H2SO4 is a very important chemical commodity, and indeed, a nation’s H2SO4 production has been a reasonably good indicator of its industrial strength for the last century or so1,2. Nearly 350 MM tons of H2SO4 was produced in 20143.The demand for H2SO4 in United States exceeds the supply ... En savoir plus
Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic ...

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research ... En savoir plus
In this paper, a 3D dynamic simulation for a portion of a metal hydride-based (LaNi5) hydrogen storage tank is presented. The model is based on heat and mass balances and considers coupled heat and mass transfer resistance through a non-uniform pressure and temperature sorbent bed. The ... En savoir plus
The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is an 85 MW, light-water moderated, research reactor that operates at low temperature and high pressure. The HFIR is presently scheduled to convert from a high enriched uranium fuel (HEU) to a low enriched ... En savoir plus
Mineral precipitation on to the quartz surface of the lamp jackets in UV disinfection process (fouling) has been recognized as a major problem for UV radiation delivery during disinfection operation. Fouling behavior was observed to be induced thermally and influenced by hydraulic ... En savoir plus
I introduce a model of fluidized reactor which, in presence of heterogeneous platinum-based catalyst, decomposes liquid formic acid producing gaseous mixture of carbon dioxide and hydrogen as the product. I treat the physical system as a (Class II) mixture of four constituents - namely ... En savoir plus
A packed bed reactor consisting of spherical catalyst particles in a tube was simulated numerically. The steady-state pseudo-heterogeneous model consisted of a pseudo-continuum representation for the heat and mass transfer in the reactor tube. The reaction source terms were evaluated by ...

At Oak Ridge National Laboratory (ORNL), COMSOL Multiphysics® software has become a preferred software for certain multiphysics applications in nuclear engineering. This presentation will highlight some of the ongoing activities in the following areas: (1) Highly enriched uranium (HEU) ... En savoir plus
Seco Tools produces inserts for machining metals. Roughly half the number of inserts Seco Tools produces are coated by Chemical Vapour Deposition (CVD) which extends the inserts lifetime in machining operations significantly. More than 10 000 inserts are coated on trays in each CVD run. ... En savoir plus
