Austria: Rohdorfer Zement has increased the capacity of the pilot CO₂ capture facility at its Rohrdorf cement plant to 99%. The facility can now capture 2t/day of CO₂, up from 0.9t previously. This is due to a second absorption column, which was installed in March 2026, directly behind the first. The facility also employs an oxystripper from Andritz, which has been use since July 2026. The oxystripper removes approximately 90% of the oxygen dissolved in the amine scrubbing solution to increase both the purity of the captured CO2 and the lifespan of the scrubbing solution.
“Since the capture plant went online, we have been working consistently to further increase the plant’s performance and energy efficiency. With the second column and the oxystripper, we have reached an important milestone in this effort. At the same time, these measures have enabled us to further improve CO2 quality in a targeted manner and to come significantly closer to meeting the very challenging requirements for storage,” said Christian Räthel, Head of CCUS for Rohrdorfer’s Net Zero Emissions Team.
