Greenish sulphur in SRU

Greenish sulphur in SRU

Greenish sulphur in SRU

(OP)
S!
In a sulphur recovery unit was found greenish sulphur in one of the seal legs.
The SRU process acid gas from a Sour Water Stripper and a Amine Unit.
There are suspicion of ammonia contamination from SWS or even DEA from Amine unit.
Anyone faced similar problem?

RE: Greenish sulphur in SRU

We usually made green sulphur on St. Patrick's day. You are corroding out your unit. The green is copper sulphate.

RE: Greenish sulphur in SRU

owg:

So, would the "copper" be from the trace chemistry in the other metals and would it be enough to produce this byproduct in visible quantities?  Otherwise, I would ask where the copper (yellow metal) would (should?) be present in an SRU, or where it's coming from.

Regards,

SNORGY.

RE: Greenish sulphur in SRU

I think the copper sulfate came from the metallurgy somewhere upstream. Also note that mixing blue and yellow --> green.
