Improvements in cartridge dirt-holding capacity has led to new designs, as well as to new equations for filter selection and specification, which are linked to dramatic improvements in the time between turnarounds and filter changeout. Cartridge filtration serves…
Accidents do happen. While not everything can be predicted, addressing safety concerns throughout the design of a process can help to prevent accidents from occurring. Designing with safety in mind can also help to minimize potentially serious consequences…
Understanding why rupture disks fail can help ensure that they don’t Even with the best process design, the unexpected can happen. Anticipating this, rupture disks are often installed as the last line of defense against the over-pressurization of equipment used…
Consider these points when selecting and specifying equipment that separates material according to particle size Screening is an integral part of many dry material processes, ensuring an end product that is free of fine or oversized material, or in some…
New crystallization-system designs rely on previous successful installations and rules for scaling-up systems to adapt to slightly different conditions. However, guidelines or rules of thumb have underlying assumptions that might have been ignored when scaling-up a system during…
For companies in the chemical process industries, water is an indispensable utility. But the growing scarcity of quality industrial water, combined with stricter environmental regulations and the rising cost of wastewater treatment, have encouraged the conservation of water…
When Estee Lauder begin stirring up recipes for facial creams recipes in her kitchen some 70 years ago — the start of a $6.5-billion cosmetics empire that still bears her name — making high-purity emulsions was…
The need to transfer bulk-solids materials from the outlet of a bin or from a conveyor, to a process, truck, or another bin is ubiquitous throughout the chemical process industries (CPI). Transferring material using equipment designed to mechanically…
The dramatic jump in petroleum and natural gas prices over the recent years has created much impetus to reduce operating costs at chemical process plants. In processes that use either oil or gas for feedstock, such reduction can…
Energy consciousness and environmental awareness have transformed condensate from an inexpensive byproduct of steam distribution to a valuable resource that can substantially reduce operating costs. For process systems that use steam as the heat transfer media, improved condensate…
