Krantz Clean Air Solutions - We combine climate protection and energy generation
Our ambition: Converting solvent emissions to heat and power.
For more than 30 years we have been combining the energy requirements of a production with the legal requirements to clean solvent-containing exhaust air by a holistic approach. Our continuous developments make it possible to transfer the energy contained in the solvents to heat transfer media for use in production - often without the additional use of fossil fuels such as natural gas or oil.
For example, we generate high-quality saturated steam from the solvents emitted during the manufacture of adhesive tapes. The steam generated is then used to heat the coating equipment. In this way, 600 kg of solvent is turned into 4.5 t of saturated steam at 220 °C per hour.
In these plants, the solvents are collected with the exhaust air from the coil coating lines and purified by oxidation in a regenerative afterburning system. Although the required oxidation temperature is 850 °C, no natural gas is needed to reach it. There is enough energy in the solvents. And not only that. The available excess heat can be discharged from the combustion chamber and used to generate steam.
In another exemplary example in the paint industry, micro gas turbines have been used to generate electricity and heat from solvents since 2020. How we succeed in this, you can see in this article:
Fit for the future
We are currently working intensively on the complete substitution of fossil fuels with electricity and hydrogen. Several reference projects have already been successfully realized. In 2022, for example, we succeeded in operating an existing thermal exhaust air purification plant with low solvent concentration in a CO2-neutral manner by using hydrogen.
