Upflow moving packed bed reactors are widely used in industries for hydrotreating like hydrodenitrogenation, hydrodesulfurization, hydrodemetallization, etc. In these reactors, deactivated catalyst are removed from the bottom, and fresh catalyst are added from the top, gas and liquid phase move concurrently upwards. The catalyst removal occurs only once in a week and that too in small...

Upflow moving catalytic packed or expanded bed reactor are widely used in industries for hydrotreating of feeds with a higher level of contaminants including heavier feeds. In these reactors spent catalyst are replaced periodically by adding fresh catalyst at the top and removing spent catalyst from the conical bottom which supports catalyst bed. While the catalyst moves downwards...

Background of the study:
Indian paper industry is having an approximate share of 2.6% to the global paper production from ~813 paper mills. The chemical pulping process is widely used to produce paper using different types of raw material such as wood, bagasse, agro residue (wheat straw, rice straw) etc. The raw material is directly fed to a pulp digester along with white liquor to produce...

This paper reports the gamma scanning carried out to a rectifier column in one of the refineries in the Philippines. Several scans were performed to gather information on the operating conditions of the column at different sets of operating parameters using a 10-mCi Co-60 source and a 2-inch detector tandem. Result of each scan reveals the presence of blockage at several sections of the...

RADIATION TECHNOLOGIES FOR MEASUREMENT
Oral
In nuclear technique applications in industry, gamma scanning is recognized as a simple but very common and useful on-line investigation technique for diagnostics and troubleshooting in industry. Based on the principle of attenuation of gamma beam intensity according to the density of material while penetrating through the object, gamma scanning provides data or information about situation of...

ABSTRACT
Radiotracer residence time distribution (RTD) and computational fluid dynamics (CFD) are two methods (experimental and numerical) that can be used to study the performance of industrial process reactors. Although all the required parameters of a process vessel can be gotten using RTD methodology results should be used to validate CFD codes. CFD simulations does not only make the...
