The use of gasketed plate-and-frame heat exchangers has gained tremendous acceptance in the chemical process industries (CPI) over the past 20 years due to their high heat-transfer coefficients, compactness and low cost. However, it is important for the engineer who…
The world’s largest pharmaceutical conference and exhibition, Interphex, will be held at the Jacob K. Javits Convention Center in New York from March 17 – 19, 2009. On the show floor, attendees will find equipment and solutions for drug manufacturing,…

Here, we present criteria needed for the intelligent, effective specification of trays for a distillation or stripping column. Among the key parameters and accessories during specification are column diameter, tray spacing, number of trays, number of passes, type of downcomers,…
Here, a design approach for continuous stirred-tank reactors is outlined for both reversible and irreversible second-order reactions Multiple CSTRs (continuous stirred-tank reactors) are advantageous in situations where the reaction is slow; two immiscible liquids are present and require higher agitation…
Ceramic filters are well suited for high-temperature processes that are subject to strict emissions limits, including those for dioxins About Incineration Incineration processes are being widely used more and more to deal with the disposal of waste materials. In many…
In today’s fast track schedules for constructing new capital facilities, the process of designing, delivering and erecting piping often falls in the project’s critical path. This is particularly true for facilities constructed in emerging economies, where the facility generally resides…
Frequently, in chemical processing equipment it is possible to place the shaft support bearings in the chemical that is being processed. In some cases, this precludes the use of oil- or grease-lubricated bearings because the operating conditions are not conducive…
Portable mixers for pilot plant and small-scale production processing The PB Series pharmaceutical mixers (photo) feature a lightweight frame motor with a right-angle drive, 316 stainless-steel wetted parts, dry running mechanical shaft seal with CIP (clean in place) capabilities and…
