Abstract
Heat exchanger design and cost optimization had been carried out for Pabod Brewery, Port Harcourt, Rivers State, Nigeria using Pinch Technology as process application method. The gross energy expenditure by the plant is 10.44MW at production capacity of 400,000 liters of beer per day. On quantitative aggregate 6.157MW goes for heating and 4.267MW for cooling. A temperature pinch or minimum approach temperature (?Tmin) of 100C, minimum heating utility of 5.04MW and cooling utility of 3.09MW were recorded. Energy upturn of 1.08MW and 1.23MW for the hot and cold flows were measured. This finding correlates to energy conservationS of 18% for hot utility and 21% for the cold utility. Overall improvement in capital and annualized costs of 39% was achieved for the hot and cold utilities. The researchers strongly recommend the outcome of this research to process applications in brewery, chemical, petrochemical, oil and gas industries.
