SO3 Scrubber & Demister

SO3 Scrubber & Demister

SO3 Scrubber & Demister

We have to define some installation to treat gas effluents from sulfonation reactors.

Typical components in the gas stream are H2O, Formaldehyde, SO3, N2, O2 and some Phenol .-

The initial approach includes a scrubber with water or a caustic solution to absorb some of the components and a demister to remove the acid mist produced in the scrubber.

I would like to know your experience in this area.


RE: SO3 Scrubber & Demister

Ardilesd, I have no direct experience on the subject, but have seen drawings on flue gas treatments showing demisters being spray-washed from below and from above with water located in the same vessel just above the scrubbing section. The selection of the neutralizing chemical appears to be of economic (effectiveness vs cost) importance.

RE: SO3 Scrubber & Demister

Thanks, my friend from Quitilipi!
I have been in contact with Koch and EnviroChem, and the solution seems to be similar to that you describe.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.
