Increasing pressure of saturated steam
Increasing pressure of saturated steam
(OP)
Hello
I am wondering if it is possible to go from saturated steam at say 5MPa(a) @ 80% quality and compress it to a pressure of >8 MPa(a) and the same quality.
Would this be a simple case of reciprocating machinery pressurizing the steam or would it involve other mechanisms.
Thanks,

Do you have a new, longer distance that your system must supply steam ?
Generation of saturated steam is all about moving heat from one place (the boiler) to another (some type of HX or humidification unit)
The pressure requirement of a saturated steam piping system is controlled by the distance you are required to "move the steam" to get to your destination. A price is paid if the distance is long as the steam will drop in pressure.
If you need saturated steam at a higher pressure, increase the pressure at the feedwater pump. If the boiler is undersized for the pressure....get a new boiler !!
If you find a "steam comressor" on the market..... please tell us about it
My opinions only

If steam has a dryness of 80% at 5 MPa(g) then its temperature is 265.23 °C. In order to increase steam pressure to 8 MPa(g) keeping dryness at 80%, temperature must be raised to 295.92 °C.

Had this been a traditional use of the boiler i would've just gotten a new boiler but im trying to do a broad level parameter design of a process loop which is limited by the amount of energy available and the amount of steam required. Additionally i have multiple cascading loops which make the process a little more complicated.
But thank you for the replies
