RTO Thermal Oxidizer Sizing

Introdução

RTO thermal oxidizers are widely used to treat air pollutants emitted from chemical, petrochemical, and pharmaceutical processes. The sizing of Oxidador térmico RTO
s is a crucial step in their design and operation. In this article, we will discuss various aspects of RTO thermal oxidizer sizing.

Factors Affecting RTO Thermal Oxidizer Sizing

The following factors play a significant role in determining the size of RTO thermal oxidizers:

Process Flowrate

The process flowrate is the most important factor in RTO thermal oxidizer sizing. It determines the size of the oxidizer’s combustion chamber and heat exchanger. The higher the flowrate, the larger the RTO thermal oxidizer required.

Concentration of Pollutants

The concentration of pollutants in the process stream also affects the RTO thermal oxidizer sizing. Higher pollutant concentrations require larger RTO thermal oxidizers to ensure efficient treatment.

Pollutant Composition

The composition of pollutants in the process stream can affect the RTO thermal oxidizer sizing. For example, if the process stream contains halogens or other compounds that can corrode the oxidizer’s materials, a larger RTO thermal oxidizer may be required.

Process Temperature

The process temperature can also affect the RTO thermal oxidizer sizing. Higher process temperatures can result in higher thermal energy recovered by the heat exchanger, which can reduce the size of the RTO thermal oxidizer required.

RTO Thermal Oxidizer Sizing Calculation

The following steps are involved in RTO thermal oxidizer sizing:

Step 1: Determine Process Flowrate

The process flowrate is determined based on the mass flowrate of the process stream and the concentration of pollutants.

Step 2: Calculate Heat Load

The heat load is calculated based on the process flowrate, the concentration of pollutants, and the process temperature.

Step 3: Calculate RTO Thermal Oxidizer Size

The RTO thermal oxidizer size is calculated based on the heat load, the residence time, and the destruction efficiency required.

RTO Thermal Oxidizer Sizing Example

Let’s consider the following example to illustrate RTO thermal oxidizer sizing:

Process Flowrate: 1000 kg/hr
Concentration of Pollutants: 500 ppm
Pollutant Composition: 50% VOCs, 50% HAPs
Process Temperature: 150¡ãC

Step 1: Determine Process Flowrate

The process flowrate is 1000 kg/hr.

Step 2: Calculate Heat Load

The heat load is calculated as follows:

Heat Load = Process Flowrate x Pollutant Concentration x Heat of Combustion

The heat of combustion is calculated based on the pollutant composition. In this case, it is assumed to be 30,000 kJ/kg.

Heat Load = 1000 x 500 x 30,000 / 1,000,000 = 15,000 kW

Step 3: Calculate RTO Thermal Oxidizer Size

The RTO thermal oxidizer size is calculated based on the heat load, the residence time, and the destruction efficiency required. Let’s assume a residence time of 0.5 seconds and a destruction efficiency of 99%.

RTO Thermal Oxidizer Size = Heat Load / (Residence Time x Destruction Efficiency)

RTO Thermal Oxidizer Size = 15,000 / (0.5 x 0.99) = 30,303 Nm3/hr

Based on this calculation, an RTO thermal oxidizer with a capacity of 30,303 Nm3/hr would be required for this process.

In this article, we discussed various aspects of RTO thermal oxidizer sizing. The sizing of RTO thermal oxidizers is a crucial step in their design and operation. Proper sizing can ensure efficient treatment of air pollutants and reduce operating costs.
