Computation of Biokinetic Parameters of Total Petroleum Hydrocarbon Degradation using Vernonia amygdalina StemBy Ukpaka C. P, Adaobi Stephenie Nwosi-Anele
Abstract: This investigation showcases the computation of biokinetic parameters of total petroleum hydrocarbon degradation using Vernonia amygalina stem as bio-stimulant for the remediation of contaminants in loamy soil environment. The research revealed decrease in TPH degradation with increase in contact time and the percentage reduction was computed. The result shows TPH (100 dosage) > TPH (75g dosage) > TPH (50g dosage) > TPH (25g dosage) > TPH (control sample) and the …

Monitoring the Operation of Mobile Air Compressor Component of Filters Using Reliability Analysis ConceptsBy Ukpaka C. P
Abstract: The performance of filter component was monitored in a mobile air compressor operating in a gas plant facility located in Rivers State. The investigation covers the monitoring of the numbers of failure, downtime, and computation failure rate, mean time between failure, reliability, unreliability, availability and unavailability. In this study, it was experienced that the failures occur due to over usage as well as presence of particles in the cooling fluid …

Experimental Investigation of the Production of Carbon(iv)oxide (CO 2 ) from Brewers Spent Grain using Anaerobic DigesterBy Ukpaka C. P
Abstract: In this study, fresh brewers spent grain from a Brewery in Port Harcourt, was used to generate biogas, and the rate of carbon dioxide production was examined as a fractional component of the biogas. Additionally, daily records of the anaerobic digestion process temperature and pressure buildup were recorded. The analysis result revealed that the pH values before and after the examination were 7.45 and 7.26, respectively, and that the temperature …

Simulation of Heat Generated on Crude Oil Degradation upon the Effect of Temperature in Bacteria Growth Kinetics in a BioreactorBy Ukpaka C. P, Okirie F. U.
Abstract: Model was established to simulate the heat generated by bacteria with the interaction of substrate (crude oil) degradation in a bioreactor upon the influence of temperature. The model was predicted by simulating the characteristics of bacteria interaction with substrate at temperature of 15oC, 30oC, 45oC, 60oC, 75oC, 90oC, 105oC and 120oC and heat generated is within the range of -1.0 to 7.1kcal/hr for bacteria in fresh water medium whereas for …
