corrosion prevention of non used equipments
(OP)
I would like to know how to prevent internal parts of equipments which are not in service for a long time from corrosion.In our plant some of equipments ( towers and coolers )are in two set and in pararel so at a time only one of them is in service and the other will be out of service for a long time ( more than two years).We have faced with severe internal corrosion which lead us to extra works and cost ( retubing ,...).We think to use nitrogen blanket but for some reasons it was not successfull.Any comments would be appreciated

Other than that Munters makes a dehumidifier that is used to keep large pieces of equipment such as boilers and turbines dry while out of service.

The boiler was flash drained to remove condensate from undrainable tube circuits, followed by a nitrogen blanket.
Dehumidification was used to keep the boiler firebox dry (the exit flue gas ductwork was sealed with heavy plastic tarps to avoid the ingress of moisture).
