Process equipment and heat recovery systems

Smoke tube boiler design with intelligent connection to a combustion chamber and custom-designed internal or external bypasses.

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.

Equipment for synthesis gas cooling after steam reformers.

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.

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.

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.

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.

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.
