Reusing of Carbon Dioxide in Steel Plants

It is reported that one steel plant in the UAE is taking part in an innovative and ambitious project whose aim is to capture, reuse and store 800,000 tonnes of carbon dioxide (CO₂) from its steel plant annually. The project is scheduled to be completed by 2016. The goal is to produce steel with lower carbon dioxide emissions to the atmosphere by capturing the CO₂ produced in the iron and steel making process, injecting it into existing oil fields for enhanced oil recovery (EOR) and storing it at the same time.

Generally speaking, the CO₂ supply stream from a steel plant contains approximately 90% CO₂, the CO₂ can be directly compressed and dehydrated or transported to a compression and dehydration facility at a storage site. The CO₂ can be compressed creating CO₂ with a purity of 98%, and then be transported through a long enough pipeline network, and finally injected into an oil field.
