hydrogen sulfide corrosion Chloride-ion stress-corrosion

You're looking at an answer to...

Hydrogen/hyd rogen sulfide corrosion Chloride-ion stress--corrosion cracking These are two of the problems that Standard of Ohio had to design around when they built the first large commer­ cial ISOCRACKER unit in the United States. The unit processes marginal feedstocks that are not effectively con­ verted to gasoline by catalytic cracking. Sounds like trouble, doesn't it? But it wasn't. Standard of Ohio's engineers specified INCOLOY* alloy 800 for the

first stage furnace and the heat ex­ changer (shown above) used to preheat the feed...because of the alloy's high resistance to hydrogen/hydrogen sul­ fide corrosion; resistance to chlorideion stress-corrosion cracking...and its strength at elevated temperatures. That's how Standard Oil did it. Plants all over the country, in the chemical processing and petroleum refining in­
