It is a polymer production plant. It is not looped, and would be impractical to do so. There are some small <50 gallon reciever near some users, but the largest one does not have any. There are big swings during a certain process in which a large amount of air is used for about 1-2 seconds at...
Afternoon all,
We currently have three air compressors at our plant. A 100HP (load-unload), 60HP (modulation), and a 50HP (modulation) - the 50HP is rarely used due to it's age. I had an air survey conducted to evaluate the system for possible improvements. I found that the flow is less than...
Hello everyone,

Hello All,
I am currently working on a proposal to replace the plant compressors. The plant currently has one 100hp load-unload compressor and one 60hp inlet modulation compressor. The idea was to replace both of the compressors with a single large VS compressor. However during a recent air...

I am guessing that a blender would...
I am currently evaluating adding a small ribbon blender to be used in our compounding area to mix additives. This is small semi-portable ribbon blender that is only 15 cubic feet in volume. I am trying to determine if it needs to be under a nitrogen purge to avoid a possible dust explosion...
