dear achi81
you can do this in two scenarios:
1- use regular chock valve with de-superheater (spray attemprator) to control the steam temperature, this option is cheap and simple.
2- use turbo-expander, then you will not need attemprator and this option will be expensive and only needed when you ned to utilize the power from steam to re-compress another process stream.
