Innovative ideas for pioneering CO₂ applications
KSB looks back on 150 years of technological innovation – and uses this passion to take the necessary steps towards a sustainable future. One of the key issues we face is how to deal with CO₂. Capturing, transporting, using and storing carbon dioxide are important fields in which KSB is developing vital technologies and setting trends.
We are driving forward the development of CCUS (carbon capture, utilisation and storage)

CO₂ can be captured using a variety of methods, each with its own specific challenges. KSB offers solutions for all capture technologies (chemical and physical absorption, direct air separation, etc.) at all separation stages (pre-combustion, post-combustion and oxyfuel):
- Lean amine solution for CO₂ absorption
- Transfer of liquefied CO₂
- Desulphurisation fluids for purification
- Process water for the synthesis gas scrubber
- Process condensate for the stripper flow and coolant injection
- Demand-driven cooling, scrubber and boiler feed water supply in the overall system
After it has been captured, the CO₂ can be compressed to form a fluid that is almost as dense as water. When the CO₂ condenses below its critical point, it can be pumped and transported by pipeline, truck or ship. HG(opens in a new tab) and CHTR pumps are the perfrect choice for the main process. Butterfly valves from the DANAÏS CRYO and TRIODIS series are ideal for the particularly demanding process of liquefaction.
Carbon storage involves the permanent storage of CO₂ in underground geological formations. With geological storage, CO₂ captured during industrial processes is injected into rock formations deep underground, permanently removing it from the atmosphere:
- in saline formations
- EOR (enhanced oil recovery)
- in depleted reservoirs
In a combustion chamber, natural gas is mixed under high pressure with oxygen and supercritical CO₂ from the capturing process and burned. The resulting very hot working fluid expands in a turbine before being cooled in a heat exchanger. The water that forms condenses and is then separated, leaving a gaseous CO2 flow. The excess CO₂ is fed into a pipeline so it can be used elsewhere or stored underground. The remaining CO₂ flow is compressed, cooled and pumped under high pressure using pumps from KSB. In the heat exchanger, the CO₂ flow is heated up again and then returned to the combustion chamber.
Once the CO2 has been captured, it can be used as a raw material to manufacture products or provide services, for example climate-neutral energies such as synthetic and biofuels, chemicals, plastics, fibres and synthetic rubber. KSB offers a wide range of pumps and valves for such purposes.
