Packaged air cleaning systems tame desert dust storms in Oman
Vast storms created when cold, northwesterly air masses slam into hot, southwesterly monsoons, moving lethargically over the Sudan and Red Sea, generate swift downdrafts that strike the ground and deflect forward in a powerful, swirling air stream up to 500 km long. As the wind moves along the ground, it churns up particles ranging in size from 80 to 2000 micrometers. This churning also kicks up particles in the 0.1 to 80 micrometer range, and these may rise to heights of 500 m or more, the smaller of which remain suspended for hours. These conditions made it imperative to protect the blades and internal mechanisms of the gas turbines in use at Yibal, Sultanate of Oman. Each of the gas turbines is equipped with a packaged intake air cleaning system. Because no single air filter has been designed to handle effectively the extremely high concentrations of particulates encountered during storms, the AAF air filters are multistage filtration systems. These systems are discussed.
