Effects of bed aging on temperature signals from fixed-bed adsorbers during industrial operation

Predicting NOM Removal by Fixed-Bed GAC Adsorbers

Natural Organic Matter (NOM) normally exists in raw surface water as a complex mixture of organic compounds, mainly humic acids and fulvic acids. In water treatment plants, free chlorine reacts with NOM and forms a wide range of substances known as Disinfection Byproducts (DBPs). Granular Activated Carbon (GAC) adsorption is one of the best available technologies employed for the removal of NOM...

Mathematical Modeling of a Simulated Fixed Bed for Desalting Operation

Continue survival of the petrochemical industry in the face of advancement in processing technology must change for better performance. In doing so, the pre-treatment stage of crude, which include desalting will go a long way at improving the overall quality of the product obtained. It is in view of this that a mathematical modeling of adsorption of a fixed simulated bed for desalting operation...

Skeletal aging: from bench to bed side.

In this special issue of the Journal of Gerontology: Series A, we have invited experts in the fields of basic bone biology and clinical osteoporosis to review the current stage of our understanding of basic cellular and molecular mechanisms of skeletal aging, the appropriate animal models to study the process, the pathogenesis of age-related bone loss in humans, the latest clinical research on ...

Optimal Inlet Temperature Profile Strategies for Decaying Fixed Bed Reactor

Inefficient use of raw materials in most catalytic processes can be attributed mainly to the deactivation of the catalyst in chemical reactors. In order to achieve efficient use of raw materials, this paper addresses mitigation of deactivation through optimization of inlet temperature-time trajectories. The optimization of temperature profiles in reactors is one of the key problems in the synth...
