Influence of the Filling Oil Compounds and Additiveson the Thermal Stability of Insoluble Sulfur

Heat transfer enhancement technologies have witnessed a rapid growth in recent years. Passive process intensification methods are a very effective tool to reduce the size of heat exchanger equipment or to enhance the capacity of existing units. This is achieved by means of turbulence promoters of different geometries. This turbulence promoter affects the heat transfer process and the pressure drop. In this paper, turbulence promoters used under turbulent regime are analyzed based on the thermal improvement factor (η). This factor gives an indication of the improvement in heat transfer and pressure drop and provides the means for a reliable performance comparison and selection
