  • Compressor driven by ORC waste heat recovery unit and control method
    Patent number: 10975733
    Abstract: A power converting system is described, comprising a source of waste heat and an organic Rankine cycle system. The organic Rankine cycle system in turn comprises at least a turboexpander, at least a rotating load mechanically coupled to the turboexpander and driven thereby, and a variable-speed mechanical coupling between the turboexpander and the rotating load.

  • CONTROL SYSTEM FOR A COMPRESSOR WITH SPEED-BASED SUBSYSTEM, SYNTHESIS PLANT AND CONTROL METHOD
    Publication number: 20190078575
    Abstract: Control system arranged for a rotary compressor driven by a rotary engine, and includes: a first control subsystem, a second control subsystem and a selector; the first control subsystem is arranged to provide a first control signal as a function of the performance of the compressor; the second control subsystem is arranged to provide a second control signal as a function of the speed of the compressor; the selector is arranged to select the first control signal or the second control signal as a third control signal to be provided to a power control input of the engine.
