Side Stripper Column
The side stripper is an additional alcohol recovery column connected to the rectifying column. Rectifier bottoms are pumped into the top of the side stripper column and steam and/or cook flash from the flash vessel is injected into the bottom. As the rectifier
bottoms fall through the trays, the steam rises and removes any remaining alcohol. The alcohol vapors from the top of the side stripper are carried back to the bottom of the rectifier column. Liquid from the bottom of the side stripper is pumped back into the cook system. Temperature at the bottom of the side stripper column is 85-88°C, whereas the top of the column is around 65-68°C.
