Among the challenges of effective solid-liquid filtration is the accumulation of solids on the filter surface, which creates an increasingly dense mass that process fluid must push through. In many applications in the chemical process industries (CPI), a step-down filtration…
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?…
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…
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…
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…
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…
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,…
I have an ongoing dispute with a longtime colleague, Bob Miller. I said he ruined my new safety boots. He said he didn’t. Bob was a young, fearless distillation engineer at a time when our extraction engineer refused to take…
DriBoss evaporation equipment is designed for mining, water-treatment and oil-and-gas applications. The efficient DriBoss wastewater evaporator is supported by company-provided services, as well as by ancillary components such as pumps, valves, controls and sensors, which are also supplied by this…
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…
