High-acid heavy crude oil
Thread Content
Dear colleagues, the crude oil that our refinery is prepared to process is a heavy crude with a high acid content; the acid value is said to be as high as 3.7. I would like to know what material should be used for the bolts in the atmospheric and vacuum floating-head heat exchangers in order to ensure they can resist corrosion I have some favorites in mind; could everyone who is an ocean lover please recommend some options? Thank you!
I have the latest data on the marine naphthenic crude oil JZ9-3; the evaluation of this crude oil was conducted at the end of December 2010, with a density of 930 kg/m3 and an acid value of 2.41 mgKOH/g.
Oh, any recommendations for high-quality bolts?
Stainless steel 321 material can meet the requirements
Reply to 4# Mountain Bamboo Shoots, thank you! But I heard that the design institute says it’s best for the Mo content to be higher than 2.5! Sorrow...
It seems everyone is considering an upgrade in the material of the equipment, but not deacidification?
