In Salah Project

One of the Largest CCS Facilities

In 2004, Sonatrach and BP/Statoil began separating CO₂ from natural gas at the In Salah gas facility in Algeria. The CO₂ is being re-injected into a sandstone reservoir for permanent storage. KBR provided the Engineering, Procurement, and Construction for this carbon sequestration project which is one of the three largest CCS facilities in the world.

In the In Salah project, the natural gas has a high level of CO₂ which is captured using activated MDEA. The CO₂ free gas is dehydrated and compressed for distribution as sales gas.

For the In Salah project, about 1 million tons per year of CO₂ is compressed in two trains, dehydrated using triethylene glycol after three stages of compression, and undergoes final compression before it enters the CO₂ pipeline.

These pipelines transport the CO₂ to reservoirs which are up to 20 km away. Finally the CO₂ is injected into the reservoirs at depths of 1.8 to 2 km below the surface.

KBR has the experience and the lessons learned here to successfully execute future large-scale CCS and geological sequestration projects.
