I'm curious about anyone who has experience with LARGE tumbling operations.
We have a large volume (perhaps up to several tons a day) of oblong ceramic balls ~1.5 cm diameter that we would like to make more round, preferably marble roundness. surface finish is not important as long as it isn't...
I'm looking into parallel mono-tube boilers for producing 15 psig steam from concentrated sunlight. (I guess parallel makes it not so much a "mono" tube, maybe water tube is more accurate). Looking into using aluminum pipe.
I would want to use compression fittings, but generally they are not...
I am researching methods for coating oddly shaped agricultural seeds with a hard spherical coating. A simple building up of layers of films will not make a long thin seed round, except perhaps with an excessively thick shell. Other methods involve isolating individual seeds and delivering them...
A test apparatus contains saturated methanol gas being condensed. I'd like to have a pressure gauge tell the pressure of the gas. I have found gauges rated for R-14a, ammonia and other common refrigerants, but nothing explicitly for methanol.
Is there a way to tell if a gauge is fit for use...
In a medium scale process using liquid co2 as a solvent, we wish to recycle nearly pure co2 gas to 800 psi liquid. co2 gas is above atmospheric pressure and below 20 psia. about 400 lbs (200 kg) of co2 to capture per day.
Because co2 stream to be captured is from a tank in the first place, i...
I have a co2 gas stream to be captured and stored. 400 psi and below room temp. Water must be removed first. We are thinking 1/4" stainless into a filter with an adsorbant into 1/4" carbon steel pipe. Any suggestions about filter manufacturers or filtration strategies?
so many good ideas...
We have a carbon steel vessel that will contain a food grade process. Also, there is significant acidity that would corrode the steel. Enameling sounds like a finiky process, though we are considering it. electro and electroless nickel plating sound potentially useful.
the vessel is several...

Hi
I'm developing an apparatus for high pressure processes. It will be employed for both experimentation by a private non-accredited educational institution and also for...
There are enamel cooking pots, water heaters and iron bathtubs. I'm wondering if anyone knows about enameling a carbon steel vessel that will be used in a "food grade" operation. (stainless is just too expensive)
The temperature will not be much, that of boiling water at most, so the enamel...
Hi:
I chose the pharmaceutical forum because I am wanting to coat a carbon steel reactor vessel with a pharmaceutical grade lining. Enamel is an obvious solution. One thread here (thread116-73024) states that thermal expansion from room temp to 100C will cause the coating to flake. I do not...
I thought i posted this already but an hour later it isn't in the forums. Must have pushed the wrong button or something.
We've got a 6" port that needs sealing on a 1500 psi, under 100 C vessel full of super critical carbon dioxide and dissolved oils, terpenes, ethanol and others. A grooved...
hello:
I am designing a pressure vessel and have questions about how to seal the lid, which will be opened and closed frequently.
The vessel will be containing supercritical carbon dioxide and whatever organic substance may be dissolved in it (oils, ethanol) at a pressure of 1500 PSI and a...
