Hello

Our company is currently trying to obtain/ make a pilot rig to undertake counter current mass transfer on a new random column packing we have developed.

We currently have no technical information and are unable to provide our customers with the technical data they require.

The packing is much smaller than the common random column packings (1.5mm,3mm and 6mm ), have exceedingly low pressure drop along with high efficiency (Mass transfer coefficient) with a surface area of 2378m2/m3 (calculated for our rings by 3rd party)

We require a rig in house to undertake measurements to fully characterise the rings to provide required data to customers as well as ongoing tests and research.

Random column packing is a new industry for us and we have little prior knowledge as to what performance characteristics are required.

From initial research we believe we need to measure the following through a range of conditions.

· Pressure drop correlation

· Dynamic and Static Liquid hold up

· Mass transfer coefficient /(HETP)

· Flooding point (Pressure drop at Flooding)

· Minimum liquid rate for wetting

We would greatly appreciate some advice as to whether these characteristics are what is recommended within the Industry for Counter Current Mass transfer to fully characterise the packing and some advice on a suitable rig set up and detector other than a spectrometer


Are there any books/websites that you can recommend for this?

We are a CHE premier member if that helps to recommend anything

Thank you for your help

Without mystifying the fractionation process, I'd say you have already gotten the most (if not all) of the data required for comparison between different manufacturers. What I can suggest further is to visit their websites (Koch-Glitsch, Sulzer, ACS) and see what they offer - as far as structured and random packing are concerned. In addition, you may want to obtain a membership in the FRI (Fractionation Research Institute: http://www.fri.org/) and get their advices as well.
