Expansion & Enhancement Projects

Dakhni Expansion Project
The Dakhni gas processing plant was commissioned in 1989 with a design capacity of 30MMSCFD per day of sour feed gas. Over its years in production, the composition of H2S contents in the raw gas has significantly increased, resulting in limited production capabilities. Most of the equipment /packages of Expansion Project received at site have been installed by OGDCL with its own resources at the current production has been increased to the tune of 52 MMscfd (i.e. 30 sweet gas + 22 sour gas) whereas, work on the installation / erection of Sulphur Recovery Unit (SRU) has been started by the PCC Contractor M/s EKL and the unit is expected to be installed/commissioned by February 2012, which will further enhance the production of sour gas from the field.

Relocation Of Pirkoh Compressors
OGDCL is operating Qadirpur Gas Field located at a distance of about 80 km from Sukkur, Sindh Province of Pakistan. The field has been in operation since 1995. The reservoir pressure of the field is gradually decreasing due to continuous production. To arrest the decline in reservoir pressure and maintain the production plateau, compression facilities are required for optimum recovery of gas

In the view of above, as a first step, OGDCL has installed fourteen (14) reciprocating compressors at Qadirpur Gas Plant. This will be followed by the installation of three (03) Turbine Driven Gas Compressors relocated from the Pirkoh Gas Plant.

Two Turbine Driven Compressors have been shifted from Pirkoh and are available at Qadirpur. The construction of foundations has been completed. The refurbished turbine cores from OEM, M/S SOLAR USA have been received and installed. The “Overhauling of Compressors”, is in progress in the premises of New JCM China. The procurement of balance of material is in progress. The contract for “Installation, Commissioning & Start-up Assistance” has been awarded to M/S KRL. The project completion is being completed on fast track .

Permeate Compressors
There are two Permeate Gas Compressors manufactured by M/S GE/NP, Italy for compression of permeate gas for recycling purpose. Due to gas field expansion, which consequently, resulted in more flow of permeate gas as well, OGDCL has procured two additional Turbo-Compression units of 27-32 MMSCFD capacity each. These Turbo-Compressors are procured from M/S MAN Turbo Germany, who has also provided technical supervision services during installation/erection and commissioning. Both compressors have been commissioned, 1st in August, 2011 and the 2nd in December, 2011. By completion of this project, uninterrupted supply of permeate gas for IPP and gas distribution company, has been ensured.
