South Pars Gas Field Development - Phases 17 & 18

The EPC contract for the development of phases 17 & 18 was awarded to a consortium of IDRO, OIEC and IOEC. OIEC and IDRO are responsible for the onshore section and IOEC for the offshore facilities including platforms and subsea pipelines. The offshore facilities of phases 17 and 18 are 100 kilometers away from Assalluyeh. Two production platforms with 22 gas wells form the core of the project. The project also entails two 32" pipelines for transferring gas and two 4" pipelines for MEG. The onshore refinery of phases 17 & 18 is located alongside the facilities for phases 9 and 10. The refinery consists of four gas sweetening units, condensate stabilization unit and corresponding storage tanks, sweetening, dehydration, refrigeration and separation units for Ethane, Propane and Butane, gas de-mercaptanization and compression unit, Sulphur recovery and granulation unit and Mono Ethylene Glycol regeneration unit.
