The dryer shelf contains recirculated water that is temperature controlled to a specified set point to regulate heat transfer to the pans. Figure 1 shows the dryer and Figure 2 depicts the equipment layout. [javascriptSnippet ] Drying starts once the dryer door is sealed and the vacuum supply valve is opened.

During any drying process, all additives and solvents have to be removed from the solid material without changing its original chemical composition. In essence, there must be no changes to the molecular …

Then, the plant initiated the next dryer regeneration. The hot regeneration gas caused the caustic-amine-impregnated molecular sieve to set like concrete. The dryer had to be removed from service and the agglomerated sieve jack-hammered out. No one had appreciated that it was essential to keep level under control in the wash section.

As with any type of process equipment, however, the reliability of a rotary dryer and its ability to consistently dry bulk solids hinges on proper operation and maintenance of the unit (Figure 1). This article covers best practices for rotary-dryer operation that will help to maximize the service life and reliability of the rotary dryer, while ...

Rotary dryers are often called the 'workhorse of chemical dryers' and fall in the most widely used class of continuous dryers in process industries. It consists of a slowly rotating slightly inclined cylindrical shell fed with moist solid at the upper end. The material inside a rotary dryer flows along with the rotating shell, gets dried ...
