Have you ever heard of steam-vapor recompression to recover vent steam and recompress back to usable low-pressure level? Is it really practical to do so? And what type of compressor (or ejector) is suitable for the steam recompression?
Have an insight or suggestion?

Re: Have you ever heard of steam-vapor recompression to recover vent steam?17 March 2009 at 1:29pmIt is very much possible to recompress the vented low-pressure steam to a usable level medium-pressure steam using some high-pressure steam. Generally, a thermo-compressor (steam ejector) is designed to suit the steam system conditions where it is going to be installed. Thermo-compressor systems are already installed and working at several process industries. Paper machines are the most common application for thermo-compressor systems.
While a mechanical recompression system is also possible, we have rarely seen mechanical recompressors in steam service.
Also before proceeding to a thermo-compressor, we have to exhaust all the practical options of low-pressure steam utilization.
