Refinery propane failing the copper strip test
Refinery propane failing the copper strip test
(OP)
We have had problems with our propane failing the copper strip corrosion test. We recently started more frequent testing of our propane. We have also recently switched KOH manufacturers. We don't routinely test upstream of the KOH treater, but anytime that we have--the results turned out good. Downstream of the KOH treater can be all over the map. Another thing that we noticed is very little water formation in the KOH treater. The new KOH does have ~50 PPM sulfates, where our old KOH didn't list any on the COA. Has anyone had any similar experience?

An Examination of Interfering Factors in the
ASTM D-1838 Copper Strip Test
is available from gpaglobal.org
it has a matrix of what different contaminates cause what kind of strips.
You can have dry propane going into the beds, but you still need to add water to th KOH beds otherwise, the beads coat up and there is no active KOH area.
