Circular fluidized-bed dryers can boost the capacity, energy efficiency and product quality when used in conjunction with other primary dryers Two-stage drying provides benefits from the standpoints of cost, energy savings, efficiency and product quality. This is especially the case…
Implementing microreactors in chemical production is quite a challenge. How these challenges can be met is described here At the heart of a chemical process is the reactor, where the conversion of reactants to products occurs. Depending on the need…
Compliance with air-pollution regulations requires ongoing effort. Follow these recommendations to assess competing options and optimize system design while minimizing cost and risk The goal of air-pollution control (APC) is to limit the amount of pollutants entering the environment. These…
With a focus on flowmeters, this article shows how advances in measurement technologies help safety system designers reduce risk and cost in their safety instrumented systems (SIS) design and lifecycle management Successful implementation and management of a safety instrumented system…
Combustion in industrial burners is a critical operation in the chemical process industries (CPI) for supplying thermal energy for heat transfer, fluid heating, steam generation, distillation, endothermic chemical reactions, metal melting and others. Burners are mechanical devices utilized for mixing…
