Diagramm For Dilute And Dense Phase Pneumatic Conveyor Systems
Hi there,
I am not really an expert on pneumatic conveying. The only thing I have to offer is a diagram that shows the areas of dilute and dense phase conveying as well as the transition area in a universal way. The diagram reflects published data sets of industrial installations using key parameters of the turbulent flow in pipelines.
Estimation of pneumatic conveying systems from this point of view is one of several parts of the free ViSUAL BASIC software Fluidi2000, that can be downloaded from the following link:
https://skydrive.live.com/redir.aspx...s60rZ0M*8fA%24
The language is German. Nonetheless using the program should be easy. It runs even under Windows 7 (32 bit).
The whole theoretical backgrund is published in Germany as an ebook:
http://www.epubli.de/shop/autor/Manfred-Heyde/3168
Best regards
ManfredH
Postscript 1
The programm seems to allow calculations at higher gas temperatures than 20 deg C, but I never found publications offering data sets of high temperature conveing to verify such calculation results.
Postscript 2

Reducing Dust
Dear Reader,
I am operating a lean phase pneumatic conveying system that transports around 45tph polyethylene pellets at around 33m/s.
I wish to reduce this velocity to as low as possible. My info is that saltation occurs at around 23m/s.
Any advice?
Dave. ■

Re: Design Calculations For Pneumatic Conveying
Dear Dave,
Without more information, you cannot expect any advice.
For an estimate calculation, at least the material properties need to be known (particle size, particle density, bulk density) and the installation data (horizontal length, vertical length, number of bends, pipe diameter(s), altitude of operation, type of feeder, type of receiver and ambient data s.a. temperature and RH.)
Have a nice day

Re: Design Calculations For Pneumatic Conveying
Dave, based on my test data, saltation velocity for PE in a 4 inch dia pipeline and a solids to air ratio of about 5 is 15 meters/sec. For your 45 tons/hr conveying rate line diameter is probably 10 or 12 inch. For a 10 inch dia line, saltation velocity will be = 15 x (10/4)**0.5 = 23.7 meters/sec.. Looks like your 23 meters/sec is about right.

Saltation Velocity For Pe Pellets
Dave,
Saltation velocity for pelleted polyethylene in a 4 inch diameter pipeline is about 15 meters/sec. This number is based on actual operating data. Saltation velocity increases with increase in pipe diameter. For your 45 tons/hr conveying rate, your line size is probably 10 inch at pick-up point. For a 10 inch line, saltation velocity should be = 15 * (10/4)**0.5 = 23.7 meters/sec. Your 33 meters/sec velocity is about 20 % higher than the saltation velocity.
If reducing fines and dust is the main reason for reducing the velocity, even a 20% reduction in velocity will not materially reduce fines. You will still need fine removal equipment.

Mr. Agarwal,

Thanks very much. ■
Assistance Provided By Agarwal Article
It's a pleasure to see a practical article this well laid out. I found that the sample worksheets detailed in the appendices are well suited for implementation as spreadsheets for standardized calculations of this sort. Without going into great theoretical details, this provides a workable procedure for sizing pneumatic lines, obtaining gas flows, and so forth in a format that's friendly for junior engineers as well as more experienced individuals.
Upon review, I have a couple of suggestions:
• The note after equation 2 should be re-worded (in my view) to say something like " 'L' is the equivalent length of the pipeline in question; that is, the sum of the actual length of all straight runs plus the equivalent lengths of all bends, diverter valves, flexible hoses, and the like."
• I'd suggest adding in a table or some sort of decision tree in section 2.4 that would assist in making a selection of the value of the slip factor. The author notes that "coarse or hard solids" use a slip factor of ~0.8, while "fine powders" warrant a slip factor of ~0.9. One or more rules of thumb to help the user determine whether the slip factor should be 0.8, 0.9, or some other value altogether would be handy.
• A very minor note: many authors in fluid mechanics have noted that the Fanning friction factor is less used these days than the Darcy version (no idea why, but this is what I've seen). Some note in section 2.1 in the area of equation 7 about interconversion between the Fanning and Darcy factors couldn't hurt.
I say these since I'm trying to put myself in the shoes of a first-time user, or an editor of a more general chemical engineering publication: from my own publication experience, those are questions I could see coming up. ■
