Using steam as an inert gas blanket?
Using steam as an inert gas blanket?
(OP)
Can steam be considered as an inert gas for blanketing?
In a project I am considering blowing a slurry along a pipe using nitrogen, but given that we have more avaliblity of "cheaper" steam that would be a better option.

Nitrogen could be used, but given that even wet steam will not effect this material, steam would be in preffereance to compressed air.

I think you ought to rethink on how you phrased your question. Or are we missing something?
RE: Using steam as an inert gas blanket?
The material to be trasfered (blown) is still base residues, can be warm (upto 50 deg C), normal would be open to atms at this stage, all zoned area - so all current precations taken.
So interms of inert blanketing - that is not what I am wanting.
But interms of not using a "gas" that will not become an explosive medium, I require.

No chemical reaction will take place.
Will be cheaper than Nitrogen. + a bit of warmth will lower viscosity.

Are you blowing this material into a large container with a low pressure/vacuum rating ?
If so, consider the vacuum generated when the steam condenses and water collects at the bottom of the container.
These may be affects that are undesireable and would not be present with a nitrogen based system

The line will be running at 5m above ground, so plenty of saftey margine if it did go. Planning on using either shed 40 mild or dn 150 ss.
Thanks for all your reply, so looks like steam will be a good option.

Also, as MJCronin says, take into account vacuum created when steam condenses. Equipment that is steamed out should be designed for full vacuum, or other safeguards used.
