Which would be a better way to mothball a reactor jacket service made of carbon steel to minimize corrosion? The heat transfer fluid is glycol-water mixture (~50%). Drain out the glycol and fill with nitrogen or clean out the glycol with water, followed by draining and blow dry with compressed air (
Have an insight or suggestion?

Re: What is the best way to mothball a reactor jacket service?20 February 2012 at 1:29pmThe answer depends, in part, on how long the reactor will be mothballed. For answers to these types of question, I refer to MTI Publication 34 - Guidelines for the Mothballing of Process Plants written by Ronald Twigg. For jacketed reactors, the general recommendation for reactors is to: 1) Drain all jackets and blow with dry air or nitrogen. 2) Fill the jacket with inhibited antifreeze to the strength required for expected ambient temperatures. Vessels inside heated buildings require no antifreeze and the jacket is left open after draining and drying. For more information and additional details, consider obtaining a copy of this MTI publication.
