ANDRITZ Separation has been serving industries ranging from petrochemicals and soda ash to agrochemicals for more than a century. What all these chemical applications have in common is the importance of highly efficient thermal separation with either continuous or discontinuous…
Periods of reduced heat-transfer-fluid (HTF) system operation offer opportunities for mechanical integrity engineers to perform necessary maintenance. Here are suggestions for using the downtime for maintenance tasks. Safety These activities support ongoing safety of the HTF unit. Leak repairs. Repair…
An understanding of the available NOx-reduction strategies will help engineers to select the best technique to improve the performance of their combustion processes Pollution due to oxides of nitrogen — frequently abbreviated as NOx — is regulated with varying degrees…
Despite their nearly universal use in industrial combustion processes, valve trains are not widely understood. Here are some guidelines to help ensure their safe and effective operation Does your manufacturing facility have a smoke stack? If it does, it also…
Steam often provides the majority of heat, but its quality is not always carefully managed. Here are some tips on how to improve and maintain steam quality Plant operations focus on production activity, maintaining tight control on process algorithms, feedstocks…

This practical overview of ASTM standards can serve as a roadmap when selecting and evaluating heat transfer fluids Heat-transfer-fluid systems are often used for process heating to 500°F or higher. To accomplish heating above 500°F, steam pressure must be above…
Working with supercritical fluids poses challenges when designing heat exchangers. Some practical tips and precautions are presented here Industrial applications involving fluids at high pressure — pressure above the critical pressure of a particular fluid — are increasing in number.…
A new energy-storage process has begun operations at a large-scale pilot plant in Berlin, Germany. At the combined heat and power (CHP) facility of Swedish energy company Vattenfall, SaltX Technology AB (Hägersten, Sweden; www.saltxtechnology.com) constructed one 0.5-MW/10-MWh energy-storage unit using…
Adjustment and control of moisture levels in solid materials is a critical aspect in the manufacture of many chemical products. Drying can be defined as the vaporization and removal of water or other liquids from a solution, suspension, or other…
