Ad­noc mov­ing ahead with plans to ex­pand CO2 cap­ture

The Gulf Today - Business - - FRONT PAGE -

ABU DHABI: The Abu Dhabi Na­tional Oil Com­pany (Ad­noc) an­nounced that it is mov­ing ahead with plans to ex­pand the cap­ture, stor­age and util­i­sa­tion of car­bon diox­ide (CO2), pro­duced from ei­ther the Hab­shan-bab gas pro­cess­ing fa­cil­i­ties or the Shah gas plant. A de­ci­sion on which plant to cap­ture the CO2 from first will be taken in 2019. The pro­ject will be en­gi­neered so as not to in­ter­rupt on­go­ing pro­duc­tion from ei­ther fa­cil­ity.

The ad­di­tional CO2 cap­ture will re­duce Ad­noc’s car­bon foot­print - which is among the low­est in the in­dus­try - and lib­er­ate nat­u­ral gas, pre­vi­ously used for oil field in­jec­tion, for other more valu­able pur­poses, while si­mul­ta­ne­ously ad­dress­ing grow­ing global de­mand for oil by boost­ing re­cov­ery from its ma­tur­ing reser­voirs.

The an­nounce­ment was made at the In­ter­na­tional Car­bon Cap­ture Util­i­sa­tion and Stor­age (CCUS) Sum­mit, in Ed­in­burgh, by Omar Suwaina Al Suwaidi, AD­NOC Ex­ec­u­tive Of­fice Direc­tor, who led Ad­noc’s par­tic­i­pa­tion at the sum­mit. The event was at­tended by global en­ergy min­is­ters, chief ex­ec­u­tives and se­nior lead­ers from in­ter­na­tional oil and gas com­pa­nies, as well as the fi­nan­cial com­mu­nity.

The dis­cus­sion at the event is fo­cused on ac­cel­er­at­ing in­vest­ment in CCUS tech­nol­ogy, which has the po­ten­tial to sig­nif­i­cantly sup­port global CO2 emis­sions re­duc­tion, as well as un­lock value across economies, in­clud­ing in the UAE.

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 per cent hy­dro­gen sul­fide and 10 per cent CO2. 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 tonnes per an­num (120 mil­lion scfd) of CO2 are planned to be cap­tured and safely locked away un­der­ground.

Mean­while, the Hab­shan and Bab com­plex could cap­ture an­other 1.9 mil­lion tonnes per year of CO2 (100 mil­lion scfd). The com­plex can process up to 6.2 bil­lion scfd of as­so­ci­ated gas, mak­ing it the largest in the UAE and one of the big­gest in the Gulf.

Omar Al Suwaidi said, “Ad­noc’s ex­pe­ri­ence at Al Reyadah, the only com­mer­cial CCUS fa­cil­ity in the re­gion cap­tur­ing CO2 from a steel plant, gives us a ro­bust po­si­tion to build on our suc­cesses and ex­pand our CCUS ca­pac­ity, where com­mer­cially vi­able.”
