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...

The chemical process industries (CPI) have many applications that require classifying or separating solid materials. Examples of separation or classification processes include those operations that attempt to isolate specific material fractions according to particle size, scalp off the coarse fraction of a material stream, de-dust the fine fraction of a material stream or remove the contamination from a...

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...

Sulfur is a major contaminant in the oil and gas industry that exists in various forms and requires separation from both water and process streams. In recent years the removal of sulfur species has received increasing attention because of safety concerns, the need to reduce emissions of sulfur oxides (SOx), and the fact that sulfur harms the combustion properties of fuels. The “sulfur recovery...

 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...

Wet fluegas desulfurization (FGD), also known as wet-scrubbing, is a popular pollution-abatement technique for removing acid gases, such as SO2 and HCl from fluegas produced during coal-fired power generation and industrial combustion processes. Wet scrubbing is used in association with power generation, thermal oxidizers, kilns, incinerators, boilers, foundries and other combustion units. Also...

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 —...
