Heat Exchanger Integration and Analysis of Minimum and Maximum Energy Needed Using Pinch Technology: A Case Study in Bahir Dar Textile S.C, Ethiopia
Global energy demand and environmental pollution due to the emission of greenhouse gas is the main problem of the world. In Ethiopia, the demand for
energy is rising due to industrialization. The main application of pinch technology is optimizing the design of heat exchanger networks to get energy targets (minimum and maximum energy needed to operate the overall utilities). Finding the energy shortage through energy audits and integrating it with surplus energy supply is one of the basses of this technology. As per the analysis of this study, the thermal data for heat exchanger was collected from Bahir Dar textile factory. By considering a suitable temperature difference between hot and cold streams and by constructing the composite curves, the pinch point was evaluated. Aspen HYSYS software was employed for designing of heat exchanger network. Finally, the maximum energy of the cold stream utility at the textile factory was estimated at 287.3 kJ/h.
