摘要： A steam turbine plant has a steam turbine and an inlet steam collection line with an inlet steam collection line segment is provided. The inlet steam collection line supplies a steam consumer and is introduced into outlet steam flow of the steam turbine at an inlet steam introduction point of the inlet steam collection line segment. A supply steam device has a switching armature for connecting the supply steam device to the inlet steam collection line segment upstream of the inlet steam introduction point. The armature is triggered and switched such that if outlet steam pressure in the inlet steam collection line segment is lower than target pressure, the inlet steam collection line segment is connected to the supply steam device for conducting steam and disconnected between the armature and the inlet steam introduction point, otherwise the supply steam device is separated from the inlet steam collection line segment.

摘要： The integration of a petroleum refinery, or a petrochemical complex, with an off-site power facility in which the latter provides a vaporizable coolant for vaporization in the former. Vaporization is effected through indirect contact with one or more waste heat streams; the resulting vapors are expanded through a turbine, to a lower pressure, from the resulting motion of which power is generated. In most instances, the process generates more power than its connected load. Preferably, the coolant is indirectly contacted, at elevated pressure, with a plurality of refinery process streams in series and in the order of increasing temperature. Resulting vaporized coolant phases are passed through individual turbines, or through different stages of a multiple-stage turbine.
