A data-driven model for the air-cooling condenser of large-scale coal-fired power plants based on data reconciliation and support vector regression

François Maréchal, Ivan Daniel Kantor, Ligang Wang, Xiang Li, Jean-Loup Sylvain Robineau

The performance of a direct air-cooling condenser under operation is rather complicated, as it is interactively affected by the operating conditions (e.g., the mode of air fans) and ambient conditions (e.g., temperature and wind speed). To understand the c ...

Role of total site integration in energy-target modification of distillation columns

François Maréchal, Nasibeh Pouransari

This paper investigates the energy efficiency improvement of an industrial site through thermodynamic analysis of distillation columns together with the total site integration (TSI). Unlike the existing methods which consider the distillation unit exclusiv ...

Flow boiling data and prediction method for enhanced boiling tubes and tube bundles with R-134a and R-236fa including a comparison with falling film evaporation

John Richard Thome, Eugene van Rooyen

New enhanced boiling tubes from Wolverine Tube Inc. (Turbo-B5) and Wieland-Werke AG (Gewa-B5) were investigated using R-134a and R-236fa as test fluids. The tests were done at saturation temperatures of 5 and 15 degrees C, mass flow rates from 4 to 35 kg m ...

Evaluation of advanced technologies based on integration techniques - Application on dividing wall column

Seifeldine Ahmed Fathalla

In order to separate a mixture into high purity products, Dividing Wall Distillation Columns (DWCs) have shown to be, in most cases, more convenient than using conventional distillation column sequence. In fact in DWCs the entire separation task occurs in ...

Falling film evaporation on enhanced tubes, part 1: Experimental results for pool boiling, onset-of-dryout and falling film evaporation

John Richard Thome, Marcel Christians

Horizontal falling film evaporators have the potential of displacing flooded evaporators as the standard in the refrigeration industry due to compelling advantages, such as smaller refrigerant charge and lower pressure drop. However, there is a need to imp ...
