Did anybody have experience with corrosion on the upper trays in main column on CDU, made of Monel (alloy 400). Any experience with other alloys resistant to HCl and H2SO4 corrosion but also ammonia/amine attac also.
Any experience about neutraliser, filmer dosage and wash water incection into the O/H line of mail fractionator on FCC Unit. Is it allowed to mix neutraliser anf filmer into the washwater line? What is common practice for injection of neutralizer,filmer and washwater and why?
Any experiences regarding mercury contaminated crude oil processing from corrosion point of view?
Is there any mercury limit in crude to avoid overhead fractionator trays (made of Alloy 400) LME corrosion by mercury?
What is the best metalurgy solution for HCl overhead corosion and mercury...
Can anyone define the wash water quality for air cooler washing (FCC unit)if the cooler tubes are made of CS A210A-1,temp is 113 C, preassure is 8,8 bar? Which are relevant lab parameters to monitor and their limits? The aim is to remove corrosive salts of ammonia bisulfide/ammonia chloride...
