I would like to ask that hero: What is the reason for the failure of light naphtha corrosion in the hydrocracking unit and how to adjust it? This post was last edited by DAC Junlintianxia on 2007-12-6 20:54 ]
Check whether there is organic sulfur or inorganic sulfur in the naphtha. If it is inorganic sulfur, it means there is a trace amount of water dissolved in the oil, and water has a strong ability to dissolve hydrogen sulfide, causing corrosion failure.； If this is the case, the settling time can be increased, and the situation of dissolving the dissolved water will be better. If the organic sulfur is present, it may be the deactivation of the refined catalyst loaded in the lower part of the cracking reactor, then there is no other way but to replace the catalyst.
Thank you, the poster above, we will often learn from each other in the future* Got it
