51316-7170-Effect of Temperature on the Crevice Corrosion Resistance of Austenitic Stainless Steels

Product Number: 51316-7170-SG

ISBN: 7170 2016 CP

Author: Martin Rodriguez

Publication Date: 2016

$20.00

Resistance of S30400 and S31600 SSs to chloride-induced crevice corrosion was assessed in a wide range of temperatures and chloride concentrations. Repassivation potential of S30400 SS decreased with increasing chloride & temperatures from 0 to 60ºC, and it a constant value in the range from 60 to 90ºC regardless of chloride.

Failure Analysis of High Temperature Plate Heat Exchangers in Converter Section of Sulfuric Acid Regeneration [SAR] Unit

Product Number: 51323-19420-SG

Author: Sudharsanan Soundararajan

Publication Date: 2023

$20.00

A Sulfuric Acid Alkylation [SAA] unit in a refinery converts olefins and butane to high octane alkylate using highly concentrated sulfuric acid as a catalyst. The function of this Sulfuric Acid Regeneration [SAR] unit is to regenerate spent sulfuric acid from alkylation process into clean sulfuric acid of 99.2% concentration, which is then recycled back into the SAA unit. The process of SAR can be classified in to following four steps:

• Formation of SO2 by the decomposition of Spent acid and combustion of H2S.
• Cooling and Purification of the SO2
• Conversion of SO2 to SO3
• Absorption of SO2 in H2SO4
