  Modelling and Simulation of a Bio-Fermenter for Ethanol Production

  By Chukwuemeke. P Ukpaka, Ekperi N. I.

  Abstract: Industrialization and world population are continuously increasing and this demands high energy. Ethanol is one of the leading bio-fuel in recent years. In this research, mathematical models were developed to monitor, predict and simulate the rate of production of ethanol from the fermentation process of corn. Increase in the ethanol production was observed within the range of 0 >D_S≤0.25 of solvent dilution rate with the optimum value of ethanol concentration …

  A Predictive Model on Pipeline Corrosion

  By C. P. Ukpaka, Ekperi N. I.

  Abstract: A comprehensive mathematical model is developed to predict corrosion rates in pipeline. The specimenused for this design is coupons (mild steel). Four containers with different solvents of 0.5 concentrationof nitric acids, 0.5 concentration of HCl, fresh water, and saltwater respectively were provided, andthe four paired coupons were placed inside the solvent for seven days. Each day, the coupons wereremoved, washed, dried, weighed, and placed back into the solvent. The result …
