Mannesmann CO2ready®

Safe and reliable

According to the International Energie Agency (IEA), the transport and storage of CO2, as things look today, will play an important part in achieving the ambitious climate protection target of an 80-95% reduction in carbon dioxide emissions in the industrialized nations by 2050.

HFI-welded steel pipes from Mannesmann Line Pipe are the ideal choice for the transport and storage of large quantities of CO2. The outstanding quality of our pipes ensures a high level of safety and reliability and thus offers optimum protection, both for the population and for the environment.

In a series of successful tests conducted together with a consortium of network operators, gas and energy suppliers, pipe manufacturers and research institutes, our Mannesmann CO2ready® steel pipes performed impressively across the board. We would be happy to submit you an offer tailored to your project.

Generation, storage and utilization of CO2

Carbon dioxide (CO2) is a compound consisting of carbon and oxygen. The gas is released in large quantities, among other things, through the combustion of fossil fuels, such as crude oil, natural gas and coal. In other words, fuels that are used, for example, in industry to generate energy and for road transport. However, it is not CO2 per se that is harmful, but the share of the gas in the earth's atmosphere.

You can find further information on this here:  Kohlendioxid: Wie entsteht CO2 und was bewirkt das Klimagas? (meravando.de) or Wie entsteht CO2? Verständlich erklärt (focus.de).

Very large quantities of CO2 are currently released, particularly in such industrial processes as the production of cement involving the combustion of fossil fuels. However, suitable capture processes can largely prevent this. These include, for example, the long-term storage of the gas (CCS = Carbon Capture and Storage) and its reuse (CCU = Carbon Capture and Utilization).

You can find further information on this in our datasheet on this page.

Mannesmann CO2ready® pipes under scrutiny

Very rarely is it possible to store or reuse CO2 where it is produced. For transporting what are sometimes large quantities in an economically viable way, pipelines are the right choice. Our Mannesmann CO2ready® steel pipes are a safe and reliable product from one of the world's leading specialists in the manufacture of longitudinally HFI-welded steel pipes. We were able to demonstrate this in the SARCO2 project (Requirements for safe and reliable CO2 transportation pipeline) sponsored by the European Commission – Research Fund for Coal and Steel. In this project, Mannesmann Line Pipe GmbH teamed up with the renowned research institutes Salzgitter Mannesmann Forschung GmbH (Germany) and Centro Sviluppo Materiali S.p.A. (Italy, now RINA S.p.A.) to successfully test longitudinally HFI-welded steel pipes.

Corrosion tests investigated how impurities in the gas (e.g. hydrogen sulfide (H2S), hydrogen (H2), nitrogen dioxide (NO2), sulfur dioxide (SO2) and nitrogen (N2)) and the parameters during transport of CO2 mixtures affected the general and local corrosion behavior. Our pipes performed impressively across the board, provided that there was no excess water in the gas due to improper operating conditions.

Mechanical/technological investigations and full-scale burst tests on a 220 m long test pipeline also demonstrated that, despite CO2's "supercritical" state during cost-effective pipeline transport (two-phase mixture: liquid and gas), the pipes exhibit outstanding toughness and crack arrest behavior. Here, too, our pipes proved to be absolutely dependable.

Conclusion

Mannesmann CO2ready® pipes from Mannesmann Line Pipe are ideal for the transport and storage of large quantities of CO2. This makes our pipes FIT FOR THE FUTURE.

Carbon dioxide (CO2)

What you always wanted to know.

CO2 generation

CO2 is mainly generated as a by-product of cellular respiration in many living organisms or during the complete combustion of material consisting predominantly or entirely of carbon. Carbon dioxide plays a prominent role in the photosynthesis of plants, since plants with the aid of solar energy and water can convert CO2 first into fructose and then into glucose (= sugar/energy) in several steps.

Further information www.klima-wandel.eu

 

Industrial production of CO2

Alongside transport and households, the largest amount of CO2 is released in industrial processes. CO2 is produced, for example, by the combustion of such fossil fuels as oil, gas or coal. The carbon emissions per burned metric ton of OE* are 2.28 t for lignite, 1.88 t for hard coal, 1.61 t for crude oil and 1.05 t for natural gas.

Further information www.bund-nrw.de

*) 1 kg of OE is equivalent to the quantity of energy generated by burning 1 kg of crude oil.

The production of cement causes high greenhouse gas emissions (GHG). This is firstly is caused by the large amount of fuel consumed in the combustion process at the high temperature required (around 1450 °C), in which the limestone feedstock is fired to produce (cement) clinker. And, secondly, the chemical reaction during the calcination of the limestone results in the release of CO2. Further emissions are caused by electricity consumption during grinding and the transport of raw materials and end products. In total, this results in an average greenhouse gas potential of 587 kg CO2 equivalent per ton of cement in Germany (see also VDZ / IBU (2017): Environmental Product Declaration (EPD), average for cement in Germany

Carbon capture technologies

When fossil resources are burned, the first step is the capture of the generated carbon. At power plants, there are various ways to reduce the release of CO2 into the atmosphere. Using three main capture processes, it is possible to achieve CO2 reductions of 80 to 98 percent in the exhaust gases of power plants. Current research and development work is aimed at increasing the efficiency of the processes and developing second-generation capture processes (membrane processes and carbonate looping, for example).

Pre-combustion process

Solid fuels, e.g. hard coal or lignite, can be gasified. The carbon dioxide can be separated in the course of the gasification process. During the process, the coal is not burnt as in a conventional steam generator, but is first converted into a fuel gas in a gasifier. The pressurized gas is then cleaned and the CO2 is removed. What remains is almost exclusively hydrogen. This is then burned in a gas turbine.

 

Oxyfuel process

In this process, fossil fuels are burned with pure oxygen and the resulting CO2 is then captured.

 

Post-combustion process

Here, it is possible to capture carbon after the conventional combustion process. This process makes use of downstream flue gas scrubbing, in which amines or amino acid salts, for example, are used as scrubbing agents or solvents.

Carbon Capture and Storage (CCS)

This involves the capture of carbon dioxide at power stations or industrial facilities and subsequent storage in geological strata at depths of around 1000 to 4000 meters. Suitable storage rocks include, for example, former oil or gas reservoirs and saline-water-bearing rock strata. Numerous countries, such as the USA, Canada, Australia, Algeria and Norway, already have several years of experience with carbon storage. In the case of oil and gas reservoirs, the carbon dioxide can be used to recover the crude oil or natural gas that could not previously be extracted from the reservoirs (known as enhanced oil or gas recovery). In addition, CCS could also be applied in CO2-intensive industries, such as cement, steel and aluminum production and the petrochemical industry. On the basis of current knowledge, CCS technologies are the only way in the foreseeable future to significantly reduce the approximately 80 million tons of CO2 produced annually by these industrial processes in Germany.

Carbon Capture and Utilization (CCU)

In addition to its use in oil and gas production, CO2 is now also used in material applications, amounting worldwide to about 110 million tons as feedstock (including urea, cyclic carbonates, salicylic acid) and about 20 million tons as an industrial gas. In addition, there are many innovative ideas and approaches on how CO2 could be used as a carbon source in the future, including for polymers and insulation materials, fine chemicals, in methanol production, photocatalytic activation, utilization by microalgae and re-methanization with hydrogen. However, given the limited medium-term volume potential known today, CO2 utilization seems likely to be only a complement to CO2 storage.
