Abstract:
Global energy crisis has been on the increase due to increase on energy demand driven by population growth. In attempting to address the global energy crisis, this work uses the alternative resources to diversify the conventional energy sources in order to supplement the available energy generating sources. Energy resources are being evaluated to supplement the conventional energy sources thereby boosting the total energy generation in a nation. Technical and economic models are developed and used to evaluate the energy values in natural gas fractionation. Natural gas fractions evaluated include liquefied natural gas (LNG), liquefied petroleum gas (LPG) and condensate (liquid fuel). Collated field data are inputted into the developed economic models to estimate feasible technical and economic values in each of the gas fractions. The technical and economic analysis revealed that bulk natural gas contains 85.76% liquefied natural gas, 11.61% liquefied petroleum gas and 2.28% condensate (liquid). The result also revealed that natural gas fractionation improves its economic and energy values. With this, it is clear that the improvement in natural gas energy sources has the potency to supplement, hydro-electric power source, coal power source, oil and/or diesel fuel power sources.
