Modeling and simulation of a wet hemihydrate phosphoric acid process

The wet hemihydrate phosphoric acid process was modeled and simulated with some assumptions and simplifications. The process consisted of grinding unit, reaction section, filtration section, and hydration unit and steady-state operation was assumed. Modeling was based on actual operation data and models for each unit were combined to form the overall closed system. Results of simulations showed that the model developed in this study described the behavior of actual plant very well. Various sensitivity analyses for the fundamental parameters were performed using the model. In grinding section, the effect of specific breakage rate on particle size distribution was examined. It was possible to regulate the temperature of slurry at reaction and hydration stage by using slurry recycle ratio. The effects of the recycle ratio on phosphoric acid concentration were also investigated.

Kinetic simulation of methane hydrate formation and dissociation in porous media

The vast amount of hydrocarbon gas deposited in the earth's crust as gas hydrates has significant implications for future energy supply and global climate. A 3-D simulator for methane hydrate formation and dissociation in porous media is developed for designing and interpreting laboratory and field hydrate experiments. Four components (hydrate, methane, water and salt) and five phases (hydrate, gas, aqueous-phase, ice and salt precipitate) are considered in the simulator. The intrinsic kinetics of hydrate formation or dissociation is considered using the Kim-Bishnoi model. Water freezing and ice melting are tracked with primary variable switch method (PVSM) by assuming equilibrium phase transition. Mass transport, including two-phase flow and molecular diffusions, and heat transfer involved in formation or dissociation of hydrates are included in the governing equations, which are discretized with finite volume difference method and are solved in a fully implicit manner. The developed simulator is used here to study the formation and the dissociation of hydrates in laboratory-scale core samples. In hydrate formation from the system of gas and ice (G+I) and in hydrate dissociation systems where ice appears, the equilibrium between aqueous-phase and ice (A-I) is found to have a “blocking” effect on heat transfer when salt is absent from the system. Increase of initial temperature (at constant outlet pressure), introduction of salt component into the system, decrease of outlet pressure, and increase of boundary heat transfer coefficient can lead to faster hydrate dissociation.

Software development for design and simulation of terraced wall and top fired primary steam reformers

In recent years, many research activities have been carried out on effective use of natural gas. The first step for this process, however, is converting natural gas to synthesis gas (syngas). Natural gas reforming process by means of a reformer furnace is commonly used for syngas and hydrogen production.

In this paper a windows-based software, RIPI-RefSim, is introduced. By using rigorous heat, mass, kinetic and thermodynamic models as well as taking into account the effect of catalyst shape, the software has been developed in order to provide reformer furnace simulation for syngas and hydrogen production. RIPI-RefSim can be used in three different modes (rating, simulation and design) and provides a detailed understanding of furnace performance, product characteristics, temperature, reaction rates and pressure drop profiles, effect of catalyst shape, and so on.
