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.

There is provided an apparatus (30) and method for conditioning the flow of a mixed phase flow from a supply pipe (101) from a hydrocarbon well. The apparatus (30) comprises an elongate reservoir (11) having a first end for receiving a multi-phase fluid flow from the supply pipe and a second closed end, there being provided a gas outlet (02) from the upper part of the first end, a liquid separation region downstream of the first end, and a liquid outlet (12) from the lower part of the liquid separation region; and a gas-liquid mixer to which the gas and liquid outlets are connected such that the separated gas and liquid may be recombined. The reservoir (11) may accommodate surges of liquid such that the flow rate from the liquid outlet is relatively invariant over time compared to that of the flow received by the apparatus.

A liquid transfer apparatus comprises an output terminal device, a receiving terminal device, a connecting pipeline, and a control device. The output terminal device includes a first pressurizing member for filling the first storage container with high-pressure air. The receiving terminal device includes an air pressure adjusting member for adjusting the air pressure inside the second storage container. When the liquid transfer apparatus is in a non-transferring state, the air pressure inside the second storage container is high enough to prevent the liquid in the first storage container flow into the connecting pipeline. And when the liquid transfer apparatus is in a transferring state, the pressure difference between the inside of the first storage container and the inside of the second storage container is sufficient to drive the liquid in the first storage container to enter the second storage container.

Embodiments provide a surge suppression device, a surge suppression system, and methods for operating the same. The surge suppression device includes a valve body and a plug. The plug is rotatably positioned in a hollow space of the valve body. The plug includes two surge suppression openings defining a fluid flow directed to surge suppression. Each of the two surge suppression openings includes a circular plate having a plurality of orifices. The plurality of orifices allows reduction of surge pressure when the water passes the first fluid flow path. The circular plate has a concave or convex geometry.

Methods and systems for controlling pressure washer devices are provided. Pressure washers comprising at least one control unit and the ability to regulate functions of at least an engine of a pressure washer are disclosed. A control unit receives inputs from a user or various sensors provided in communication with the control unit, and is further capable of outputting a signal based on the inputs, the output signal operative to maintain or control the operating functions of an engine, pump, or motor.
