Abstract
Electrical energy supply has been a problem for a long time in Nigeria, especially in the Northern States where alternatives like natural gas are not available. A complete analysis on the capacity under utilization of the industries in Kano and Kaduna was carried out and found that only 41.24% of the required power is supplied to these locations as at September 2005. The remaining 58.76% will have to be provided by other sources of power generation mostly by the use of generators. While this energy crisis is taking place, a large volume of natural gas is flared in the Nigerian Niger delta area with around 2.5 billion scf, being flared daily representing an annual economic loss to the country of about $2.5billion. This work reports on the design of gas pipeline extension from Ajaokuta-Kaduna-Kano. Trunk Gas Pipeline cost and some aspects of Engineering Design were carried out in using Geographic Information System (GIS). The important design parameters obtained are the volume of gas flow rate per day Q as 2.1573 *107 ft3 /day, total pipe length was 552.024 km while the pipe internal diameter was found to be 16.4inches. The nominal wall thickness and stresses inside the pipeline was found to be 0.36 inches and 27963.1336 psia respectively, while the design pressure was 740 psia. The total cost of laying the pipeline was found to be N20.08 Billion representing N16.73 Billion as plant facilities and N3.35 Billion as working Capital. The rate of return on investment was found to be 30% per year.
