... ABSTRACT In this study, a numerical model for predicting the thermodynamic characteristics in a type C LNG tank with porous media coating is developed. The heat and mass transfer between liquid and vapor phases and the adsorption-desorption process between the boil-off gas and the adsorbent...

... and the migration of heavy metals at the sediment-water interface. It aims to reveal the law of adsorption and desorption of heavy metals at the interface of different media under the influence of water quality factors and to propose an improvement method to describe the isothermal adsorption at the interface...

... material to the vacuum. Hydrogen atom goes into metallic materials and permeated to vacuum chamber. We had reported that hexagonal boron nitride segregated onto stainless steel inhibits adsorption of hydrogen as measured by an electron-stimulated desorption (ESD) technique (Itakura et al., 1996...

... ABSTRACT Diffusion measurements and thermal desorption measurements have been performed on a X70 pipeline steel, in as received and normalized and quenched condition, after being hydrogen charged for 200 h at 100 MPa hydrogen gas pressure and 85°C. Numerical simulations based on the assumption...

... a removal of 87%. The desorption/re-adsorption phenomenon was clearly illustrated using the 95/5 soil samples. A plug flow reaction seemed to dominate the flushing process in which 60% of the total removal for the top 2/3 of the sample occured during the last 20 of the 80 pore volumes needed to achieve 100...
