Application Story – Bio-Ethanol Production in US & Canada<br />
Fuel Ethanol (200 Proof) is a renewable, clean<br />
burning & high octane fuel that is better for the<br />
environment than gasoline. It is also biodegradable<br />
and far less toxic than fossil fuels<br />
and can be used on its own (E100) or blended<br />
<strong>with</strong> gasoline (E10, E85 etc).<br />
Ethanol can be produced from starch/sugar rich<br />
feed stocks such as grains/cereals (corn, wheat,<br />
rice etc) , potatoes, cassava, beet/sugar cane and<br />
today even from cellulosic biomass sources viz.<br />
wood chips, switch grass, corn stover's, municipal<br />
waste, recycled paper etc.<br />
Of all these feed sources the Dry Grind/Milling<br />
process used for corn (or wheat) feed is the most<br />
popular in US & Canada. Typical <strong>OPTIMASS</strong><br />
applications on a Dry Grind/Milling process<br />
(shown on right) include density measurement for<br />
slurry tanks , liquefaction mash, syrup draw ,<br />
rectified & final proof measurements.<br />
Slurry #1 Density ( Slurry Preparation)<br />
Combined Flow/Density measurement using<br />
our <strong>OPTIMASS</strong> 7000 series (S50 straight<br />
tube) on the evaporator syrup draw<br />
application (shown below) provides a high<br />
investment return by improving the overall<br />
dryer process efficiency downstream of the<br />
evaporators.<br />
Evaporator Syrup Draw<br />
STRAIGHT TALK<br />
<strong>Krohne</strong> Inc has over 60+ installation ( and 50 more on order) of<br />
<strong>OPTIMASS</strong> 7000 series (S25/S50 tubes) on the corn<br />
slurry/mash & syrup applications . Additionally on each of these<br />
plants our 7000 series (S15 tubes) are installed on liquid<br />
ammonia feed lines that feed nutrients into the slurry tanks and<br />
fermentors.<br />
Liquefaction Mash<br />
(feed preparation for fermentors)<br />
Corn Slurry and syrup drawn from evaporators<br />
can be extremely nasty & viscous and will clog<br />
almost any bent tube designs - it is here that<br />
the single straight tube Optimass offers<br />
significant benefits.<br />
Also lower pressure drop is a desirable feature<br />
as energy optimization is of utmost importance<br />
on these high energy intensive processes. It<br />
are for these reasons that <strong>Krohne</strong> is able to<br />
demonstrate value over our competitors.<br />
