Abstract: A small-scale, batch-wise device to simulate high-shear, short-duration emulsification of fluids from various industrial processes at elevated temperatures and pressures for the purpose of determining the quality and stability of those emulsions under different conditions and with different additives. A threaded, transparent tube capable high temperature and pressure is fitted with a threaded bearing with a shaft sealed gas tight at two points with spring-loaded, internally-facing, open rings. A socket head on the external end of the shaft held on a high-speed motor-drive rotates mixing blades on the internal end of the shaft. Process fluids and additives are added to the tube with a vaporizing liquid. The tube is sealed, heated to the process temperature under pressure, then inverted onto the motor drive, by which the blades are rotated at high-speed for a short duration. The tube is righted and the emulsion observed over time at process temperature under pressure.

Abstract: The present disclosure is directed to turbine engines and systems for active stability control of rotating compression systems utilizing an electric machine operatively coupled thereto. In one exemplary aspect, an electric machine operatively coupled with a compression system, e.g., via a shaft system, is controlled to provide shaft damping for instability fluctuations of the pressurized fluid stream within the compression system. Based on control data indicative of a system state of the compression system, a control parameter of the electric machine is adjusted to control or change an output of the shaft system. Adjusting the shaft system output by adjusting one or more control parameters of the electric machine allows the compression system to dampen instability fluctuations of the fluid stream within the compression system. A method for active stability control of a compression system operatively coupled with an electric machine via a shaft system is also provided.
