Hi,
Consider this link: https://www.brooksinstrument.com/en/blog/purging-the-sensing-lines-of-a-differential-pressure-transmitter
Other technologies are better suited for your application, let say Radar.

Hi,
Agree with L.I about design. my experience with resins and rupture disk is to use Jack screw to replace damaged disk.

Hi,
Consider this document to support your work.

Note: Probably good to check with your local EPA and or fire brigade.
Don't forget lightning protection...
Hi,
Better to contact supplier of HX and supplier of heat tracing, who have some experience to share with you. Don't rely on calculation, too many unknowns.
Consider flushing the equipment in case of shut down to mitigate the risks.

Hi,
Do we need to understand that flow rates will be discontinued during operation? leading to stagnation and freeze!
Regarding your brazed plate heat exchanger, the area to add heat is very minimum (side of the plates), better to keep the unit in service (recirculation) and if necessary, add...
Hi,
To add to the discussion.
I'm not familiar with the terminology "conductance"! Q=Delta P*C
Interesting to perform a google search.

Good luck...
Hi,
I will consider the flow as choked flow and isenthalpic to get the temperature of stream at the discharge point to atmosphere.
Having said that:
5 Bars A, the steam temperature is 151.84 C, h = 2748.1 Kj/Kg
At 1 bars A and h= 2741.8 Kj/Kg he corresponding temperature is 135.7 C
Definitely...
Hi,
The first barrier should be insulation to prevent people to get burnt (skin contact or steam leak).
Note: there will be a thermal equilibrium between the steam leak and air.
My 2 cents

Hi,
This is not an incident, it's an accident due to lack of awareness of operator who decided to operate the valve knowing the issue with corrosion. It could have led to more serious consequence. BTW Nobody cares about N2 losses.
The question is why a flexible hose, not hard pipe?
What said...
HI,
Good to read, very nasty chemical. You cannot rely on smell; you need to use calibrated sensor to assess the risks.

Very familiar with this product in soda ash plant.

Hi,
Very obvious, risks identified are Fouling, Erosion, Corrosion. Stagnant pipes are prone to develop bio (bacteria, algae,etc)
BTW you don't want to have your hydrants plugged the day you need to use them. Regular tests to be implemented.
Note: Talk to the insurance broker and Firefighting...
Hi,
Consider using sand filter(s) to remove the suspended solid in your raw water. I've used some of them after pumping river water as a make water on cooling system.
Like Mr 44, mitigate the risk of having accumulation of solid in your network.
Good luck.

Hi,
Probably good to read.
