Abstract:
This invention relates to an universal thermal actuation imbedded in Hybrid High Integrity Pressure Protection System (H-HIPPS) for critical services in pipelines, refiners, power plants and subsea, the hybrid system includes a quick isolation subsystem between an overpressure zone and a normal pressure zone and a quick releasing subsystem between the overpressure zone and a lower pressure zone with quadruple redundancies, more particularly, the universal thermal actuation subsystem based on thermodynamics has a thermal system (pressure sources, volume vessel like air return reservoir and heat source) and a control chamber and shutter valves, the isolation subsystem system controlled by the actuation system has one normal open valve, the releasing subsystem system controlled by the actuation system has one normal closed valve, the actuation systems can be used for both linear and rotary actuation applications anywhere either remote locations or subsea.
