Process equipment and heat recovery systems
Increase performance and efficiency of your production plant through energy recovery
Create synergies in your production process with process equipment and process heat recovery systems and increase the efficiency of your system. With our modular solutions for heat recovery, you can use the energy generated in your production process elsewhere, e.g., to generate (hot) steam or heat up process gases, feed water and combustion air. This allows you to cut energy costs and reduce emissions. We support you with our expertise to jointly develop the right energy recovery solution for your requirements and to help you make optimum use of it in your production process.

Areas of application for process equipment and heat recovery solutions
Process equipment from Dieffenbacher Energy
High temperature boilers
High temperature boilers
Smoke tube boiler design with intelligent connection to a combustion chamber and custom-designed internal or external bypasses.
High pressure U-tube heat exchangers
High pressure U-tube heat exchangers
Pressures of over 300 bar on the gas side and over 120 bar on the water side result in FEM-calculated forged chambers and tube plate details for these heat exchangers.
PGBs, PGCs, WHBs & steam drums
PGBs, PGCs, WHBs & steam drums
Equipment for synthesis gas cooling after steam reformers.
Formaldehyde Converter
& steam drums
Formaldehyde Converter
The silver catalyst process is used to turn methanol into formaldehyde. A stainless steel pressure vessel with a detailed design serves as a converter/reactor.
Heat recovery systems from Dieffenbacher Energy
Heat recovery systems
following steam methane reformers (SMRs)
Heat recovery systems
Most of the waste heat from the reformer is used to produce steam and superheat it to heat gas mixtures, air and condensate. These media are fed back into the steam reforming process, completing the cycle.
Economiser & superheater modules
following sulfur trioxide converters
Economiser & superheater modules
In sulfuric acid production, the heat of the process gas from various stages of the contact furnace (racks) is used to heat water or superheat steam. As the process gas is under pressure, the housings of the required heat exchangers are often cylindrical in shape.
Revamp modules
and express coils for WHRS
Revamp modules
At the end of the service life or when improvements are planned, sometimes only individual modules of a heat recovery system are replaced. Accuracy of fit, compliance with the latest regulations, the desired improvements and short delivery times are the keys to success.
Heat recovery boilers
in combustion plants
Heat recovery boilers
The combustion of waste gases or residual liquids in the chemical industry occurs at high temperatures in strictly monitored processes. The requirements for waste heat boiler quality are particularly high and can only be met by considering all worst-case scenarios during design.
