Performance of packings for water distillation

Abstract
Distillation of water has been investigated in packed columns of 300, 500 and 750 mm diameter. Both ordered packings (Goodloe, Mellapak and Sulzer CY) and random packings (Hy‐Pak, Mini‐ring and Pall‐ring) were studied and performance compared. It was found that, with surface treatments, phosphor bronze packings show good performance and insignificant scale‐up factors. Plastic materials are not suitable for water distillation because of their poor wetting characteristics.
