Refinery shut down
Refinery shut down
(OP)
Hi,
We have small refinery called Topping Plant we only produce Diesel from it in Our Field. I Have one concern about temporary shut down from this plant for only ( 1 to 2 months) not for maintenance only due to security situation.
My question here any procedure will be applied when such shutdown for this plant ( procedure for Suspended the plant).
Thanks

Corrosion concern Sir
RE: Refinery shut down
This means - isolate, drain, vent, purge and inertize all vessels, rotating equipment and piping, and maintain it under slight positive pressure. Ideally use Nitrogen because it is not flammable. In normal circumstances one could also use dry fuel gas, but since you are facing potential security problems it is the best if you keep your systems free of anything that can burn or explode. I'm thinking that even leaving the entire plant exposed to atmospheric air (after purging) is a better option than filling it with fuel gas. No real damage should happen within 1-2 months if equipment is open to ambient air.
Non-hazardous and non-corrosive systems (i.e. Instrument Air, N2, fire water etc.) can be left as-is, meaning no draining and purging will be required.
If for any reason there are chances for this shutdown to last for 6 months or more, you should be looking at mothballing of the entire plant. This is much more complex thing and it requires inert fluids, greasing chemicals, coating agents, rust prevention chemicals etc.).

in the circulating case I have used only Anti-foulant, so I am in the correct a way ??
Note that the injection location of Anti-foulant at crude feed pump and filming amine at over head tower
Thank you
