The Shah plant — built and operated by a joint venture between ADNOC and Occidental Petroleum Corporation — is one of the world's largest facilities processing ultra-sour gas. It processes about 1.3 billion standard cubic feet per day (scfd) of sour gas and associated condensates, which contain over 20 percent hydrogen sulfide and 10 percent CO 2. By 2025, modifications to the facility would enable the gases to be captured as part of the sulfur recovery process and converted into pure CO2 for enhanced oil recovery (EOR). Using advanced CCUS technology, more than 2.3 million tons per annum (120 million scfd) of CO 2 are planned to be captured and safely locked away underground.
