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.

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.

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?

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

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.

@kgengineeringsolutions
@kgengineeringsolutions 3 жыл бұрын
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

@kgengineeringsolutions
@kgengineeringsolutions 2 жыл бұрын
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.
