Biomass Gasification and Carbon Capture Simulation -- 2

@providence78

I appreciate the opportunity to participate in the re-bidding for this Project, which requires knowledge in Reactor Design and Carbon Capture Simulation, using Aspen Plus. As a chemical and applied research engineer, my experiences have been related to applications such as Reactor Design, Azeotropic Distillation, C4-Isomerization, and Amine Units, including both MEA as well as MDEA Units. I have a PhD in Chemical Engineering, with professional experience in Distillation Column Design, Reactor Modeling for validating Conversions / Yield Estimates, and I am well verse with process simulation packages such as Aspen Plus, Aspen Hysys, PRO-II, ProMax, and DWSIM. I am experienced in writing technical reports/articles, and basic engineering packages. The proposed deliverables in-line with the project requirements is suggested to include: * Process Model set-up in Aspen Plus as per Design Basis. * Preliminary Material Balance / Stream Summary. * Simulation Model (.bkp file). The deliverables could be completed in about 30 days. The pdf format of the journal article is much appreciated. Note that a Rate-Based MEA simulation of Aspen Plus is quite involved and challenging. I will try to go through the bkp files that have been attached and see if there are any convergence or other issues. Please feel free to contact me, and I look forward to working on this opportunity. Best regards, SP

​Hello, ​As a Chemical Process Engineer with 8 years of experience, I specialize in rigorous Aspen Plus modeling for complex thermo-chemical processes. I have direct experience simulating biomass gasification and MEA-based carbon capture in industrial settings, making me uniquely qualified to deliver the high-fidelity validation you require. ​My Technical Approach: ​EFB Gasification: I will model the gasification process ensuring syngas compositions (CH_4, CO, CO_2, H_2) precisely match your reference journal data across the full temperature range (650°C to 900°C). I am proficient in handling non-conventional solids (proximate/ultimate analysis) and specifying decomposition blocks. ​MEA Carbon Capture: I will use the Electrolyte NRTL property method to validate absorption performance at 30\%, 50\%, 70\%, and 90wt\% MEA concentrations, ensuring the rate-based or equilibrium data aligns with experimental results. ​Integration & Sensitivity: Once validated, I will merge the models for a comprehensive sensitivity analysis to determine optimal operational parameters. ​Deliverables: ​Validated Aspen Plus (.apw) files. ​Technical Design Report including parity plots (Journal vs. Simulation) and a detailed breakdown of convergence settings and assumptions.

Hi, how are you doing? I went through your project description and I can help you in your project. your project requirements perfectly match my expertise. I have extensive experience with Aspen Plus. We are a team of Expert Chemical Engineers having 10+ years of industrial Experience dealing with different chemicals, we have successfully completed 1000+ Projects for multiple regular clients from OMAN, UK, USA, Australia, Canada, France, Germany, Lebanon and many other countries. I have gone through your project details and the work is DOABLE since it’s within our area of EXPERTISE. We have developed and implemented new chemicals for different purposes to reduce the cost and to enhance the efficiency. We have worked for chemicals on small scale in laboratory as well as on large industrial Scale. We can provide you timely and precise report as per your requirement. Further we can discuss in inbox about the detail of product.

Hi, I can help you simulate biomass gasification from EFB and carbon capture using MEA in Aspen Plus, and ensure the results match experimental journal data. I will: Validate biomass gasification – reproduce syngas composition (CH₄, CO, CO₂, H₂) at temperatures 650–900 °C based on the journal. Validate MEA carbon capture – match capture efficiency for MEA concentrations at 30%, 50%, 70%, and 90 wt%. Troubleshoot your existing simulations to fix any errors. Combine both simulations and perform sensitivity analysis on: Gasification temperature vs. syngas composition Steam/biomass ratio vs. syngas composition MEA concentration vs. carbon capture efficiency I will provide fully validated Aspen Plus models, clear documentation, and graphs for each analysis. Please share your current simulations, and I can start troubleshooting and combining them immediately.

Thank you for the invitation. As discussed, I will develop an Aspen Plus model for the MEA CO₂ capture system including the absorber and stripper configuration to simulate the CO₂ removal process and validate the results with literature data. Deliverables: • Aspen Plus simulation file • CO₂ capture performance verification

Hi there, ​I have reviewed your project for simulating Biomass Gasification (EFB) and Carbon Capture (MEA) using Aspen Plus. This aligns perfectly with my background as a Certified Aspen Plus & HYSYS Expert and Chemical Process Engineer. ​Why I am the best fit: ​Aspen Plus Mastery: I am a certified expert user with extensive experience in creating high-fidelity models. ​Relevant Projects: My graduation project involved Carbon Dioxide Emissions Reduction using Aspen HYSYS, giving me a deep understanding of carbon capture mechanisms. ​Research Background: As an MSc candidate, I have published research on process simulation and optimization, including sensitivity analysis for yield optimization. ​Troubleshooting: My current role as a DCS Operator Engineer has sharpened my ability to diagnose and resolve process errors. ​My Plan: ​Validation: Validate gasification syngas (CH_{4}, CO, CO_{2}, H_{2}) from 650^{\circ}C to 900^{\circ}C against your journals. ​MEA Capture: Validate capture efficiency for 30% to 90wt% concentrations. ​Analyses: Conduct sensitivity analysis for temperature, steam/biomass ratio, and MEA concentration effects. ​Integration: Combine and troubleshoot the .bkp files into a functional model. ​I am ready to start immediately and deliver a validated, error-free model within your 7-day timeframe. ​Best regards, Naser Elmoghazy
