Where is it?

1: can you put the thermowell in an elbow and use the inline pipe for the thermowell? Check your standards or Google elbow thermowell standards. 2: do you mean nozzle extension from vessel wall? 8” (200 mm) is very common, but I’ve seen “as short as possible” up to 12”. I’ve never seen 1800 mm.

Talk to BS&B. Good Luck, Latexman

Back in my old phenolic resin days, after the operator opened the vent and cracked the man way open < 1 inch they would put a slight vacuum drag (negative pressure) on the still before opening the man way wide open. Man ways had cross bars so no one could fall in. That was 40 years ago...

IMO, that is not a serious question. Good Luck, Latexman

sts098? Good Luck, Latexman

Addition systems can be engineered and built so the manways can be closed permanently, or until maintenance turnarounds occur. Decades ago, I saw the same thing where I worked. It's a management problem. Management has to decide whether exposing people is okay or not. There will be a lot of...

No. Can you be specific? Good Luck, Latexman

Rearrange the equation for m/sec = . . . and then solve. Good Luck, Latexman

m/sec is not a variable. It’s the units of mass flow rate (m). Snickster gave you the definitions. Please read them: m is mass in pounds (weight mass W not W/g mass) m/sec is mass flow in pounds per second MW is the molecular weight of gas which is S.G. times 29 (MW for air) Z = 1 for NG...

Besides the equipment, it also depends heavily on the process (components, concentrations, temperature, pressure, etc.) and operation inside the equipment. Not enough detail. Good Luck, Latexman

TiCl4, About 30 years ago, I asked my megacorp's fluid flow expert the same question, "What is the effective shear rate in a centrifugal pump?". He told me to use: Shear rate (sec-1) = 10 x RPM/60 or 10 x RPS. This equation has worked well for me ever since. There was also a lot of...

I’d say no. Pure water has no electrical conductivity. EG has low electrical conductivity. You will be at the mercy of the level of ions in your system. I think if it did work, it’d be a PITA with a lot of false indications. Good Luck, Latexman

A meaningful Subject that can be searched is required. Report to Admin and have them modify the subject to your choice. Good Luck, Latexman

You need the pipe specs from the original project that installed the piping. Or, call in your mechanical integrity folks and start measuring! Good Luck, Latexman

TiCl4, OP is not handling a flammable. It is combustible; handled below the flash point. Definitions are critical to properly analyze the reaction so of a operation. Good Luck, Latexman

My guess is butyl acrylate. Good Luck, Latexman

No, no one does. "No specific time lines given". Good Luck, Latexman

The pressure transmitter reading the upstream pressure could be wrong, and both POSRV’s popped correctly? Good Luck, Latexman

Any source of pressure dynamics/surges nearby, like a pump or valve? Good Luck, Latexman
