The process of oil extraction can be enhanced by dehulling, produced from groundnut seeds serve as a good source protein, vitamin, fat, oil, and crude fibers. A dehulling machine was developed, having two rollers, rubber beaters, screen, blower unit, seed chaff outlet. separator unit has centrifugal blower, screen collecting tray. It’s powered 3 hp electric motor, which transmits constant speed...

Abstract Radial compressors, Blowers, which are often used in modern devices for medical ventilation, known to have non-linear dynamics regarding the generated pressure. To make them accessible large field of linear control theory their model needs be linearized. This paper uses a gray box blower driven by brushless direct current (BLDC) motor design controller based on feedback linearization. ...

The AE&C single absorption–scrubbing process has long been an alternate to double absorption for the production of sulfuric acid. In recent years regulatory pressure to reduce SO2 emissions from sulfuric acid plants to 1.0-1.25 pounds of SO2 per ton of acid produced (to about 120 PPM) or less coupled with the increased value of energy has enhanced the desirability of the single absorption–scrub...
