Moving bed syngas conditioning: Modelling, in Applied Thermal Engineering, Volume: 62, Issue: 2, Pages: 809–822.1359-4311https://hdl.handle.net/10016/21680This paper presents a modelling approach for simulating tars and particulate (dust) removal in a moving bed heat exchange filter (MBHEF) in order to satisfy gas requirements of end-use syngas applications: engines and turbines. The two-dimension, adiabatic, steady-state proposed model accounts for two-phase (gas and solid) and neglects conduction and mass diffusion. Tars condensation is modelled through representative tar class lumps: phenol (class 2), naphthalene (class 4), pyrene (class 5). The model also considers tar concentration influence on the tar dew point. The filtration model is taken from literature. A sensitivity analysis is performed varying the particle size and the superficial gas velocity. Maps of temperature and tars abatement efficiency are presented. The simulation results indicate the feasibility of the use a MBHEF as tars removal equipment benefiting its advantages against others gas-cleaning methods with acceptable pollutant removal efficiencies, ranging 88e94% for ranges studied. Results also point out low gas velocities (0.5-1 m/s) and high particle size (400e700 mm) for reducing operational costs in MBHEFs with compact size.14application/pdfeng© 2013 Elsevier B.V.Atribución-NoComercial-SinDerivadas 3.0 EspañaTar removalBiomass gasificationSyngas cleaning-upesMoving bedHeat exchangeresearch articleFísicaIngeniería Industrial10.1016/j.applthermaleng.2013.10.010open access8092822Applied Thermal Engineering62AR/0000017284
