Sulfur Recovery Unit
(OP)
We have 2 of 270Ton/Day Sulfur Recovery Units and S/D,S/U periods are 6/4 days. Re this, if you guys know any up-to-date S/D and S/U procedure to shorten current 6/4 days to 5~4/3~2 days, please let me know.





RE: Sulfur Recovery Unit
One effective method I have heard to shave some time off an SRU shutdown is to do an assisted cool down. Typically you spend quite some time just blowing air through the unit with the blower to cool it down. I've heard of at least one company, BJ Services, that can in some cases greatly accelerate the cool down process by fogging nitrogen and CO2 through the SRU.
