The Impact of Engineering Design on the Performance of Heat Exchangers in Various Applications in Iraq

Abstract

This work examines between engineering design and heat exchanger performance under particular and severe operating conditions in the Iraqi environment. The local conditions include summer temperatures of more than 54 °C in the south, high levels of dust, and highly saline sources for cooling water (in the Shatt al-Arab, up to 15,000 mg/l), which subjected industrial cooling solutions and their efficiency to unprecedented strains. The study discloses a significant disconnection between typical international design guidelines and the real performance of imported machinery, leading to as much as 40% degradation of thermal efficiency and substantial monetary losses attributed to unanticipated downtime and increased fuel usage. As methodologies for systematic approach, the study demonstrates the potential of using advanced methods such as computational fluid dynamics (CFD) modelling and simulation to design barriers and fins, as well as high-performance materials like titanium alloys and 316L stainless steel, to mitigate scaling phenomena and resulting accelerated corrosion. Furthermore, it is demonstrated that in the presence of smart cooling technologies based on Internet of Things (IoT) together with waste heat recovery (WHR) systems, a decrease in energy consumption up to 18 % with a remarkable reduction in carbon emissions can be achieved. The study states that the sustainability of oil and energy production in Iraq and enhancing national energy security depends on the need to move away from conventional design processes to data-centric engineering that
