Single-pass tangential flow filtration (SPTFF) is used in biopharmaceutical manufacturing to reduce volumes and concentrate products. The staging of multiple membrane cassettes makes it possible achieve high concentration factors one pass, but at the same time increases system’s complexity. This work aims provide comprehensive understanding SPTFF both cassette level equipment by evaluating impa...

Abstract In this study, a strong anionic resin was used to remove the chloride ion in diethanolamine of sweetening unit gas refinery. A laboratory pilot has been investigated as resin-filled bed evaluate reaction temperature, concentration, saturation, recovery rate, optimal flow hydrogen strength and performance work. The saturation time, capacity resin, temperature changes concentration outpu...

The paper reports on photoelectrical performance of the mid-wave infrared (MWIR) (111) HgCdTe high operating temperature (HOT) detector for the fast response conditions. Detector structure was simulated with software APSYS by Crosslight Inc. The detailed analysis of the time response as a function of device architecture and applied bias is performed pointing out optimal working conditions.

Power Control Centers need to model their systems in real-time to support the necessary control and security functions. Neighboring independent system operators and regional transmission organizations also need to exchange system data. In the USA, a data exchange structure based on EPRI’s common information model and XML is evolving. Currently, this data exchange is implemented by providing eac...

The potential benefits of optimal service scheduling for cleaning heat exchangers based on minimizing operating costs are explored. A demonstration is performed on a simulated 20 ton air-to-air vapor compression air conditioner. The costs of regular service schedules (indicative of current practice), minimal schedules needed to maintain comfort, and the optimal schedules are compared. Generally...
