"Carbon steel performance under high temp and sulfur gas exposure"
Question:
"What
data is available for the performance of carbon steel at temperatures
of nominally 700F in a trace sulfur gas environment. To compound
the problem, the carbon steel is part of a air-to-air heat exchanger
so the temperature profile would decrease within the exchanger.
Alternately, we would use 316 SS in lieu of carbon steel. Also,
gas phase water would be present. "
Answer:
"Trace" amounts
of sulfur gas needs to be more accurately defined in order to provide
specific materials of construction recommendations regarding the
use of carbon steel as a heat exchanger component. A potential
corrosion mechanism is sulfuric or sulfurous acid corrosion during
downtimes. If sulfurous or sulfuric acid condensation is a possibility,
type 316SS may not be an optimum choice.
