Iodine absorber is a widely used purification equipment for purifying air in a nuclear power plant. In China, the common type is Ⅱ iodine absorber. Impregnated activated carbon is the main absorber within the iodine absorber. Because of the decays exothermic of radioactive iodine, heat is generated in the adsorption process. Carbon is a combustible material. Moreover, air is always supplied in ...

In recent years, extensive attention has been paid on the application of solar cooling for buildings. Amongst cooling technologies, low-temperature solar-driven adsorption cooling systems are emerging viable alternatives to electricity-driven vapour compression systems. They seem to have a promising market potential. The greatest challenge for their widespread use is the reduced thermal and mass ...

Introduction: Development of next-generation chemical processes that have zero emissions is a key environmental objective for sustainable development. The manufacture of H2SO4 by the air oxidation of SO2 to SO3 is an important technology where an opportunity exists for new catalyst development and process innovation by reducing emissions of unconverted SO2 in process reactor tail gases owing to ...

Recently adsorptive storage has been identified as the most promising low-pressure (3.5 - 4.0 MPa) alternative for storing natural gas for vehicular use. However in order to successfully implement this technology, the filling and discharge characteristics of the adsorbent bed must be well understood. Significant temperature changes that occur during adsorption and desorption retard the system ...

The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics (including a boundary layer between the electrolyte and the electrode particles). During discharge, the ...

The objective of the study is to investigate the chiral separation of Tröger’s base enantiomers using batch chromatography. Because of its resolution, chromatography is often the preferred method for chiral separations. The separation of Tröger’s base is resolved by using the COMSOL Multiphysics® software. It is modeled by one dimension geometry, having the length of the column set and computed ...

iCP (Nardi et al, 2014) is a software that couples two standalone simulation programs: COMSOL Multiphysics® and PHREEQC (Parkhurst & Appelo, 2013). The tool is ideal for applying multiphysics and geochemistry in Earth Sciences. Flexibility of the two coupled codes result in an extensive list of modelling areas, offering good opportunities for R+D. The iCP 1.0 is the version of the ...

An integrated numeric, thermodynamic, and experimental analysis work was conducted to find out the proper flow and transport parameters of combined chemical species for low-temperature gaseous nitrocarburizing of stainless steels in an industrial furnace built for thermochemical treatments. Such parameters are responsible for a steady thermochemical atmosphere essential for the anti-passivation ...

In the present work, COMSOL Multiphysics® software was used to solve a mass transfer based mathematical model (Stastova et al., 1996) which is a modified form of Sovova H.,1994 model. The modification has been brought about by introducing the term ‘Grinding efficiency’ in the model and the results of the this model has been compared with the theoretical results obtained by Duba and Fiori, 2015 ...

The complex internal flow field of a hypersonic air-breathing propulsion engine was modeled using COMSOL Multiphysics® software. This type of flow field can be found in a dual-mode scramjet engine. After creating the geometry, a 2D CFD simulation was run using the High Mach Number Flow physics interface in the CFD Module. A stationary time study was run and the results from the CFD simulation ...
