A CO2 closed-loop transport test rig has been designed, constructed and operated by CIUDEN. Its design covers a wide range of operating conditions compatible with the recommended general guidelines for CO2 transport. The transport rig aims to cover the aspects considered of interest in the field of CO2 transport being a facility close to a real CO2 transport infrastructure. The facility also aims to be a reference at global level for terrestrial transport of CO2 though pipelines. CIUDEN´s CO2 Transport Test Rig has a semi-industrial size. In order to operate the test rig in thermal conditions similar to those expected in CO2 transport pipelines (mainly buried), the facility is located inside a thermal isolated building with temperature control. The building maintains the temperature constant for the experimentation, preventing the effects of ambient temperature and thus approaching the isothermal transport conditions that are typical of the buried sections of a pipeline. The building is made with concrete-isolation sandwich material with an effective ventilation system to avoid sub-oxygenated atmospheres. The CO2 Transport Test Rig includes the following main units:

  1. Pumping system to fill the closed loop rig with CO2 either from a storage tank of the Centre (commercial quality) or from the CPU tank (Compression and Purification Unit) (real captured CO2)
  2. High pressure vessel to avoid fluctuations in the flow
  3. Recirculation pump and heat exchanger system to set operation pressures and temperatures.
  4. Dosing area to add impurities and contaminants to simulate different CO2 streams compositions expected for transport. Any tailor-made stream with substances such as H2O, NOx, SOx, N2, O2, Ar, CO, H2, H2S and CH4 could be achieved. It is important to point out that in addition to the oxy-combustion technology, the Transport rig is designed to test CO2 streams including typical contaminants from other CCS options such as pre- and post-combustion technologies.
  5. Tube coils: each coil has an equivalent length of approximately 300 m and a 2” nominal diameter. Considering the number of tube coils (10), the length of the whole test rig is around 3,000 meters. It is possible to by-pass any of the coils in order to adapt to specific tests and lengths.
  6. Test areas in order to carry out different experiments, such as: equipment or instrumentation testing, elastomers behaviour, sudden depressurizations, controlled pressure losses, corrosion and material testing

CIUDEN´s CO2 Transport Test Rig will provide valuable data as a basis for the design, maintenance and operation of industrial CO2 pipelines. The results obtained will help to design a safe scale-up of the CO2 transport technology. The rig is highly monitored. In the Control System, around 150 variables are gathered. These signals mainly comprise temperature, flow-rate and pressure measurements as well as fluid properties such as density and viscosity. Several continuous online analysers have been set in order to control the composition of the CO2 stream within the installation.

State of the art, uniqueness, & specific advantages

The CIUDEN Transport Test Rig will allow testing the effects on pipeline performance of the following parameters: CO2 composition, materials behaviour and process performance (corrosion, pressure and temperature changes, pressure drops in pipelines and accessories, etc). The uniqueness of the installation is its size and the ability to make dynamic tests on certain CO2 flow in conditions similar to those of a real pipe that would allow the scale up of the results. Current performed and committed tests include depressurization and impure CO2 streams.

Scientific Environment

Further services at the same location are offered: fully equipped laboratories and specialized operating staff. Offices and laboratories (3,500m2 ) and contractors offices and workshop (1,300m2 ), Personal Protective Equipment, Warehousing for tested equipment and Maintenance Shops (mechanical, electrical and Inspection and Control), IT support, offices and testing space. Equipment and instrumentation behaviour, depressurization, flow assurance, material testing and any other safety CO2 transport operations can be arranged.
