1 Introduction

1.1 Background

RWE Dea Egypt has discovered seven natural gas reserves in the Disouq Concession within the onshore Nile Delta, starting in 2008, as shown on the concession map below. Further exploration in the concession is ongoing. RWE Dea Egypt is the operator of the Concession with EGAS as a partner.

The selected development comprises a central gas treatment plant near NSG-1x, where the gas is collected, treated by means of Low Temperature Separation utilizing the Joule Thomson effect to achieve gas quality, and compressed for export. Treated gas is transferred via a 16” pipeline directly into the GASCO NTS pipeline. The well fluids are gathered and fed to a common inlet separator at the central plant. All gases and liquids will be separated and processed on the central treatment plant into sales gas, stabilized condensate and free production water. Treatment of gas is carried out in two trains, while treatment of condensate is in a single train. Three trains of sales gas compression shall be installed. Fuel gas for the gas engine drive power generators will be taken from the suction of the sales gas compressors.

Main Electrical power shall be generated and supplied by two Gas driven generators 400 Volt, 3-phase, 4 wire, 50 Hz, 2000kVA each, with one generator running and one in standby. Both Gas driven generators will be connected to the 400 Volt AC, 50Hz Low Voltage Power Motor Control Centre (PMCC). One Emergency Diesel Generator 400Volt, 3-phase, 4 wire, 50Hz, 500kVA shall feed the emergency loads via the Low Voltage Emergency Power Motor Control Centre (EPMCC) in case of a loss of gas production.

One gas driven generator shall feed all plant loads with the second gas driven generator on stand by. Main electrical power with one gas driven generator running will be distributed via




Page: 6 of 32

the Power Motor Control Centre (PMCC) and the Emergency Power Motor Control Centre (EPMCC).

All generators (Gas driven and Diesel driven) shall have the ability to synchronize for maintenance purposes.

The PMCC and EPMCC shall be designed for the parallel operation of one gas driven and one diesel driven generator but not for continuously parallel operation of the two gas driven generators. Synchronisation of the both gas driven generators is purely required in case of maintenance of one gas driven generator set to prevent a production stop and to bring the second gas driven generator online before shutting down the one driven generator set.

A manual and fully automatic synchronization unit shall be installed on each power generation skid. Central Treatment Process Plant loads will be connected with the Power Motor Control Centre, the Emergency Power Motor Control Centre and the UPS distribution panel as shown on the Single Line Diagrams MCC, PMCC, EPMCC and UPS (1007-DISQ-0-G-DW-30089).

Preliminary Process Plant loads as result of the FEED are shown on Electrical Load List (1007-DISQ-0-G-LL-30090).

One gas driven generator as main and normal power supply will feed process plant loads such as:

Motors.

Package units.

Buildings normal lighting distribution panels and welding socket outlets in the

Workshop, Warehouse, Control building, Fire pump station, Substation

building and chemical storage building.

External lighting distribution panels.

Control building UPS. (located in Control Building)

Compressors UPS. (located on Compressor Skid)

Flare UPS (Located near the Flare)

Plant loads are preliminary estimations as result of FEED design and will be finally determined during detail design by the detail design contractor and the vendors of packages..

In Normal operation with the one gas driven generator running the emergency loads shall be fed via the PMCC and EPMCC. In case of loss of this normal supply, the emergency diesel generator shall start automatically to feed the emergency loads of the process plant only without black out.

The Emergency power motor control centre shall feed the emergency plant loads as shown on the single line diagrams“1007-DISQ-0-E-DW-30089”.

Preliminary Emergency plant loads are shown on electrical load list “1007-DISQ-0-G-LL-30090”.

1.2 Objective
