A comparative study for biomass gasification in bubbling bed gasifier
The steady-state equilibrium model of bubbling fluidized bed gasifier for the biomass gasification process was developed in Aspen HYSYS V11. If a convenient bubbling bed gasifier model can be created; chemical composition, exergy, and lower heating value of syngas can be examined by performing a case study on the developed model.

Simulation of biomass gasification in bubbling fluidized bed reactor
Table 2 lists the operating conditions during the gasification experiments in the pilot scale reactor. The bed temperature was maintained between 700 and 860 °C and the equivalence ratio (ER) between 0.17 and 0.35. The ER was calculated as the ratio between the O 2 supplied to the gasifier and the stoichiometric O 2 for each biomass and …

Cost estimating for chemical engineering plant design
When a reactor is either heated or cooled, cost it as the sum of the cost of a heat exchanger plus that of a vessel. For a plug flow reactor, you calculate the area from the tube diameter, length and numbers. For a fluidized bed reactor use the Q and Ts to calculate the area as for other heat exchangers.
