The liquid food product packaging are today predominantly made with board LPB type board (Liquid Packaging Board) composite formed by board, which offers mechanical strength, polyethylene, constituent responsible for protection against the passage humidity, and aluminum foil, which helps protect against oxygen flow. On the day, paper and board are words used as synonyms for each other. ...
Simulation of a Diesel Oxidation Catalyst Used in a NOx Storage and Reduction system for Heavy Duty Trucks

Department of Chemical Engineering, Lund University, Lund, Sweden
This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic oxidation catalyst mounted after a heavy duty diesel engine in a rig. The conversion of hydrocarbons is ...
Using COMSOL Multiphysics to Model Crust Development at the Surface of Whole Beef Meat Subjected to Hot Air Jet

Crust which develops at the surface of meat leads to reactions which affect food color, flavor and safety. Whole pieces of meat are only contaminated by microorganisms at their surface. Thus intense thermal treatment can inactivate pathogenic bacteria; however the associated high temperatures also lead to the formation of carcinogenic compounds. An experimental study of crust development at ...
A COMSOL Multiphysics® Software Interface with GEMS3K for Modeling Reactive Transport (Geo)Chemical Processes
O. B. Isgor , V. J. Azad ,
 Oregon State University, Corvallis, OR, USA
This paper presents a generic interface for reactive transport process modeling that was developed between the COMSOL Multiphysics® software Java API (transport model) and GEMS3K (reaction model). While the transport of different species, kinetics of dissolution/precipitation, system potentials, fluid and gas flow, etc. can be modeled in a complex chemical system with COMSOL® software, the ...

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 ...

This paper shows the solution of mathematical model of supercritical fluid extraction process, given by Sovova H., 1994, through COMSOL Multiphysics® software. Sovova et al., 1994 used this model for the supercritical CO2 extraction of grape seed. Extraction was performed with different specific flow rates and grade of grinding. Further Mira et al., 1996 and Mira et al., 1999 validated the same ...

The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. A configuration of denser CO2-enriched brine overlying lighter water leads to convective flow and the formation of gravity fingers ...

Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, oxygen concentration and ambient temperature on the self-heating behaviour of the dry coal dust sample has been ...
