paddle screens. The fluid inlet and exiting product stream pass through the catalyst bed at roughly the same rate. This arrangement helps to keep the gas-catalyst contact time constant, and it also prevents channeling of reactant from one reaction path to another. However, the complexities of containing the catalyst particles in the paddle screens can make it difficult to achieve isothermal conditions and maintain proper agitation. Consequently, it receives only a fair rating in the ease-of-construction category.

Flow chemistry platforms allow researchers to conduct traditional nitration, oxidation and photocycloaddition reactions at smaller volumes than are possible with batch reactors. They can be integrated with other analytical equipment, such as reaction calorimeters and in-situ FTIR and raman spectrometers.

UV Reactors

In chemical engineering, reactors are vessels designed to contain a chemical reaction. They can be simple open kettles or elaborate vessels with jackets or internal coils for heating and cooling, nozzles or ports for adding and removing materials, sources of heat, electricity or light, agitators and strong walls for operation at high pressures.

The residence time in batch reactors can be controlled by feeding the material at a constant rate. This allows for more consistent quality of the final product. However, it’s more difficult to control the residence time of a continuous reactor since it continuously adds and removes reactants.

UV reactors can be installed in the clearwell, or downstream of the filter gallery (Figure below). Installation after the high service pumps is the least desirable option as it increases the risk of water hammer damaging the lamp sleeves and possibly the lamps themselves. In addition, the higher headloss of a downstream installation causes more stress on the UV system and may require an increase in the number of reactors per pump station or more aggressive wattage/dosage strategies.

UV system maintenance is important to ensure continual operation within desired operational, validation and disinfection parameters. This includes monitoring of UVT and UV intensity sensors and a routine wiping of the lamp sleeves. It is also recommended to keep a log of all alarms and shutdowns in order to record system performance and determine the potential cause.
