Surface adsorption isotherms and surface excess densities of n-butane in silicalite-1.
We present isotherms for the adsorption of n-butane on the external and internal surfaces of silicalite, in the temperature range of 320-400 K and at pressures up to 530 kPa. The isotherms were calculated using molecular dynamics simulations. A modified thermostatting algorithm, Soft-HEX, was developed for this purpose. The results for the external as well as the internal surface were fitted to...
متن کاملDiffusion of n-Butane/iso-Butane Mixtures in Silicalite-1 Investigated Using Infrared Microscopy
Zeolites of MFI-type belong to the most important zeolite structures in catalysis and are used in many shape-selective processes in petroleum refining industry, in particular for the kinetic separation of alkane isomers. Practically all important applications involve mixtures. However, due to the experimental difficulty, the number of experimental studies of mixture adsorption and diffusion is ...
متن کاملDriving Force for Nucleation of Multi-Component Gas Hydrate
Based on driving force for crystallization of one-component gas hydrate, in this report an expression for the supersaturation for crystallization of multicomponent gas hydrate is derived. Expressions for the supersaturation are obtained in isothermal and isobaric regimes. The results obtained are applied to the crystallization of hydrates of mixtures of methane plus ethane and can apply to ...

15 صفحه اولsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
