It is not my chemical project, steam is stated as the mean to sterilize.
I was ask to furnish the sterile air supply , and the avoinding the pressure to be below the limit stated, fall on my hea. and I guess such method , but I can not show it by any formula ,or procedure.
The bioreactor will...
In a bio reactor I need to steam heating up to 1 barg to sterilize it.
First I will allow the steam to flow trough all openings , then close all it , and let the steam to build up at 1barg for 15 minutes.
After it I will shut off the steam.
Here it cames my concern, how quick will the...

I have this facts.
To supply air at 2m3/min at 1.5 bar abs to a fermentation vessel.
Air shall be filtered to 99.99 % particulate < 0.2 micron.
Air supply could be
1.-
A roots type blower at 1.5 bar absolute
2._
A screw or piston compressor rated at 8 bar absolute.
Cons for roots type
I can...
I would fit a tee at the pipe top part at the start of it just after the pod valve , and a branch to be higher than the liquid level of the pod , so the air will not enter from the down tank, it will take from the atmosphere, and mean while the pod is empty the vacuum release valves will allow...
By the costumer requirement I have to supply 2 m3 /min at 0.5 bar,or 70CFM at 7 PSIG .
Of course the best option to it is a ROOTS type blower.
But I want the source to be a 7 bar or 100 PSIG commpresor , just because I need to filter and dry the air to be esteril, and I can not get filters...
From Wikipedia
The slug is an English unit of mass. It is a mass that accelerates by 1 ft/s² when a force of one pound-force (lbf) is exerted on it. Therefore a slug has a mass of about 32.17405 pound-mass or 14.5939 kg.
1 slug = 1 lbf·s²/ft
The slug is part of a subset of coherent units...
I know that on ships, the HVAC run in a HIGH PRESSURE air syitem , just to get small duct size .
My question is what kind of filter media and shape is used , and what is the standard pressure rated.
