Regnerative Thermal Oxidizer
The main argument for selecting the regenerative over the recuperative technology is the outstanding heat recovery efficiency which is achieved thanks to the extraordinary surface area of the heat storage media. It can be assumed that regenerative systems easily reach a thermal efficiency of 95% or even higher. This means that heat recovery is nearly twice as high as it would be when a recuperative tube-shell heat exchanger is used. Apart from the significant savings in support fuels for operation, the system shows a relatively low pressure drop resulting in reasonable overall OPEX figures. Shut-down inspections are usually required once per year. There are some specific petrochemical applications, however, for which uninterrupted operation for up to 4 years has been achieved. The robust and proven design by DUMAG ensures trouble-free operation and long service life – even under harsh conditions.
The RTO treatment technology has been implemented for a wide range of industrial applications in the past decades. The equipment treats emissions from various production or handling processes reliably for years, including chemical and pharmaceutical production plants, refineries or tank terminals.
The destruction of odorous, harmful, toxic or carcinogenic organic substances takes place in the combustion chamber at temperatures from around 800 up to 1100 °C. As a result of the high temperature treatment, organic compounds are converted into harmless products of combustion, such as H2O and CO2. On the right you can see a selection of substances that have been treated successfully with the RTO technology.
Ceramic honeycombs have proven their value as the most efficient heat storage media for regenerative use. Blockages are very unlikely thanks to the straight channel structure. Depending on the material and number of cells (cpsi), the particle tolerance, the heat and chemical resistance as well as the heat storage capacity can all be selected specifically for each application.
Customers benefit from DUMAG’s broad combustion expertise and will obtain the perfect burner design for economic and effective operation of the RTO system. The implementation of a DUMAG multi-fuel burner (MFB), for example, offers the possibility of changing between two different fuel sources – gas or liquid – for maximum flexibility in operation. Furthermore, DUMAG develops customized solutions for complex treatment tasks, such as the integration of injection devices for safe introduction of concentrated process vent gases from reactors directly into the RTO combustion chamber.
A mobile controls solution allows the operator, after a security check, to query the operating conditions directly on the system and to change settings if necessary. The user interface is intuitive and has various rights levels. The times of an HMI on the control cabinet and tedious communication via radio are history.
