Pergas Projects 2008 - 2009: South Pars phases 15 & 16

The objectives of the development of these phases were as follows:


  • Producing 50 million cubic meters of natural gas per day.

  • Producing 80,000 barrels of gas condensate per day.

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

  • Annual production of 1 million tons of ethane as feedstock for the petrochemical industry.

  • Daily production of 400 tons of sulfur.


 Offshore and Onshore Facilities:


  • Two production platforms with 22 wells, two 32" submarine pipelines for transferring gas, 115 kilometres.

  • Two 4.5" pipelines for transferring MEG, 100 kilometre.

  • Gas sweetening units and related utilities.

The onshore refinery of this project was constructed in Asalouyeh, in the vicinity of phase 17&18. Pergas designed and built eight Absorber & Deethaniser sets , twenty-five Separator & KO Drum sets, sixteen Dryer & Reactor sets, forty-two Drums,twenty Titanium H/Exchangers and twenty-nine Heat Exchangers. These one hundred and forty sets were sold to Sepanir Oil & Gas Energy Engineering Co. who were a subcontractor in these phases.  The total weight of the hundred and forty sets was 7389  MT and  took 24 months to build and transfer to the project location
