HI Everyone

Working in a ethanol distillation plant is obviously important to continuously monitor the concentration of the product distilled. In our case we distill at a constant 190 Degrees Proof (95% v/v). The current method to monitor this concentration in my facility is by the use of the hydrometer.

The uses of coriolis meters that can measure density, mass flow, and temperature are common now in this type of industry to use them to directly correlate these parameters to give final volume concentration with great precision.  

My knowledge in instrumentation its limited, that’s why I come to you guys for some recommendation.

Have anyone have any experience working with this kind of system before? I know you can program the meter transmitter with the Density – Temperature to concentration tables so be able to monitor directly the concentration of the fluid. The problem is that I have only found this table to fix the density up to 100F but for my application temperature of up to 220F will be needed and I have not foun data to compensate density using temperature for these high temperatures.

 

What would be a method to be able to directly read ethanol concentration?

 

Thanks in advance

I would check with the instrument supplier.

Hi ,

Let you consult this supplier :http://www.anton-paa.../density-meter/

Hope this helps you out.

I have done this successfully before.  If the coriolis meter supplier cannot provide the programming contact me via my signature below.
