Abstract: A turbine, including a rotor on a shaft, and having in combination stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on the rotor; internal passages in the rotor producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor; seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages, turbine operations producing shaft power.

Abstract: A separation process, the steps that include: providing an expansion zone, flowing a gaseous fluid into and through the expansion zone, flowing a spray of liquid droplets into the expansion zone to mix with the gaseous fluid and produce nucleation sites, then expanding the flow of mixed gaseous fluid and liquid droplets to cause condensation of gas onto the liquid droplets, and then centrifuging liquid droplets into a separation layer.

Abstract: A method for the recovery of volatile organic components (VOC) released when loading liquid hydrocarbons into a storage or cargo tank, is described. The VOCs issuing from the tank are compressed, and injected into a sidestream taken from the main hydrocarbon stream, which is cooled and used as the absorbing medium, and is conducted to a VOC recovery unit comprising at least a bi-phase rotary separator turbine (BRST). In the BRST the VOC-containing gas is substantially separated into a VOC component and inert gas. The inert gas is vented to the atmosphere. The VOC component or VOC-enriched liquid stream is then returned to the main cargo stream or a cargo tank. Any methane contained in the volatile gases issuing from the cargo tank, instead of being vented to the atmosphere, is recovered or a catalytic process is used to convert methane to carbon dioxide and water for discharge to the atmosphere. The system is particularly intended for the offshore loading of oil into tankers.
