How to size an RTO with heat recovery system?

1. Understanding the Basics of RTOs

Regenerative Thermal Oxidizers (RTOs) are air pollution control systems used in industrial processes to remove volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from exhaust gases. These systems utilize high temperatures to convert pollutants into harmless byproducts. Sizing an RTO with a heat recovery system is crucial for optimizing its performance and energy efficiency.

2. Determining the Process Flowrate

The first step in sizing an RTO with a heat recovery system is to accurately determine the process flowrate of the exhaust gases. This can be done by measuring the volumetric flowrate or using mass flow meters. The flowrate data is essential for selecting the appropriate RTO size to handle the exhaust gas volume.

3. Calculating the Heat Load

Once the process flowrate is determined, the next step is to calculate the heat load of the exhaust gases. The heat load is the amount of energy that needs to be removed by the RTO with heat recovery system. It is calculated by multiplying the flowrate with the specific heat capacity of the exhaust gases and the temperature difference between the inlet and outlet.

4. Selecting the RTO Size

Based on the calculated heat load, the RTO size can be selected. It is important to choose an RTO that can handle the heat load while maintaining optimal operating conditions. Factors such as residence time, heat exchange efficiency, and temperature control should be considered during the selection process.

5. Evaluating the Heat Recovery System

The heat recovery system in an RTO plays a vital role in improving energy efficiency. It recovers and transfers heat from the hot exhaust gases to the incoming process air or other heat sinks. The sizing of the heat recovery system depends on the heat load, operating temperature, and desired energy recovery efficiency.

6. Optimizing the RTO Performance

To optimize the performance of the RTO with heat recovery system, proper control strategies and monitoring systems should be implemented. This includes maintaining the desired temperature profile, monitoring pressure drops, and ensuring effective heat transfer within the system.

7. Implementing Safety Measures

When sizing an RTO with a heat recovery system, it is essential to consider safety measures. This includes incorporating safety devices such as flame arrestors, explosion venting, and temperature sensors to prevent any potential hazards.

8. Regular Maintenance and Monitoring

Once the RTO with heat recovery system is operational, regular maintenance and monitoring are crucial. This includes inspecting and cleaning heat exchangers, checking for air leaks, calibrating temperature and pressure sensors, and ensuring proper functioning of control systems.
