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…
