چکیده
The production of synthetic natural gas (SNG) via methanation has been demonstrated by experiments in bench scale bubbling fluidized bed reactors. In the current work, we focus on scale-up reactor, and a circulating (CFB) is designed with variable diameter according to characteristic methanation. critical issue removal reaction heat during strongly exothermic process As result, an interconnected (BFB) utilized connected reactor order cool particles maintain system temperature. A 3D model built, influences operating temperature H2, CO conversion CH4 yield are evaluated numerical simulations. instantaneous time-averaged flow behaviors obtained analyzed. It turns out that products high concentrations received at CFB outlet. kept under control using cooling unit, steady state thermal behavior achieved effect BFB reactor. rate power significantly affect performance This investigation provides insight into design operation feasibility for confirmed.

Simulation for Supporting Scale-Up of a Fluidized Bed Reactor for Advanced Water Oxidation
Simulation of fluidized bed reactor (FBR) was accomplished for treating wastewater using Fenton reaction, which is an advanced oxidation process (AOP). The simulation was performed to determine characteristics of FBR performance, concentration profile of the contaminants, and various prominent hydrodynamic properties (e.g., Reynolds number, velocity, and pressure) in the reactor. Simulation was...

متن کاملModelling and Simulation of Nonlinear Interconnected Large-scale Systems
A novel modular approach to the modelling of nonlinear interconnected complex systems is introduced in this paper. In the approach, a complex system is decomposed into selfcontained easily identified modules to achieve easy linking of individual models. Our proposed approach to modelling differs from the traditional approaches in the following important aspects: (i) it is nonlinear, modular-bas...
