To function properly at optimum capacity and efficiency, multi-pass trays must be designed so that the liquid and vapor flows are properly balanced. This article provides guidance on how to achieve that.
Purchasing lower-cost process equipment from vendors in developing nations can be an attractive proposition in times of economic austerity. When sourcing outside local channels, keep the points discussed here in mind to avoid costly problems that go...

Using computational fluid dynamics to design commercial-size batch and continuous reactors can eliminate subjective experience and empiricism, leading to better-designed, more-efficient units.
With so many types and options available, choosing the right control valve can seem daunting. Selection can be simplified by considering the process fluid, the service requirements, how the various valves function, and seeing how each valve will...
This article is aimed at the development of a framework for dust explosion prevention and mitigation that explicitly incorporates the principles of inherent safety. As distinguished from engineered and procedural safety features, inherent safety...
Many batch operations can be scaled up directly from the bench to the plant by developing the process and performing lab testing with the scaleup in mind.
Conceived more than seven decades ago, dividing-wall columns are now only gaining widespread acceptance. The reasons— the drive to save energy and advances in computer technology that have overcome the burden of doing complex column internal designs.
This continuous bottom-up approach allows precise control of the crystallization process to achieve size, distribution and quality goals, as well as realize the benefits of process intensification.
Identifying the right automation investments — those with low costs and high impacts — can result in millions of dollars in energy savings for petrochemical plants. <br>
