What’s The Difference Between Thermal Oxidizers And Catalytic Oxidizers?

When certain products are manufactured in industries, harmful pollutants are generated and spread into the surrounding atmosphere. These harmful toxins called VOCs (volatile organic compounds) have adverse impact on our ecosystem, which is why environment agencies have implemented the emission rules in past years. These days, most of the companies install VOC emission control system, also known as VOC abatement products to adhere to the environmental regulations.

Different types of Oxidizers used in industries

VOC concentration systems have been used in industries as the facility to treat hazardous waste for more than 25 years. Further, there are many factors that can impact the design, engineering, operating efficiency, resources and operating costs of pollution abatement systems in industries. There are different types of oxidizers that are used in industries based on their specifications. While VOC thermal oxidizer offers the traditional way of VOC treatment, catalytic oxidizers come with lower operating cost and better fuel efficiency. Since catalytic oxidizers of good brands offer superior heat recovery, they are able to bring down the manufacturers’ energy costs, adding to their advantages.

Differences between VOC thermal oxidizer and Catalytic Oxidizers
 
Apart from the energy consumption differences between the two types of Oxidizers, following are some other noted differences between the two.

Attributes of Catalytic Oxidizers
•    These are primarily used when the flow of exhaust is somewhat slow, but the VOC concentration is high.
•    These oxidizers are used with lower temperature air streams.
•    Here, VOCs are destroyed by using metal catalyst monoliths.
•    Though these equipment demand bigger initial investment due to the customized features of catalytic bed, these oxidizers are typically known to offer longer life.

Attributes of Thermal Oxidizers
•    These oxidizers have significant uses in industries that have larger volumes of low VOC concentrated exhausts.
•    These are used for higher activity periods in higher temperatures.
•    Since catalyst beds are respond sensitively to certain emissions, these are used more in industries.
•    Come with smaller initial investment.

Keeping all these differences in mind, you can choose the oxidizers that fit your needs and give better advantages over others. Give your employees a save working environment by using VOC concentrations system and make the most of your industrial investments.

How Is Recuperative Thermal Oxidizer A Must Have Device For Industrial Processes?

Recuperative thermal oxidizers are essential for your workplace to have an effective control over different processes and provide greater efficiency. The function of industrial device called thermal recuperative oxidizer is to treat the exhaust air produced by industrial equipment. The device uses ceramic material for absorbing heat that industrial equipment generate and spread in the surrounding environment. Thermal oxidizer not only keeps the heat from coming out, but its absorbed heat is used again for preheating the incoming process gas; which is a great way to save a lot of energy at a heavy duty factory.

Make the environment safe using recuperative oxidizer

 
If you’re not acquainted with the working processes of large industries, the use of device may sound strange to you, but industrial thermal oxidizer is highly useful in these industries, especially when the heavy duty appliances are used round the clock. Since overheating due to the machines is hazardous and can result in unavoidable accidents, recuperative thermal oxidizers offer great help. With the capability of these devices to control the damaging particles from entering the workplace, you can avoid the threat posed to your health in the long run. Using these devices, companies not only can save the lives of their employees, but also cut down on the huge overall cost of operation.

Choose the right model

 
Due to the rising demand in the market, a variety of models have been designed of industrial thermal oxidizer for specific appliances. With help of a machine expert, you can purchase a recuperative catalytic oxidizer that fits the custom requirements for your appliances. However, before purchasing a particular model, find out about its specifications and offered benefits to prevent the environment from heating in a smart manner. Using a suitable model of industrial thermal oxidizer, you will not just be able to keep the environment pollution-free, but also bring down the maintenance cost of the device.

How Industrial Thermal Oxidizer Helps in Pollution Control?

Thermal oxidizer is one of the essential components of air pollution control mechanisms used by chemical plants across the world. Air pollution control systems having thermal oxidizers are used across industries.The primary job of this device is to eliminate hazardous gases and gaseous chemicals from the process stream of a plant.

The decomposes gases under a very high temperature and pressure, before releasing them freely into the atmosphere.The use of industrial thermal oxidizer helps the processing unit to ensure that they are releasing no harmful gases in the environment and keeping up with the government norms.

