How long does it take to reach steady state?

How long does it take a six-tray, 4-ft dia. deisobutanizer to achieve steady state? That depends on your definition of “steady state”. Some control experts regard 95% of “ultimate value” as a good definition, but how useful is that definition?…

Preventing Self-Heating and Ignition in Drying Operations

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…

This vacuum-drying reactor is flexible

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…

A fine way to separate solids from slurries

The Sweco Hydrocyclone Systems provide an economical and effective method for removing solid particles in the 4 to 100+ µm range from slurries. Hydrocyclones typically make finer separations than are practical with screening separators and at significantly higher capacities, says…

This multimotion dryer is kind to sensitive products

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…

This filter tackles difficult liquid filtration challenges

The new ZCore depth cartridge filter is said to offer improved performance, less downtime and reduced operating costs. The ZCore is especially suited for extreme applications where traditional cartridge filters are not effective, such as hot-water sanitizing, high-temperature chemical processing,…

A Clearer View Of Crystallizers

Improved understanding of crystallizer equipment and operation can aid purification efforts in the CPI Crystallization is a key purification technique for various sectors of the chemical process industries (CPI). Several approaches for industrial crystallization have evolved over time, and highly…

Compressed air filters for space-constrained applications

This new line of “top-loading” compressed air filters are designed to make element change-out faster and easier — even in the most space-challenged environments. The drain connections do not need to be disrupted during the change-out process. The proprietary, patented…

Liquid-Gas Coalescers: Demystifying Performance Ratings

Engineers working in the chemical process industries (CPI) sometimes have to deal with aerosol contamination issues in which liquid-gas coalescers are routinely employed. For example, liquid-gas coalescers are used to protect compressors, liquid-gas contactors, turbines, low-NOx burners, metering and instrumentation…
