As an alternative to more complex and expensive technologies, the simplefilter is designed for many applications, such as hydrogenation, carbon filtration, catalyst recovery, prefilter for microfiltration and for filtration of APIs (active pharmaceutical ingredients) and intermediates. The simplefilter consists of…
Equilibrium stage simulations are the nearly universal process design tool for mass transfer columns that contact vapor and liquid in countercurrent flow. Whether the service is absorption, stripping, distillation, fractionation, quench or evaporation, equilibrium stage models make mass and heat…
Macrowave is a new drying system that uses radiofrequency (RF) energy to uniformly heat cake material and rapidly remove water without overheating. The system operates at a frequency of 40.68 MHz and features volumetric heating that provides instantaneous and uniform…
There are various reasons that make filtering necessary in processes. The raw materials might have impurities that require removal at the start of the process. After the initial mixing to produce the process slurry, the mother liquor could have…
Condensate pots are commonly used on the condensing sides of some reboilers, such as those that are heated by steam or refrigerant vapor. These pots provide a liquid seal that prevents uncondensed vapor from blowing out of the reboiler into…
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…
Good agitated Nutsche filter dryer performance relies heavily on the agitator design. The design of this companys agitator has a series of sharp curved blades with spaces at different centers of each arm. When moving or lifting filter cake product…
The CakeStand Tray Dryer uses a unique heat-transfer system that ensures uniformity across all heating plates. The ergonomically designed unit has features, such as a pivoting door, front and back access, and heating plates that hang from the roof, that…
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…
