The gasifier was modeled using minimum Gibbs free energy method. Aspen Plus V8 was used for the modelling and simulation of the biomass gasification process. The biomass gasification was studied based on the dual fluidized-bed gasifier developed by the Vienna University of Technology, which has been successfully demonstrated in Güssing, Austria. Among the biomass utilization technologies, biomass gasification for combined heat and power is an attractive solution for utilizing biomass effectively. Counties all over the world are paying more and more attention to biomass because it can effectively reduce greenhouse effect due to its zero carbon dioxide emission.

Integration and optimization of an air separation unit (ASU) in an IGCC plant. Wang, M., Oyedun, A.O., Pahija, E., Zhu, Y., Liu, G. and Their Integration with Energy Conversion Processes. This indicated that Aspen Hysys ® has the thermodynamic packages and required tools to perform simulations in cryogenic processes at industrial scale.ġ. An absolute error of 1% and 1.5% was achieved between the simulated and observed the process variables(s). Each subsystem was validated separately and later on integrated into a single simulation. The ASU was divided into subsystems to perform the simulations. The obtained simulation and model was validated with the operational data from the Oxinor I of Air Liquide S.A Plant. In this paper, simulation of air separation units (ASUs) was studied using Aspen Hysys ®. One of these methods is Air separation process, which separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases by cryogenic distillation. Oxygen can be produced using several different methods. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and oxygen enriched air in a furnace or series of furnaces which is carried out using the injection of the air for oxidation the Fe and Si present in the raw material. The main process currently to separate copper from sulphide ores is the smelting process. The method used to extract copper from its ores depends on the nature of the ore.
