Solve membrane fouling problems with high-shear filtration
Article Abstract:
Membrane-based separation techniques have been used widely by chemical process industry companies since roughly 1980. However, fouling has been, and continues to be, the biggest challenge limiting the use of membrane filtration as a viable, production-scale separations alternative. Fouling, which creates several problems, occurs when solids in the feed accumulate on the membrane and, over time, clog membrane pores and gaps. A number of high-shear membrane filtration technologies have been developed that solve these fouling problems. These include the vibratory shear enhanced process, dynamic membrane filtration and vortex flow perfusion.

Understand the potential of radiofrequency energy
Article Abstract:
Radiofrequency (RF) energy is being used in a broad variety of products and services in 2000. There are many applications of RF being used in the chemical process industries. However, the full potential of RF energy as a process tool for industry has yet to be realized. This is because a better understanding is required about the thermodynamics of RF heating in materials as well as electromagnetic field distributions and their control in materials during heating. A better understanding is also required about the material properties that interact with the RF fields to produce both thermal and, possibly, athermal effects.

Improve your existing process
Article Abstract:
Chemical engineers are akin to inventors in terms of process improvement. They must try to develop methods to achieve goals such as the reduction of manufacturing costs, improvement of existing plant capacity, addition of onstream time, minimization of waste generation and enhancement of product quality. A methodology for improving existing chemical processes is demonstrated that focuses on achieving a fundamental understanding of an already-existing process. Practiced correctly, this approach can potentially identify previously unrecognized process limitations or flaws.
