i still dont understand in the calculator part. can you give a definition or a brief explanation? and why not directly use PYRO (RGibs). and if a want to define the size of the particle, where can i input the value? (the size of the particles are same in the simulation)
Sorry for asking many questions. Why did you connect a heat stream from RYield reactor to RGibbs reactor? ( while you could have set the gasification temperature at 750 in RGibbs without changing the mass flow of air).
no problem. Because I considered an adiabatic gasifier (neglecting heat loss). One can set a temperature value... one should then consider the heat requirement/excess in reactors.
I'm a student and your videos are a great help I must say. If you were to want to capture the carbon produced, how would you remove the unwated participants in the flue gas (anything except CO2, H2 and N2)? Thanks for the video!
@@amirrinto3495 I can't recall now any reference. There are many articles and books dealing with the mass balance of pyrolysis and gasification processes (E.g. google scholar and sciencedirect could be helpful).
(100-BIOMH2O)/100 calculates the ratio of mass of dry biomass to mass of wet biomass. Multiplying by BIOMC (ratio of carbon mass to mass of dry biomass) gives the weight fraction of C in wet biomass in %. Dividing by 100 gives the weight fraction of C in wet biomass (In R-Yield Reactor the fractions should not be in %.). I hope the balance has become clearer.
@@YC-qq8zu Because water content is not considered in the ultimate analysis in Aspen Plus. Without the calculation, the sum of the contents of the components in the reactor outlet would be more than 100% if biomass contains moisture.
Thank you for your video! Very helpful to me!! In C-2, should it be "MAIR = ER * (MC + 0.5 * MH2 - MO2) / 0.21", as one mole of H2 requires only 0.5 mole of O2 to burn completely🙂.
Hello, Thank you for your video! It helped me a lot :) BTW I have some questions about the equivalence ratio 0.5. What does this mean? and can you explain the equation? MAIR = 0.5*(MC+MH2-MO2)/0.21
Hello, you're welcome. The equivalence ratio is the ratio between the oxygen content in the oxidant supply and that required for complete stoichiometric combustion. ER Values close to zero correspond to pyrolysis conditions, while values greater than one indicate combustion conditions. You find a lot of information about this process parameter in the literature. The formula is a rearrangement of the ER formula. 0.21 is the fraction of O2 in air.
very helpful dear . m working in pyrolsysi and gasifcation ,,its realy helping
What will be the Fortran equation for the steam gasification? Just like here you used for Air?
C1 can be used, C2 needs to be adjusted.
What is the file you get data from? (I mean the file at 28:07) ?

Hello thank you sir it is very interesting.
Would you mind to explain more in detail the equation C2 ?
You're welcome
Which questions do you have?
@@kgengineeringsolutions juste explain each part of the equation

Thanks for the video!
Thank you:-)
Unfortunately, we haven't dealt with the topic yet, so we can't recommend any process at the moment.
thanks for your videos :D
is there a follow-up video for this case study?
You're welcome. No, we have not planned to create a follow-up video. In which direction would a follow-up video be interesting?
HI, where did you find the fortran calculation equation that used in this biomass gasification simulation?
These are balance equations. I wrote them myself. Have you found an error?
@@kgengineeringsolutions do you have reference to calculate these balance equations that i can refer?
@@amirrinto3495 I can't recall now any reference. There are many articles and books dealing with the mass balance of pyrolysis and gasification processes (E.g. google scholar and sciencedirect could be helpful).
@@kgengineeringsolutions both equation in C1 and C2 are the mass balance equation right?
@@amirrinto3495 C1 mass, C2 mole. Please note that 0.3 in C2 is the equivalent ratio. 0.21 is the fraction of oxygen in air.
Would you mind, please explain one of the equations in the C1? (for example : DECOMC = (100-BIOMH2O)/100*BIOMC/100
(100-BIOMH2O)/100 calculates the ratio of mass of dry biomass to mass of wet biomass. Multiplying by BIOMC (ratio of carbon mass to mass of dry biomass) gives the weight fraction of C in wet biomass in %. Dividing by 100 gives the weight fraction of C in wet biomass (In R-Yield Reactor the fractions should not be in %.). I hope the balance has become clearer.
@@kgengineeringsolutions May i ask why u did this? was means this step exactly? why should all components transfers into wet biomass?

Hi, Can anyone help me with my simulation for a biomass gasifier using eucalyptus wood chips? The reactor I need to simulate is a BFB type.
