Operators and engineers in the chemical process industries (CPI) who are responsible for the daily operations associated with sludge dewatering and drying equipment are undoubtedly aware that wastewater-sludge drying is not an easy task. A large number of the problems that arise during these operations are due to the sticky phase of sludge, which makes the drying of sludge as much an art as a science...

Adjustment and control of moisture levels in solid materials through drying is a critical process in the manufacture of many types of chemical products. As a unit operation, drying solid materials is one of the most common and important in the chemical process industries (CPI), since it is used in practically every plant and facility that manufactures or handles solid materials, in the form of powders and...

 Figure 1. A handful of ceramic proppants is shown here Carbo Ceramics This article covers permitting and directly related design issues associated with thermal processes using drying and calcining for the production of both proppant sand and ceramic proppants (Figure 1) as an illustrative example (see sidebar, "What are proppants"). The permitting issues vary significantly with air-quality...

This article covers permitting and directly related design issues associated with thermal processes used for drying and calcining, using the production of ceramic proppants as an illustrative example. While the magnitude of permitting issues varies significantly with air-quality attainment area status, oxides of nitrogen (NOx), carbon monoxide and particulate matter are always the major issues. With proper...

The CakeStand Tray Dryer utilizes a unique heat-transfer system that heats uniformly across all heating plates. The patent-pending design of the system features enhanced ergonomics through optimal...
September 1, 2012
Contact agitated dryers are used for drying wet powders, slurries, filter cakes, and applications where off-gases during the drying cycle must be contained. If the applications are also heat-sensitive, such as specialty chemicals, polymers, food products and pharmaceuticals, contact drying must take place at low heating temperatures, at residence times in tune with the tolerance of the product, and...

Among the most widely used technologies in the chemical process industries (CPI), spray drying involves dispersing a liquid or slurry in a hot gas to produce a dry powder product. A wide range of pumpable solutions, suspensions and emulsions can be used as spray-drying feeds. Spray drying allows processors to generate powders with precisely defined properties. By controlling process parameters —...

A vibrating fluidized-bed dryer from this company features multiple temperature-control zones that operate independently to permit a variety of different heating and cooling levels in the same continuous-drying system. The unit is ideal for gently drying grains...
November 1, 2011
With the ability to lower evaporation temperatures of liquids, the Rota-Cone Vacuum Dryer improves heat and mass transfer, and protects temperature-sensitive products. The vacuum dryers are an effective and...
October 1, 2011
Macrowave is a new drying system that uses radiofrequency (RF) energy to uniformly heat cake material and rapidly remove water without overheating. The system operates at a frequency of...
October 1, 2011
The Boono Paddle Dryer is an indirect dryer that can also be used for crystallization, coating, sterilization and calcinations. The wide...
September 1, 2011
The CakeStand Tray Dryer uses a unique heat-transfer system that ensures uniformity across all heating plates. The ergonomically designed unit has features, such as a pivoting...

Many solid materials can exhibit self-heating, which — if unchecked — can progress to a fire or even explosion. And even if the situation does not get that far, it is likely to affect the output of the process, in terms of product quality degradation, for example. Recognizing that your product in powder or granular form can self-heat is the first step in controlling the risks associated with...

The mixing-drying reactor can process substances of widely differing consistencies. The machine, which dries in a fine vacuum, is also very flexible with regard to the filling level. It is suitable for both homogenization of a mixture and also for more intensive...
August 1, 2011
The Planex System is a patented, horizontal paddle vacuum dryer developed for vacuum drying of wet powders obtained from a centrifuge or filter press. The system consists of a fixed cylindrical chamber with an eccentric agitator inside with two independent movements: it can rotate on its own axis and tangentially to the cylindrical chamber as well. This combined double...
