Over the years, the demand to energy density and performance of batteries from new applications has led to the development of new generations of batteries, including secondary lithium-ion batteries. These batteries are foreseen to play an important role in the electric vehicle market, which is predicted to grow significantly in the coming years. For this reason, there is an intense race among leading manufacturers worldwide for developing proprietary Li-ion batteries with superior performance characteristics.... http://www.che.com/processing_and_handling/sep_gas_solid_and_liquid_solid/dryers/Spray-drying-by-rotary-atomization-of-lithium-ion-battery-materials_5658.html
The problem of cleaning coke-cooling wastewater has vexed engineers for decades, but effective solutions have remained elusive. Without a low-cost technique to treat coke-cooling wastewater, environmentally inocuous production of petroleum is impossible. The process discussed here represents an improved method for purifying coke-cooling wastewater and offers a path toward cleaner petrochemical production.... http://www.che.com/processing_and_handling/sep_gas_solid_and_liquid_solid/scrubbers/Purifying-Coke-Cooling-Wastewater_5498.html
Most members of the highly regulated chemical process industries (CPI) are aware of the growing worldwide attention focused on the issues of climate change, air and water pollution and the supply and protection of natural resources. For this reason, air-pollution-control scrubbers play an integral role in most chemical processing facilities. However, the economic downturn caused... http://www.che.com/processing_and_handling/sep_gas_solid_and_liquid_solid/scrubbers/Scrubbers-Are-You-Ready_5377.html
Drying as a process is one of the most energy-intensive unit operations on the planet. Add to that the fact that dryers are used extensively throughout the chemical process industries (CPI) and it becomes obvious that there ought to be more attention paid to reducing the energy consumption and upping the “green” ante of drying processes. Unfortunately, the current economy is putting any such projects and plans on hold for many processors. Drying equipment experts, however, say it doesn’t have to be this way a... http://www.che.com/processing_and_handling/sep_gas_solid_and_liquid_solid/dryers/Building-a-Better-Dryer_5320.html
Evaporation of moisture or volatile organic compounds (VOCs) from bulk solids usually takes place in two stages: one in which the drying rate is constant, and the second in which the rate decreases over time. Devolatilization during the first stage is rapid and can be readily accomplished in flash, spray, or fluidized bed dryers. In the second stage, however, the VOC or moisture removal rate is diffusion limited, and several hours of residence time are often necessary. To meet low moisture or VOC targets, two unit operations may be required. An economical way to provide the extended residence time required for slow, diffusion-limited drying is to use a bin or silo that has been modified to allow injection of a sweeping gas and, in some cases, to provide heating. These unit operations, which have a variety of names including gravity dryers, offer numerous advantages.
When it comes to dust collection in the chemical process industries (CPI), there exists a wide variety of needs. For example, folks in dyes and pigments have a different set of dust collection challenges than those in the pharmaceutical industry, who have differing requirements from processors working with paints and varnishes. However, any and all chemical processors can boost process efficiency by... http://www.che.com/processing_and_handling/sep_gas_solid_and_liquid_solid/Newsfront-Dust-collection-Clean-up-your-act_4364.html
