Superheated-steam drying loop with MVR heat recovery
A wet cake is dried in a superheated-steam dryer (steam as the drying medium instead of hot air), and the evaporated moisture — pure steam — is recovered by mechanical vapor recompression (MVR) plus a trim superheater into high-grade superheated steam that reheats the recirculating drying medium. Superheated-steam drying is the energy-efficient route for biofuel and food solids (distillers' grains, beet pulp, lignite): because the drying atmosphere is steam, the evaporated water leaves as more steam whose latent heat is recompressed and reused, instead of being lost in a humid exhaust.

View & openBio-ethanol: energy-integrated distillation + MVR stillage concentration
A dilute beer (10% ethanol) is concentrated toward the azeotrope in a beer column, and the water-rich stillage bottoms are concentrated in an evaporator whose vapor is recompressed by a mechanical-vapor-recompression (MVR) compressor — recovering the stillage vapor's latent heat as high-grade heating duty instead of venting it, the energy-integration route that eliminates a separate thermal oxidizer.
