Drying an Internal Floating Roof Tank
Drying an Internal Floating Roof Tank
(OP)
My Friends,
We are commissioning internal pontoon type floating roof tanks for new products. The moisture specification is crucial, typically we shoot for -50F dewpoint in railcars and vessels for these products (1-octene, 1-hexene, etc). We are trying to keep from generating alot of off-spec material.
After hydrotesting (including floating the roof), all the water will be drained. The floors will be squeegeed and the walls hand dried. At this point there is the concern of small amounts of water remaining around the roof seal.
I will gladly take suggestions for the next step. It has variously been suggested to use some heaters and air movers, or N2 to dry further before boxing up and purging with N2.
Any suggestions are appreciated.
best wishes always,
sshep

some desiccant material under the roof with dry Nitrogen blanket might be an answer but may prove very expensive!

Anyway, we have a plan using solid first principles aimed at addressing the problem. I really appreciate the advice.
