Various technologies such as heat pump assisted distillation [3, 4, 5], distillation with vapor recompression [6, 7, 8, 9], distillation with bottom flashing [10, 11] and internally heat integrated distillation columns (i-HIDiC) [12, 13, 14, 15, 16, 17] have been developed previously for reducing energy requirements of distillation systems.
According to Keller and Bryan (2000), distillation is still a "formidable competitor" as a major separation method even though much research has been thrust on its alternatives.
There are around 40,000 distillation columns in operation in the US, requiring approximately 40% of the total energy consumption in US chemical process industries.

If vapor recompression, bottom flashing or heat pump assisted distillation systems are applied on the C1 C2 and/or C2 C3 distillation columns, extremely large values of compression ratio (~ 3 5) will be required for providing the possibility of heat transfer from the top product to the bottom one.
The P-9 distillation plant at Alabama was closed in June 1945, that at Wabash in July, and the one at Morgantown in August.
The configuration of 1G distillation was also updated to that used for 2G distillation, i.e. heat integrated with two strippers and one rectifier, including preheating of the feed streams using the bottom streams from the corresponding distillation columns.
Two fish were pooled for each protein determination and samples prepared using a Gerhardt KB40S digestion block and a Vapodest 40 distillation unit.
