Re: Laboratory Testing Of A Catalyst Handling System
Your project is of interest to us having many years experience in the design of pneumatic conveying systems handling a wide range of products.
We are also geographically, quite close to you as we are based in Wrexham, North Wales.
If you consider I could be of assistance to you then please contact me.
Regards,
John Hughes Lloyd.

Pilot Plant
Dear friends,
You have not stated whether your system operates in hot or in cold conditions (temperature of solids and gases). I will be very glad to help you.
I designed and built the HYL pneumatic conveying pilot plant, designed for obtaining scale-up data for the pneumatic conveying of iron/ore and hot sponge iron, all the way up to 700ºC.
If this is going to be a pilot plant, you should not worry about wear, nor about oxidation of pipeline, otherwise you will run into very high costs.
Another question.
Are you concerned with the degradation of the catalyst, or is this going to be a minor concern?
Cost and appearance.
Should this pilot plant look well (customer will see it), or will it only be used to obtain scale-up data?
Your instrumentation.
Do you have transducers available, multiplexer, and data acquisition systems, or do you want to use registers?
How big do you want this built?
Is your particle very small or very large?
How many bends do you want to have?
How near the bends?
All these questions you have to answer before building your pilot plant.
I will be more than glad to help you out, but I will not build your pilot plant. I will certainly assist you to build it, if you wish.
I would think that a 3-day visit to your installation will be more than enough to get you started, but I am not located in Wales, I am in Mexico.
The other alternative wil be to send me an e-mail with your data and a confidentiality agreement, so that we could work together through the internet.
My fees are reasonable and will depend on what the task is.
You can either contact me here through my e-mail, or through Paul Solt, Pneumatic Conveying Consultants (pccsolt@enter.net), who is a very good friend of mine, and a business partner.
He was, by the way, Fuller Company's R & D Manager before it became part of F.L. Smith.
He designed and built Bethlehem's Fuller pilot plant.
He now leads Pneumatic Conveying Consultants.
So if you are interested in data acquisition and scale-up techniques, but not in construction, I thin we are a good choice.
By the way, we have implemented many innovations in the field and have obtained patents for some of our clients.
We will be glad to help you.

Catalyst Handling System
Unfortunately we don't have much experiance about venturi conveyors.
But it is a fact, they just work with light powdery products like hydrated lime...
The system is inefficient because it has to be a fast velocity in the venturi section to suck the product into the conveying line and with the rest of the kinetic energy the product flows in a very dilute ratio through to conveying line.
I think the best is you built a simple plant yourself and then you measure all sorts of velocities and loss of pressure
If you need further information like air consumption then give me the details of your product like dencity, desired mass flow, length of conveying line no. of bends.
In our college in Biel/Bienne, Switzerland we got information how the layout has to be.
Best regards,
Peter Kohler

Literature
Regarding your project I would like to suggest that I am ready to send you a copy of my monograph:
Kurt Leschonski & Andrzej Kmiec, INJECTORS - Principles of Designing and Calculational Methods, Technical University of Wroclaw 1977. This is in English.
There are some examples shown and described in detail for a such installation of pneumatic conveying.
Another available book which may be helpful is:
Wolfgang Siegel, Pneumatische Foerderung, Vogel Buchverlag, Wuerzburg 1991.
Naturally, I am ready to help you in advanced studies to outline in detail such an installation in cooperation with you.
With best regards,
Andrzej Kmiec

Laboratory testing of a Catalyst Handling System
We would like to contact either ar University or an institution in order to carry out some laboratory tests of a catalyst Handling System.
The system consists of an ejection venturi, which is fed with catalyst from a fabricated hopper, and a pneumatic conveying line driven by a roots type blower unit
We would like to build a pilot unit so that we can evaluate the performance.
Our company is located in South West Wales(UK).
Could anybody help us to find the nearest centre? ■
