Mitigation of Shell-Side Liquid Maldistribution in Coil Wound Heat Exchanger Bundles

Mitigation of Shell-Side Liquid Maldistribution in Coil Wound Heat Exchanger Bundles

Described herein are coil wound heat exchangers (CWHEs), and methods of cooling and/or liquefying streams of fluid using said CWHEs, in which one or more tube layers of the tube bundle are provided with a non-uniform tube winding angle and tube pitch in order to facilitate the equalization of radial...

Zusammenfassung:Described herein are coil wound heat exchangers (CWHEs), and methods of cooling and/or liquefying streams of fluid using said CWHEs, in which one or more tube layers of the tube bundle are provided with a non-uniform tube winding angle and tube pitch in order to facilitate the equalization of radial pressure imbalances on the shell side of the CWHE, thereby reducing radial maldistribution of fluid on the shell side and improving the heat transfer efficiency of the CWHE.
