Within a chemical processing environment I have an afterburner which is supplied with unwanted bi-product substances from a scrubber and, rather predictably, the afterburner depletes them.
HOWEVER, due to a carbon reduction initiative my wise superiors want, the afterburner is to be regularly turned off (for as long as 4 months in the summer months) which unfortunately allows the contents to change phase to a liquid due to the temperature drop and gives rise to significant amounts of caustic which seeps from flanges (which have thermal fibrous gaskets – good for temperature, bad for sealing caustic) and so I have caustic dripping & building up all over the place from an afterburner a couple of hundred feet from the ground.
I do have a fabricated duct to fit and stop leakage from the main body of the afterburner, but this is only stopping the seepage from one place & the flanges will still leak, this also won’t stop the caustic building up in the main chamber.
My question is:-
1. What sealant should I use between the flanges to stop the seepage of caustic and,
2. What addition can I add to the new ducting (or somewhere else) to generate a catchment area which I can siphon off the excess caustic at regular increments and direct back to the scrubber to recycle the caustic when the darn thing is allowed to run.
I will need to bring a contractor in to do this due to our skeleton staff, and wish to also know who would be best to address this in the UK.
ALL HELP IS APPRICIATED MY ENGINEERING BROTHERS & SISTERS, THANK YOU.
