<p>There is disclosed a method of operating a steam compression apparatus 10 comprising a compressor 12 and a drive unit 14, the method comprising: operating the drive unit 14 to drive the compressor 12 so as to provide a superheated steam flow; cooling the drive unit 14 with a liquid cooling medium, so that the cooling medium recovers thermal energy from the drive unit 14; and de-superheating the steam flow from the compressor by injecting the cooling medium into the steam flow downstream of the drive unit. An alternative method of operating a steam compression apparatus is also disclosed in which the steam flow from the compressor is de-superheated by indirect heat transfer between the steam flow and the cooling medium downstream of the drive unit 14, thereby vaporising a portion of the cooling medium to provide a vaporised flow which combines with the steam flow. Corresponding steam compression apparatus 10 is disclosed comprising a compressor 12, drive unit 14 and de-superheater 16, 16'.</p> |
