Pergas Projects 2006 - 2007: South Pars phases 9 & 10

The development plan for phases 9 & 10 has been designed to produce 56 MMscm/d from the reservoir. The project was implemented in the following way.


The objectives of developing phases 9 and 10 were as follows:


  •  Daily production of 50 MMscm/d of natural gas.

  •  Daily production of 80,000 bl of gas condensate.

  •  Annual production of 1 million tons of ethane.

  •  Annual production of 1.05 million tons of liquid gas, butane and propane (LPG).

  •  Daily production of 400tons of sulfur.


Offshore Facilities:


  • Two offshore gas production platforms with 24 gas wells, some 105 kilometers from the main land.

  • Two 32" submarine pipelines for transferring gas to the onshore refinery.

  • Two 4.5" pipelines for transferring Glycol.


Onshore Facilities:


  • Gas and condensate receiving and separation unit.

  • Gas condensate stabilization unit, gas sweetening and dehydration unit.

  • Natural gas, ethane, propane and butane cooling and separation unit.

  • Demercaptanization unit and Gas compression unit for being transferred.

  • Sulfur recovery and granulation unit; and  MEG recovery unit.

The project for development of these phases was awarded to a joint venture of GS of South Korea, Oil Industries Engineering and Construction Company (OIEC) and Iranian Offshore Engineering and Construction Company (IOEC), in September 2002. The share of Iranian contracters in these projects exceeded 60%. 


Pergas designed twenty-two Separator & KO Drum, these twenty-two sets were sold to LG E&C (

who were a subcontractor involved in these phases .The total weight of the twenty-two sets was 464  MT and took 12 months to build and transfer to the project location.


Pergas also designed eighteen Heater & Pre heaters, these items were sold to OIEC ( The total weight of the heaters was 781 ton and built and were transferred in 18 months.
