WHAT ARE THE MAJOR ISSUES IN A NEW BUILT GAS PROCESSING PLANT: LESSON LEARNED IN A LARG SCALE GAS PLANT IN IRAN

摘要

The 4~(th) gas processing plant (Phases 6-7-8) as a member of the South Pars Gas Complex(SPGC) in south of Iran, north of Persian Gulf is the largest plant in the world which has designed to treating and producing the dry sour natural gas for transfer and injection into Aghajari Oil Field in EOR projects. This large scale gas processing plant handed over to Operator Company (end user-SPGC) in the end of year 2009. Like other plants, the project transition phase from commissioning and start up step (by contractor) to full operational condition has had many challenges for both sides. One side was trying to close the project and cut the costs in a short time and other side was attempting to check and control of all processing requirements. Some of major issues for operator side such as; design shortages, construction punches, and performance problems were critical to pass through this transition zone and vice versa contractor had some other challenges in face of it. In this paper, all detailed challenges in hand over phase of this project has reviewed from both sides' point of view, and then the solutions, best practices and lessons learned studied. The results shows that a new road map for other gas processing plants should be developed which can provide a win - win condition for project parties.
