  Comparison of Liquefied Natural Gas Plant Unit Failure

  By Ukpaka C. P., Bani, S, L.

  Abstract: The comparison of some liquefied natural gas plant unit failure was investigated and the unit considered in terms of identification of the component failures. The units are Reboiler, Stripper, Cooling, Compressor, Acid Dehydration, Heat Transfer, Expander and Liquefaction units. The components of interest were monitored in terms of their performance as well as the failure rate of heat transfer unit > cooling unit > acid dehydration unit > stripper unit …

  Bioremediation of Polluted Drainage with Petroleum Hydrocarbon

  By Ukpaka C. P., Nwosi-Anele A. S, Chie-Amadi G. O., Chuku B.

  Abstract: This research was aimed at examining the petroleum product discharge in drainage within Port Harcourt City, samples were collected and mixed. Microbial analysis and physicochemical properties of the sample were determined. The sample was subjected into bioremediation after culturing of the microorganisms isolated, identified and characterized. The two microorganisms used are pseudomonas aeruginosa and aspergillus niger. The results obtained revealed high concentration for heavy crude oil than mixed crude oil; …

  Performance Evaluation of Azadirachta indica Leaf on Crude Oil Contaminated Soils

  By Eno O. N., Ukpaka C. P., Ademiluyi F. T.

  Abstract: The intention of this research was to ascertain the effectiveness of sun-dried and room-dried Azadirachta indica leaf at varying quantities, in the remediation of sandy and loamy soils contaminated with 100ml of crude oil. Gas Chromatography-Mass Spectrometry method was used to test for the physicochemical properties of the materials used for the experiment. The unpolluted loamy soil was observed to contain pH of 6.75, electric conductivity of 10.36µS/cm, Total Oxygen …

  Effect of Environmental Parameters on Metal Corrosion in Soil Using Finite Element Method

  By Ekpri N. I., Ukpaka C. P., Amadi S. A., Puyate Y. T.

  Abstract: Deterioration of buried metal due to corrosive soil environment is a major issue worldwide. Although failure of buried metal due to corrosive soil is an old problem, yet such failures are still uncontrollable even with the application of advanced corrosion protection technologies. Therefore, understanding environmental parameters causing corrosion of buried metals are necessary. This research work reviews environmental parameters causing corrosion of buried metal in soils. These functional parameters include: …
