Invitation for Prequalification

This Invitation for Prequalification follows the General Procurement Notice for this project, which was published, on the EBRD website, Project Procurement Notices (https://www.ebrd.com/work-with-us/procurement/p-pn-181107a.html) on 7 November 2018.

GASCO, hereinafter referred to as “the Client”, intends, using part of the proceeds of a Loan from European Bank for Reconstruction and Development, hereinafter referred to as “the Bank” towards the cost of EGAS Energy Efficiency project, to extend capacity of existing Dahshour compression station by about 500 MMSCFD.

Dahshour existing compression station, commissioned in 2012, is composed of four turbo compressor packages (3 in operation and 1 stand-by), designed to receive 979 MMSCFD of gas from the national gas network at a pressure and temperature ranging respectively from 25.3 to 50 bara and 15 to 33°C, in order to pressurize the gas up to 71 bara, to be directed into the Assuit / Aswan pipeline via the existing Dahshour/El Koraimat 36″ P/L. Each existing compression train is consisting of one single-stage compressor driven by gas turbine, suction drum and after cooler. The gas outlet temperature from compression train is about 55°C.

Gasco has already planned to add one new turbo-compressor (train 5), two electrical motor driven compressor trains (train 6 A/B) and 2 x 50% Organic Ranking cycles to recover the waste heat energy from the existing and the new gas turbine.

The turbo-compressor Train 5 is sized to receive a feed of 326 MMSCFD @ 25.2 bara and 33°C @ battery limit, each electrical motor driven compressor trains (Train 6 A/B) is sized to receive a feed of 163 MMSCFD @ 25.2 bara and 33°C @ battery limit., the ORC is designed to recover the heat from 4 turbo-compressor simultaneously in configuration 2×50%, each ORC turbines, reference power 12 MW, is connected to two generators delivering electric power.

In order to meet the increasing demand, Gasco plans further Gas compression station extension. It will be a separate plant adjacent to the existing one.  It shall include the following items (or equivalent):

1. Adding one new turbo-compressor Train 7 sized to receive a feed of 326 MMSCFD @ 25.2 bara and 33°C @ battery limit,
2. Adding one new electrical motor driven compressor trains (Train 10A) sized to receive a feed of about 163 MMSCFD @ 25.2 bara and 33°C @ battery limit.
3. Adding one new ORC system installed to recover heat from turbo-compressor(s).  The ORC shall be sized to provide the power for the electric gas compressor 10A.

The ORC system shall be sized, designed and supplied to recover the waste heat energy by exchanging heat in the stack between the exhaust and thermal oil through a “Hot Thermal Oil Circulation System”, and then this heat is transferred to an ORC package. Organic Rankine Cycle (ORC) utilizes the heat energy in the GTG exhaust to heat an Organic fluid to a superheated vapor state in an evaporator.  The Organic fluid then expands in ORC turbine(s) connected to generator(s) delivering electric power. The organic fluid then condenses in an air-cooled condenser, and then is pumped again to the evaporator to complete the cycle. Recuperators, economizers, regenerators…etc. shall be installed in the ORC system, as deemed necessary by ORC supplier, to enhance the heat recovery effort.
