Production Equipment/Fuel Ethanol Equipment
Alcohol distilled ethanol production line, Ethanol distiller
Ethanol distillation equipment
1. It is a turn-key whole set equipment, simple equipment, less
worker, less area, less cost.
2.We can use corn, wheat, cassava, molasses, rice, potato, chinese
date, beetroot,sugar cane ect which contains starch or sugar
material to produce ethanol/alcohol.
3. We can do the turn key system or section part.
4. We can improve and rebuild old alcohol(ethanol) production line
You can choose single distill tower to save money, also can choose
2 or more distill column to get good quality alcohol(ethanol).

Distillation is one of the most common liquid-liquid separation
processes, and can be carried out in a continuous or batch system.
Distillation works by the application and removal of heat to
exploit differences in relative volatility.
The heat causes components with lower boiling points and higher
volatility to be vaporized, leaving less volatile components as
Mixtures with high relative volatilities are easier to separate.
This makes separations of close-boiling and azeotropic feeds
difficult, so special distillation techniques have to be used to
separate these mixtures.
Ethanol production line three-column differential pressure distillation
The differential pressure of the process unit is: the differential
pressure between rectifying column T502 and beer stripping column
(mash column) T501, aldehyde column is for atmospheric
1,The fermentation mash from fermentation section is preheated to
70 ℃ through primary preheater E502 (Fermentation mash is preheated
by crude alcohol vaporcondensed at the top of the mash column),
secondary preheater E507 (Fermentation mash is double preheated by
waste distillers in mash column), and feed into the mash column at
the 24th tray.
Mature mash is heated by the bottom steam when downward in the mash
column T501, alcohol vapor is upward and separated from the waste
Waste mash is discharged at the bottom of the column, and the
alcohol content of waste mash is no more than 0.05% and transported
to the environmental protection section.
Upward crude alcohol is for defoaming (low concentration alcohol)
by 25th, 26th defoaming plates and enters into 1 # preheater, part
of the alcohol vapor is condensed, uncooled alcohol vapor continues
to be condensed by a set of condenser.
The condensate liquid is heated indirectly by steam condensate
water and residual distilling water (waste water at the bottom of
the column) of rectifying column and enters into the aldehyde
Part of the crude alcohol is reflux (the purpose is for defoaming
the crude alcohol gas), while some non-condensing gas is discharged
into the atmosphere through the vacuum pump.
Heating mode of mash column: the alcohol vapor at the top of the
rectifying column heats the mash column through the reboiler E501,
The reboiler uses a circulating pump for circulation.
The mash column works under the negative pressure, the negative
pressure is produced by the connection of the vacuum pump through
the bank of condensers.
2,Aldehyde column works under the atmospheric pressure.
Condensate liquid (crude alcohol) from mash column is indirectly
heated by the steam condensate water, enters into the aldehyde
column at the 16th tray.
The head impurities such as aldehydes and esters move upward to the
top of the column.
After condensation, most of the alcohol vapor at the top of the
column will reflux, and a small part is extracted as industrial
Low boiling point gases such as aldehydes and esters and
non-condensable gas are discharged into the atmosphere through the
After separation, the light alcohol at the bottom of the column is
relatively pure, and enters into the rectifying column after being
preheated by the residual distillation water (waste water at the
bottom of the column).
Heating mode of aldehyde column: is directly heated by the fresh
steam and the flash steam.
3,Light alcohol from aldehyde column T503 is indirectly heated by
the residual distilling water of rectifying column, enters into the
rectifying column at the 18th tray.
While the light alcohol is gradually concentrated, head impurities
such as methanol and aldehyde are upward with alcohol vapor to the
top of the column, part of impurities (such as oil) is retained on
the upper layers of the feed plate whereby as fusel oil produced
into the fusel oil separator for oil and alcohol separation.
Fusel oil enters into fusel oil storage tank V509, and light
alcohol enters into light alcohol tank and is pumped to the
fermentation mash tank.
The head impurities can be removed by extracted part of the reflux
as industrial alcohol.
The alcohol with a concentration of 95-96% (v/v) in the 6-8 trays
below the reflux mouth of the column top is extracted as the
finished product, and after cooling, the high concentration alcohol
enters into the finished product alcohol tank.
Heating mode of rectifying column is heated indirectly by fresh
steam through the rectifying column reboiler, and the condensate
water is flash steamed and sent to the crude alcohol preheater by
the condensate pump for exchanging heat with the crude alcohol and
then return to the boiler room for reuse.
The flash steam is used as part of the heat source of the beer
1,Standard: alcohol GB10343-2002 "alcohol" level standard
2,General layout: the alcohol plant design specification QB6014-96
4,Non-standard equipment production standards or industry
standards, or both parties approved drawings.
Packaging & Shipping
1. small parts use wooden box, large equipment use plastic film.
2. Columns are fastened with iron support.