There are different types of oxidizers, such as catalytic oxidizers, that follow completely different process to destroy air pollutants.To be specific, catalytic oxidizers use catalyst to carry out the oxidation procedure.

This is how thermal oxidizer helps eliminate air pollutants –

• There is a robust, high-pressure air fan that pushes exhaust stream (airflow packed with gaseous and chemical elements) into the thermal oxidizer.
• Technically, this gas flow is sent into an energy recovery canister.
• From there, the flow is directed into a heat exchanger unit, where a strategically placed ceramic medium absorbs heat being carried by the airflow.
• Then, the air is sent into a combustion chamber, which has a very high temperature – which is required for accomplishing the oxidation process.
• It is the combustion process, where the pollutants and gaseous elements are removed from the airflow, before it is released into the atmosphere.

By ensuring that you are using a good-quality thermal oxidizer at your plant, you can limit the release of pollutants in environment, thereby, contribute in making a cleaner and safer to live environment.

Thermal Recuperative Oxidizers: Best Method to Combat with Pollution

To serve the growing needs of the population, different types of industries are setup to produce a variety of different products.While manufacturing the products, waste is generated during washing and processing of raw materials. The waste is liberated from a variety of organic and inorganic raw materials which are then released in the form of fly or ashes. The waste is toxic in nature that can be harmful to living organisms and environment. Thus, this is an introduction to pollution, bad contaminants in the natural environment. The best method to combat with the pollution is by controlling it and this can be done with the help of recuperative oxidizers. 

Benefit of using thermal recuperative oxidizers:

•    Trouble free operation

•    Highly effective

•    High thermal efficiency

•    Quick start-up

•    Large turn-down ratio

•    High destruction efficiency

•    Low operating costs

Recuperative thermal oxidizers are used for controlling environmental pollution by decomposing hazardous gases at a high temperature thereby releasing them into the atmosphere. Thermal recuperative oxidizer(TRO) has a two layered heat exchanger within the system, one is primary and other is secondary.The primary heat exchanger preheats the dirty air by recuperating heat from the exiting clean air. This process is performed by a shell and tube heat exchanger or a plate-type exchanger. The same concept is used in secondary layer of heat exchanger but the heated air is either transferred to the other parts of the plant or perhaps back to the process.

Today industries have been increasingly using this catalytic oxidizers that helps in solving environmental and global warming issues. This machinery helps in meeting most stringent air pollution abatement regulations.

Thermal oxidizers: which one is better?

With the advent of stricter environmental restrictions, a clean air solution that has emerged as the most sought after or written about is recuperative thermal oxidizers as well as regenerative.
However, do we really know how they are different from each other?

Let us chart the difference between these two oxidizers and their respective advantages.

Design

Recuperative oxidizer, as the name implies, recovers heat from the combustion of the hazardous gases. The primary thermal oxidizers did not have recovery stage and what all they did was decomposing half-burnt gases by exposing them to the high temperatures. However, designers came with modern oxidizers that make use of the heat produced by the combustion of gases for other purposes in a plant as well efficiently use the heat for decomposition of gases. Recuperative design has a couple of heat exchangers in the form of pipes and shells, which recovers the excessive energy and sends it to the plant.

Whereas the regenerative design has a ceramic bed that acts as a heat exchanger, the design makes it more efficient at recovering heat, and that is why it is named regenerative. The exhaust gases are pre heated as they move over the heated ceramic bed, and is partially oxidized, and then it enters the center of the unit, which has combustion center. In the chamber, a fuel is used to increase the temperature further high, so the gases are combusted completely.

Advantages of recuperative oxidizer

•    This design needs lower amount of fuel for combustion
•    The system has catalyst that destroys carbon monoxide in the waste stream
•    It has lower oxides of nitrogen emissions than regenerative

Advantages of RTO

•    Lower fuel requirement than traditional oxidizer, however, larger than recuperative design
•    Not much susceptible to chlorinated compounds
•    High-temperature efficiency

Both of these designs, evidently, have their own sets of advantages; therefore, choosing which design will work better under certain conditions require further analysis. Meet a supplier to understand to know details.
