Aspen Plus: simulation of a biomass gasification process (straw gasification)

[@kgengineeringsolutions]

Thank you for your comments. If I find reliable data, I will upload a kinetics-based simulation in November.

Thank you very much.

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.

[@samuelmbugua975]

I've learnt alot from your videos over the past few months. Keep up the good work.

[@avinashdasam1894]

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.

[@lizatanggw2967]

Thank you so much! I may not pass this task without your clip video.

[@afiffaishal1]

love dat backsound!!! thank you so much!!! i hope u make the other video with your oral explanation...

[@murtazamodi24]

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.

[@nermeenrabee4574]

Yes plz till us and howa to get %vol of any component vs temp or air to fuel ratio how to calculate it

thank you sir that was very helpful

[@pmfitline_yeongrok]

The video was very helpful. What paper was the simulation based on? I would like to check the results against the paper.

[@rachelleamundson392]

Hello I am experiencing an error replicating your simulation with a biomass feed of corn stover. The error that Aspen Plus 10 is registering is that the elements are not in balance. Do you have advice for this error?

[@kgengineeringsolutions]

Hello, could you send me your model?

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?

[@kgengineeringsolutions]

Thanks for your comment. Once I find a well-described fluent approach, I'll make a video about it.

[@oo-xe1yk]

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?

[@kgengineeringsolutions]

Hello, thanks. Aspen Plus treats the non-conventional biomass as if it has molecular weight of 1 kg/kmol.

[@MichaelGustavo-c9p]

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?

[@kgengineeringsolutions]

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

[@murtazamodi24]

If I use another BIOMASS as input in this model, then will I get results aligned with the experimental data???

[@kgengineeringsolutions]

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.

Thank you, I have a question. What type of gasification model in this simulation( Fluidized bed, moving bed, fixed bed, entrained flow or etc.)?

[@kgengineeringsolutions]

You're welcome. This is a thermodynamic simulation, can be considered as a step before choosing the reactor type.

[@zeinabmohseni5875]

Thank you for your comment. I honestly don't know where to start in this topic. If you have any literature about the process, please share it with me. Then I'll write you if I can do something.

[@mingyangdai9783]

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.

[@kgengineeringsolutions]

This is an approach often used in Aspen Plus for such processes. Or do you see a mistake?

[@godschild5030]

hi there may i know what type of straw did you refer to for this simulation?

[@kgengineeringsolutions]

Hi I took the analysis from the paper with the DOI 10.1016/j.ijhydene.2021.04.076 It was only mentioned that the straw was collected from Jiangsu Province in China

[@robbymcallister4]

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.

[@kgengineeringsolutions]

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.

[@nkennaamadi1663]

Thanks for the great example, do you have anything related to pairing the gasifier with a steam turbine and also a fuel cell for an IGFC?

[@kgengineeringsolutions]

thank you, unfortunately not at the moment

[@darioburbano9193]

Hello, I have a question, Why does the coefficient in the first reactor is 0.055093 for products? Thanks

[@kgengineeringsolutions]

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

[@darioburbano9193]

@@kgengineeringsolutions Thank you very much for your answer, but how realistic is it to assume the molecular weight of biomass equals 1?

[@kgengineeringsolutions]

@@darioburbano9193 With pleasure. As far as I know, this is the only way to calculate conversions of biomass in Aspen Plus (if not taken the decomposition route).

[@BJtankman8964]

I think the coefficiency for water should be 1g x 8.32% /18 = 0.004622

[@moaaz2928]

Thanks for your great effort, I have a question tho, is it possible to have a dynamic biomass gasification? or it's not feasible?

[@kgengineeringsolutions]

You're welcome. Unfortunately I do not know

[@fuqionglei4727]

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?

[@kgengineeringsolutions]

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.

[@mrct93]

Hi... I have the same doubt... how is the reactor giving energy (Q=32478), oncee Q>O (endo)?

[@fatemehrajaee533]

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?

[@kgengineeringsolutions]

This is a difficult issue. Unfortunately I don't know at the moment.

[@angelgozalo1864]

why is the molecular weight of the biomass 1 kg/kmol??

[@kgengineeringsolutions]

This is assumed by aspen plus.

[@jacknorman8798]

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.

[@kgengineeringsolutions]

@@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.

This depends on the thermal properties of the straw to be used and the process parameters. With Aspen Plus one can determine the energy balance
