Drying of Slurries in Spray Dryers - BGU

Drying of Slurries in Spray Dryers - BGU

A typical spray drying chamber consists of an atomizer, transforming a liquid feed into a spray of droplets, and a contact zone of the chamber, where the spray interacts with a hot drying agent. As a result of this interaction, moisture content of the drying agent increases due to liquid evaporation from the droplets.

B.14 SPRAY DRYER 4/02 B-123 B.14 SPRAY DRYER25,26,27 B.14.1 Background Spray dryers are control devices that reduce acid gas emissions. A spray dryer system consists of a slurry atomizer, reaction chamber, and a PM collection unit. The slurry is made of alkali sorbent (typically lime) and water. This slurry is injected into the flue gas in the ...

Duct Spray Dryer Process. The duct spray dryer process is very similar to the spray dryer process except that the slaked lime slurry is sprayed directly into the ductwork to remove the SO 2. No spray dryer vessel is used. The spent absorbent and the fly ash are captured in a downstream particulate collector.

partially dried droplets. The drying mechanism is defined by the process conditions, slurry composition and droplets trajectories in the dryer chamber [12]. References [13] and [14] reported the model of spray dryer including the overall mass and energy balances. The uniform gas conditions where assumed in the well-mixed dryer.

Spray drying involves a dispersion of slurry atomized into a spray of droplets that makes contact with hot air in a drying chamber. The evaporation of moisture rapidly forms a light-density, uniform powder which is discharged continuously from a cyclone. CinChemPro offers 24-hours-per-day, five-days-a-week spray drying production, with 24/7 operation available as required.

Spray Drying Process: Application and Feature

Spray drying is a process that uses hot gas to quickly dry a liquid or slurry into a dry powder. Many thermally sensitive products, such as foods and pharmaceuticals, as well as those requiring extremely constant, tiny particle sizes, favor this type of drying. The heated drying medium is air; however, nitrogen is used instead of the liquid that is flammable, such as ethanol, or if the …

The operation of the spray dryer is relatively simple. A slurry is atomized into the drying chamber in the form of droplets. When these droplets contact the warm gases, they dry to a powder. The hot gases, generated by either steam coils or a combustion furnace, enter the cylindrical drying chamber at various points, depending on the type of dryer.
