HEAVY WATER PRODUCTION BY NATURAL WATER DISTILLATIONⅢ. WETTED-WALL COLUMN DEVELOPMENT

摘要

The development of a wetted-wall type of packing which would be suitable for heavy water production by natural water distillation is described. A series of parallel vertical aluminum sheets has been found to be the most satisfactory type. The sheets were fabricated in structurally strong units which would be suitable for packing a large distillation column.nTests made on sheets 6 inches by 24 inches by 1/16 inch thick assembled in units of 6 inch square cross section show that 1/4 inch spacing between sheets allows the highest through-put before flooding. Tests in a 4 foot air-water column gave the following results for 1/4 inch spacing;
