As a basic study of the two phases(gas phase and adsorption phase)or three phases(gas phase,liquid phase and adsorption phase)hydrocarbon equilibrium simulation in the porous media for the oil gas reservoir,the relative regression equations are completed by using the adsorption potential theory and the definition Dubinin adsorption potential,and through correlating the adsorption quantity and the adsorption potential,which measured for the different adsorbates in the different temperatures at the same type of adsorbent.
The two-phase equilibrium calculation model with the adsorption phase and freedom gas phase is developed using Flory Hugging Vacancy Solution Model(FHVSM)of gas adsorption. For two samples of dual gas mixture adsorption equilibrium,the adsorption equilibrium simulation calculation is completed after regressing the parameters of the pure component adsorption isotherm.
We have got some recognition about rule on control of equilibrium results and pulverulent ratio in leaching process by Multcomponent Multphase Equilibrium simulation research and leaching experiment.
A phase equilibrium simulation method for prediction of gas condensate phase behavior in porous media is presented, in which inter-facial effects of adsorption and capillary coacervation are considered.

Chemical thermal equilibrium simulation results show that O2 and HCl can greatly promote the mercury oxidization,and that HCl appears much more active than O2 during the mercury transformation.
With the water\|rock chemical equilibrium model WATEQ4F as the basic program and with a typical karstic water point in Pingdingshan mining area selected,the error transmission of the hydrochemical analysis data input in the water\|rock chemical equilibrium simulation was studied.
Copper matte converting has been mathematically described using the stepwise equilibrium simulation technique together with quadratic approximations of oxygen and magnetite solubilities in molten mattes.
Empirically, we use a multi-factor,market-equilibrium simulation model to determineoptimal tax rates and associated equity effects,particularly differences in landowner gains/lossesacross a heterogeneous region.
The oxidation behavior of HTGR oxidation resistant fuel elements has beens tudied under extremely accidental conditions and normal operating conditions through complex chemical equilibrium simulation. The calculated results show that the oxidation resistant fuel elements could effectively prevent fuel elements from oxidization under extremely accidental conditions, and the integrity of fue lelements could be maintained. However, under normal operating conditions, the oxida tion resistant fuel el...
With the water\|rock chemical equilibrium model WATEQ4F as the basic program and with a typical karstic water point in Pingdingshan mining area selected,the error transmission of the hydrochemical analysis data input in the water\|rock chemical equilibrium simulation was studied.Results show that the error in the hydrochemical analysis data can strongly effect the results of the water\|rock chemical equilibrium simulation,and different hydrochemical variables(errors)affect diff...
The prediction of trace elements speciation during coal combustion is very complex because there are numerous interactions existing in the multicomponent and multiphase system.Thermodynamic equilibrium simulation,which is a powerful tool,may provide a useful guide to the chemical fate of trace elements and their probable reactions in coal combustion process.A review about the thermodynamic equilibrium simulations applied to trace elements partitioning from coal combustion is given in...
