If you feed the hydrogen based on pressure it will automatically flow into the reactor as it is consumed. Use a hydrogen pressure regulator to accomplish this. It is not fancy but effective. You could use a mass flow meter to measure the amount of hydrogen charged if that is something you...
Thankyou for your feedback. I was not expecting there to be a way around having stamped vessels. I feel like it is too large a liability to operate the units at such a high pressure with no stamps. It is too easy for something dumb to go wrong and someone to get hurt. Interesting enough the...
I recently ran into a bunch of Chinese made CO2 extraction equipment. The equipment is not ASME Stamped. There appears to be no other pressure certifications either.
The equipment runs in the 3000 to 5000psig range. The operating temperature is near 140F.
The piping is all less than 1"...
Most People would use bag filters with N2 blow back to push the dried material back into the dryer. If you are getting particles through the bag reduce the pore size on the bags. Work with WL Gore on the bag porosity issue. You may need two stages of bag filters. The second stage may not be...
What about adding a floor drain trench all the way around the building with a sump and a pump. Then pump the liquid to another tank. Possibly outside of the building. You may need backup power for the pump. Or if you could set it up to gravity drain into a double walled undergound tank you...
Greetings all
I have a small stream intermittent stream of water that contains 13 wt% isopropanol. I would like to remove the isopropanol down to about 2% so the flash point is high enough to go to a POTW.
The water stream is generated in 100 gallon batches about 4 times a day.
The water is...

If you are installing new piping systems in the facility, use the current code requirements.
If you are modifying an existing system AND you are not having problems with the piping designed to the old code, continue using that code to validate the piping changes.
If your having...
Change one of your injection pumps to the bottom outlet of the reactor. Make one of the top nozzles your outlet. Put a short tip tube down into the reactor. That will set the level in the CSTR. How are you keeping it at 6 bar. Back pressure regulator on the outlet flow? Are you adding a...
Your hydraulic system probably has a positive displacement pump, With some slipage. Maybe you could just count revolutions to get close to your flowrate, in stead of the meter.
If you are making the calculation yourself, I would think that solar loading is the factor that controls the amount of evaporation occurring when the tank is just sitting there with no flow in or out.
I would also look to the epa information to get a solid start on this.

I would bet if you talk to Zeeco, the allowable load from piping is zero. Piping must be self supporting and must have an anchor point within 20 ft of the nozzle so absorb piping loads. Just my guess, I worked a short time for one of their competitors. I will end this by saying I am not an...
I think the first question is. Have they actually produced this material, at this specification in the lab? If the answer is yes then how?
That will give you some insight as to what to do. Then it is just a mater of scaleup. I think that is a better approach then just guessing that a...

When you stir pure hexane static builds up to very high voltages. So when it finally discharges it arcs through the glass at a weak point. The arcing will blow a chunk of glass off about the size of a nickel. Sometimes the glass will fall off immediately and sometimes there is a...
At least your smart enough to know that you don't know. That is a HUGE mark of intelligence, but you should sub this out to an experienced company and try to learn from them.

Sometimes the glass lining process is not 100% perfect. The reactor probably failed spark testing in that location so the factory added the tantalum patch to solve the problem.
I have asked about adding tantalum diptubes to help with static dissipation as we mix straight Hexane in some of our...
