evaporating tanks? 3

[NCCaryME]

Please forgive an ME trying to solve a ChemE problem...

Does anyone have any experience with using an evaporation process to remove water from a solution. The solution is approximately 65% water, 30% sodium silicate, and a handful of other solutes. I need to remove half of the water from the solution. Is evaporation a logical way to do this? If so, can someone point me towards a process or manufacturer?

Thanks in advance.

Come back with a little more details.

What capacity do you need?

What would be your heat source?

Evaporation is a logical way to do it, assuming you have a heat source to do the job.

However, without knowing more about your overall situation, most of us are not going to be able to give you much advice.

Can you tell us if you use steam in your plant, or process, and if there is any low pressure waste steam available, or other waste heat available? Otherwise, you are going to have to pay $$ to get the btu's to do the evaporation. This is the kind of evaluation you are going to have to make. But, we need more info to help you with your decision.

There is a possibility that we could pump ~400 F thermal oil used at another process on site, otherwise we would need a stand-alone heat source (electric, gas-fired boiler, etc.). Operating cost is not a huge concern as this will be an intermittently used process. Batches would probably be around 500-1000 gallons of solution.

you could send an enquiry to EBNER

They supply evaporation plants and vaporization plants.
