Enhanced Oil Recovery (EOR)

In 2008, Linde secured a strategic contract in the United Arab Emirates in the Middle East.

Through this joint venture with the Abu Dhabi National Oil Company (ADNOC), Elixier, Linde is set to construct two large air separation plants in Abu Dhabi, the country’s capital. The project will involve a total investment volume of around USD 800 million. The new plants will have a total capacity of 670,000 scm/h of nitrogen.

The nitrogen will be used to extract natural gas. It will be injected into the on-shore condensate fields at Habshan. The gas is to be transported 50 kilometres inland by pipeline from the coast to the Habshan field at a pressure of 60 bars.

Here it will be injected into ADNOC gas reservoirs to create a constant pressure level, enabling the gas to be pumped to the surface more evenly to secure future supplies. It also means that the natural gas ADNOC is currently using for this purpose can be used to generate power.

This is a welcome change for a fast-growing region where energy consumption is constantly rising.

The two air separators located at the Mirfa complex are based on the Cantarell/Mexico air separator blueprints. Using these blueprints has the added advantage of a short time-to-delivery coupled with the proven safety of these successful installations in Cantarell.
