Energy, exergy, environmental and economic analysis of industrial fired heaters based on heat recovery and preheating techniques
Fired heaters are ubiquitous in both the petroleum and petrochemical industries, due to it being vital in their day to day operations. They form major components in petroleum refineries, petrochemical facilities, and processing units. This study was commissioned in order to analyze the economic bene...
