[Gasification] Gasification Digest, Vol 29, Issue 7: scrubber water

[Tom Miles]

>How were they handling the scrubber water, Tom? A colleague visited a
reasonable size gasifier in Europe where the water was stored in a tank.
Once this tank was full their immediate option was to install another tank.
Not ideal!

There are many plants that haven't figured out how to deal with the scrubber
water short of paying someone USD $0.70-$1.50/gallon to treat it. Some
systems make less water, use recovered heat to concentrate the pollutants,
and either recycle the pollutants as solids to the gasifier and/or use part
of the gas to burn out the residual moisture and pollutants. The cost is
lower net conversion to heat and power. The benefit is being able to convert
fuels that re otherwise difficult to burn or gasify.
