Gas treatment unit to be located in Gabes governorate

Engineering, procurement and construction (EPC) contracts have been awarded for the $800m Nawara gas field development project in Tunisia.

A joint venture between local Bouchamaoui Industries and Germany’s Max Streicher has been appointed as the main contractor for the gas pipeline and central processing facility (CPF) package, while a joint venture between Switzerland’s ABB and Canada’s Thermo Design Engineering has won the contract for the second package, which involves the construction of a Gas Treatment Part.

The front end engineering design (FEED) contract for the pipeline and CPF package was won by the British firm, Petrofac and the FEED for the gas treatment plant was won by Italy’s Saipem.

The Nawara gas field development project is a joint venture between the Austrian integrated oil and gas company OMV and the Tunisian National Oil Company Entreprise Tunisienne d’Activites Petrolieres (Etap). Each entity has a 50 per cent stake in the project.

The project is slated to produce gas for the domestic Tunisian market. 

The gas treatment unit is going to be located on a 35 hectare plot located in the Gabes governorate industrial park.

The plant will be designed with an initial processing capacity of 4 million cubic metres a day, which may be increased up to 10 million cubic metres a day.

The gas will be conditioned for sale, whereas the condensate (LPG) will be recovered to produce commercial propane and butane.

The design of the gases treatment unit will go through the following stages: 

  • Site preparation, clearing access paths and building of the premises
  • Installation of the storage surfaces and layout of the rain water supply network, the drinking water supply network, the sanitation network and the electrical supply network
  • Installation of heavy equipment

The scope of the work will include :

  • Unit for the reception of gas (thriphase separator)
  • Mercury dehydration and elimination unit
  • NGL recovery unit and GPL fracking unit (of the columns)
  • Commercial gases compression unit
  • LPG storage and shipping unit and forwarding and stabilised condensate storage and shipping unit
  • End products tax measuring units
  • Associated facilities
