Simulation of air-steam gasification of woody biomass in a bubbling fluidized bed using Aspen Plus: A comprehensive model including pyrolysis, hydrodynamics and tar production

Flowsheet Modeling and Simulation of Biomass Steam Gasification for Hydrogen Production

“…The results showed that 61 MW of hydrogen can be produced from 100 MW of woodchips, and 6 MW of power generation can be achieved. The important factors for the estimation of hydrogen production cost were the price of the biomass material, investment cost for the plant, [98] and the plant operation time per year. The hydrogen production cost of 54 € MWh -1 was achieved in this case study.…”

Multi‐objective optimization of green urea production

“…Gasification process is simulated using combined steamair as gasifying agent with all reactions and the kinetics data are taken from study of Pauls et al 21 For PEM electrolyzer is assumed with performances of 57%-64% LHV or 58-52 kWh of electricity per kg of H 2 . 22 By using electricity consumption data from the PV electrolysis process, the capacities of photovoltaic-based power plant and the battery necessary can be obtained.…”

The results of study into the effect of air­steam blast on the low­grade fuel gasification process

“…However, in known designs of gas generating units with a continuous bed, combustible gas produced from plant raw materials has calorific value not more than 10 MJ/Nm 3 [15,16]. Unlike this type of gas generators, modern gas generators with a fluidized bed have efficiency factor up to 80 % and calorific value of combustible gas reaches 18.5 MJ/Nm 3 [9]. However, they have an elaborate design requiring significant energy consumption in operation and maintenance.…”

“…[7,8]. Technological improvements should provide use of steam-oxygen blast at normal and high pressures [9] or oxygen-enriched air blast [10]. There are methods for improving efficiency of the gasification process by providing high temperatures in the active zone of the gas generator [11] and expansion of reacting surface area of fuels [12].…”
