Pipeline for underground carbon dioxide storage  


Posting by holger on July 04, 2008 at 22:00:09.

I was wondering whether one should use
- glass fibre reinforced epoxy / unsaturated polyester or
- coated / stainless steel
for carbon dioxide (co2) pipeline applications.

What are the advantages / disadvantages of both materials particularly for CO2 pipeline and additionals like pumps and field joints. Low weight is not a major issue, I am mainly interested in carbon dioxide, water, carbonic acid chemical or corrosion kinetics and subsequent or simultaneous chemicals permeation rates.

Secondly, is there any insight in the formation of CO2 hydrates, due to presence of water /moisture, and subsequent chemical and diffusion, permeation impact on unsatureated polyester frp or stainless steel pipes fpr CO2? I would like to learn more on hydrate formation and the use of Methanol in these circumstances.

Danke,
Holger

    Hello Holger,

    In in the United States there are a few big CO2 pipelines at this moment. The material that they use for the pipeline is carbon steel (X60)

    I dont't have any info on corrosion etc. at this moment present but there are many scientific articles writen about this subject.

    A big US company that build/own CO2 pipelines is "Kinder Morgan"

    You could try to contact them.

    (my excuses for my english i need to refresh it)

    Greetings Hendrik

      Many thanks Hendrik for your interesting reference! Indeed X-60 is the preferable material for transport of gases like Hydrogen. With regard to CO2, especially if some water is present, I would really think that polymers or plastic based composites have the potential to show a better overall technical and economic performance.

      Thanks again,
      Holger

    Hi, forgot to ask whether an internal PPS - CO2 liner in an existing steel pipeline is also an option? What sort of liner / lining matetial do you recommend for CO2 at 100 bar?
