Petrobakr Petroleum Company which is a key Egyptian joint venture between the Egyptian General Petroleum Corporation (EGPC) and Vaalco Energy, focusing on oil and gas exploration, development, and production in Egypt. The Company intended to do an Energy Sources and Emissions Study. Diar Consulting Group has been invited to undertake the engineering services for that Project.
I. Process Engineering
The primary objective of the process team during the site visit was to:
· Identify and locate all generator set positions
· Determine the locations of LPG storage (tank or truck) and CNG supply points
· Identify and trace the natural gas pipeline routes for various operational scenarios
Station Configuration
K Station:
o Installation of one large generator to supply both the K Power Station and the associated water handling facilities
H Station:
o Installation of one large generator to supply both the H Power Station and the associated water handling facilities
Study Scenarios
The study will evaluate the following fuel scenarios:
· A. Bi-Fuel: Diesel + Natural Gas (NG)
· B. LPG: 70% Butane / 30% Propane
· C. CNG: Primarily Methane
· D. Natural Gas (NG): Primarily Methane (Tie-in pressure: 70 barg)
Key Assumptions & Data
In the absence of detailed gas composition analysis:
o NG and CNG will be assumed to be pure methane
o LPG composition is assumed as 70% butane and 30% propane
The calculated load will cover only:
o Power stations
o Water handling systems in both K and H areas
New generators will be installed at the same locations as existing power stations
Gas Supply & Distances
· Proposed gas pipeline tie-in point is approximately 11 km from the K & H locations
· distances:
o Distance to H Area: ~4.8 km
o Distance to K Area: ~5.0 km
II. Electrical Engineering
The main objective of the Electrical team during the site visit was to collect and analyze data to fully understand the existing power system, including:
· Current power supply configuration
· Load distribution across the facility
· Details of existing:
o Generators
o Transformers
o Distribution stations
Key parameters gathered:
o Equipment capacities
o Locations
o Demand load values
Additionally, the team evaluated alternative energy supply scenarios to enhance system reliability and efficiency.
