Western Research is now part of AMETEK Process Instruments. They are a combination of the Western Research and AMETEK (formerly DuPont) instruments businesses.
I recommend that you either contact SulphurExperts (www.sulphurexperts.com) or AMETEK Process Instruments (www.westernresearch.com or...
I would be very wary about using any aluminum oxide sensor in a H2 recycle stream. HCl attack, cal drift, temp drift, and the effects of H2 on an oxide will all work against the accuracy of that technology in this application.
The on-line (not portable) quartz crystal technology comes with a...
There are several different technologies being used to measure the sulfur content of low sulfur diesel. I am wondering what your experiences have been with various technologies and techniques.
Are they all adequate or is one preferred?
Are any exceptionally reliable? Unreliable?
I do not know of any appropriate tube, however, UOP has recommended using quartz-crystal (QCM) moisture analysis technology for continuous on-line monitoring in their liscensed processes for many years.
In fact, I believe that technology was originally developed specifically for measuring...
Dear Ponderer,
Your problem is not unique. I know of several possible causes and corresponding solutions to your problem some of which have already been mentioned by our peers. However, a more detailed discussion of your situation would be needed to determine the actual cause and a corresponding...
You should also be aware that mercury will form an amalgam with the porous gold electrode present in some moisture measurement sensors.
The resulting amalgam isolates the sensor's metal-oxide layer from the moisture in the natural gas resulting in a non-responsive sensor. This is particularly...
