Drying of chemicals is normally for storage and transport. Most of the times these are intermediate products that require further processing at other facilities. The requirements at these plants for industrial equipment are more around maintenance, safety/explosion risk, availability, and reliability.
All pilot plant units of INGETECSA operate under a light under pressure. Some equipment can operate under vacuum. Dust emissions are kept to an absolute minimum by using very high efficiency cyclones or bag house filters. Or even both.
All test equipment is designed explosion proof and most pilot units come with explosion panels.
