  • quality 5.0 /> 99.999 % guaranteed with fluctuating volume flows of 10 % – 100 %
  • operation also possible at less than 10 % utilization
  • use in pressure ranges from atm. to 400 bar ü
  • low space requirement due to low impact on the dimensions of the frame
  • no additional maintenance costs
  • start/stop operation possible

Power-to-X plants (PtX) for the production of green hydrogen are powered by renewable electricity, e.g., from photovoltaics and wind power. As the supply of electricity from wind or solar power is unstable, PtX plants must be designed to operate with fluctuating volume flows. However, gas purification systems have mainly been used in industrial settings, where constant volume flows are used. Therefore, the application in PtX systems poses a new challenge for gas purification systems: achieving high gas purities even with fluctuating flow rates.

With our extensive experience in gas treatment, we have developed the ReiCat HighFlex H₂® Technology. This reliable process ensures a consistent hydrogen quality of 5.0 or a purity of > 99.999 %, even when the hydrogen purification system is operated with fluctuating flow rates between 10 % – 100 %. This reliability makes our technology a dependable choice for PtX systems.

Frequently
asked questions

What is Power-to-X and what role does gas purification play?

Power-to-X (PtX) refers to processes that convert renewable electricity into other forms of energy. A typical application of PtX is the production of green hydrogen by electrolyzing water with electricity from photovoltaics and wind power. Green hydrogen leaves the electrolyzer with impurities, mainly oxygen and moisture. However, a gas of high purity (> 99.999 % or quality 5.0) is required for transportation, storage, and most applications. Therefore, ReiCat gas purification systems are essential to every PtX system.

Does ReiCat HighFlex H2® Technology also work with volume flows < 10 %?

Yes. Under certain conditions, ReiCat HighFlex H2® Technology can guarantee consistent purification performance with volume flow fluctuations of 5 % to 100 %.

What are the advantages of ReiCat HighFlex H2® Technology?

ReiCat HighFlex H2® Technology guarantees a consistently high hydrogen quality 5.0 even with fluctuating volume flows between 10 % – 100 %. In some instances, volume flows < 10 % are possible. Commercially available gas purification systems without HighFlex H2® Technology are not designed for strong fluctuations in the volume flow and, therefore, cannot guarantee consistent purification performance.

Can ReiCat HighFlex technology also be used to purify oxygen in PtX applications?

Yes. Water electrolysis produces not only hydrogen but also oxygen. This green oxygen leaves the electrolyzer with impurities, mainly residual hydrogen and moisture. If the oxygen is to be used further, for example, in medicine, it must first be purified. The ReiCat HighFlex Technology, initially developed for hydrogen purification systems, can also be used in the corresponding ReiCat oxygen purification systems for PtX applications.
