I completed successfully my undergrade thesis .I mailed u for help but u couldn't help me directly as u have paid group.I am the first of my Mechanical Department of CUET,Bangladesh, done the thesis on ASPEN PLUS simulation .So that time was difficult for me to work on this topic lonely.But Ur free utube videos as well as @HotSpot videos helped me a lot throughout last one year to did my thesis.Thank u very much.
Thank you. Can you make a video on Kinetic model approach in which we consider formation of heavy compounds. Please make a video on Modeling Gasification Based on the Kinetic Approach with RCSTR, RPLUG, and other User-Defined Blocks.
I wanted to know that are the ASPEN model results (like mass fraction, Mole fraction.....etc) aligned with the experimental results from the literature?? Also I request you to please prepare a separate video on change in model results upon changing different parameters like AFR, steam to biomass ratio, temperature, equivalence ratio..etc. and also how to plot graphs in Aspen Plus.
Dear Sir, It is so great to see your efforts on this aspect of research. A humble request, can you please try to simulate a case of biomass gasification using ansys fluent?
The model is based on Gibbs energy minimization. I would say that the model can be used to find out what is possible with the process depending on the input materials, process temperature and pressure. In reality (experiment) a process is generally dependent on different rates (for example conversion rate, etc ...). As soon as I find time, I make a video about sensitivity analysis and plotting.
Thanks for this helpful video. I have a question about simulation of an entrained flow gasifier for biomass in Aspen Plus. What types of components should I use?
Thanks so much for the great example.It's very comprehensive.I would like to ask if there are any examples of biomass hydrothermal liquefaction to produce biocrude.
@@jacknorman8798 Thank you very much. Unfortunately, we haven't dealt with the process yet. I think it will be difficult to simulate the process with RGibbs. I would rather simulate kinetics if a model is available or use rstoic if experimental data available.
Why was the ultimate analysis of the biomass not changed downstream of the dryer? Does the ultimate analysis not include the H and O atoms bound in water and driven off by the dryer?

Thank you!! very useful stuff. I am curious what is the purpose of using RYIELD reactor in the gasifier unit? why RYIELD REACTOR GIVE OFF ENERGY (Q=32478) in such case? is there any reaction going on?
Thank you. To my knowledge the GIBBS reactor cannot calculate biomass gasification directly. Therefore, this manipulation with RYIELD reactor is necessary as a preliminary step. Biomass is decomposed in RYIELD reactor. Hence there is a change in the energy content of the material.
Hello, sir. Why can you use the data in drybiomass stream for the yield distribution of Ryield reactor in your video? I hope I can get your reply. Best wishes.
Hello Sir, In the video Aspen Plus Simulation for straw gasification have you incorporated the Equivalence and air to fuel ratio if yes where do we need to put them in the simulation. Thanks.
Hello Robby, I didn't enter the ratio anywhere. I used the sensitivity analysis to find out at which air mass flow the energy balance is closed without taking heat loss into account.

Hello, it is a little bit tricky. I understood that biomass is given a molecular weight of 1 in Aspen Plus. We assume we convert 1 g of biomass to H2O. So we get 0.053093 mole of H2O. 0.053093 mole is the result of 1 g divided by the molecular weight of water==> 1 mole biomass --> 0.053093 mole H2O

Hello, loved to watch your vid with effort. I have a question, why molar mass of biomass is 1kg/kmol? Can you tell me the reason why?
Hello, thanks.
Aspen Plus treats the non-conventional biomass as if it has molecular weight of 1 kg/kmol.
If I use another BIOMASS as input in this model, then will I get results aligned with the experimental data???

H and O in the ultimate analysis are not from water, they are from dry biomass that does not contain H2O molecules.
