The goal is to create a full-scope ASPEN Plus model of an Electro-Sustainable Aviation Fuel (eSAF) plant, focused on accurate material and energy balances and clearly defined process flows. Chapter 4 (methodology and process definition) is already fully completed. The new work must strictly follow the structure, methodology, guidelines, and deadlines provided in the attached document . This is mandatory. The model must cover the full process chain, including CO₂ conditioning, hydrogen production via electrolysis (SOEC, PEM, AEL), syngas generation, Fischer–Tropsch synthesis, upgrading, and thermal integration, using realistic operating conditions. In addition, the economic evaluation must be carried out using Aspen Process Economic Analyzer (APEA), integrated with the Aspen Plus model. The objective is to estimate CAPEX, OPEX, and key cost indicators (€/kg H₂, €/MWh H₂, €/t eSAF) in line with the thesis methodology. I expect a robust and clean simulation where: All streams, units, and blocks are clearly defined The model runs without manual intervention Recycle and convergence logic are properly implemented Naming conventions and structure are clear for future analysis Deliverables • ASPEN Plus (*.bkp) file with full flowsheet • Aspen Process Economic Analyzer (APEA) file / cost report • Process Flow Diagram (PDF, print quality) • Stream and utility tables (Excel or CSV) • Short methodology memo (2–3 pages) All work must be aligned with the thesis objective: a technical-energy-economic comparison of electrolysis technologies within a PtL process for eSAF production, not just a simulation exercise.

With over five years of experience in ASPEN Plus, I can confidently say that I am an expert in using this software for rigorous process simulation. I am well-versed in creating complex models with robust material and energy balances following a structured approach, like what your project requires. Moreover, my proficiency extends to utilizing Aspen Process Economic Analyzer (APEA) for economic evaluation, which is an essential skill set for your detailed cost analysis of the eSAF plant. My specialization aligns perfectly with your project requirements. In addition to my mastery of ASPEN Plus and APEA, I have a deep understanding of hydrogen/electrolysis systems and fuel synthesis processes. My academic training and practical experience in Power-to-Liquid processes make me particularly well-suited for this project. Not only will I ensure realistic operating conditions within the model, but I will also integrate necessary aspects like CO₂ conditioning, syngas generation, Fischer–Tropsch synthesis and thermal integration accurately.

With all due respect, my experience as a full-stack engineer does not align with the requirements of this project in terms of using Aspen Plus and APEA for modeling extensive industrial processes, specifically Hydrogen/electrolysis systems in fuel synthesis. However, I still believe I can be genuinely beneficial to your overall project idea. Fuel and energy are vital sectors for our world, and I may provide you with some crucial insights that escape industry insiders. Having worked closely with data pipelines, analytics, and ML components extensively, I am adept at handling large-scale datasets and extremely comfortable with complex systems. Therefore, I can assist in designing the databases for efficient storage and retrieval of your process's data for future analysis. My experience in automating operations combined with my proficiency in Excel can aid in streamlining the post-process work after the simulation is completed. Although I wish to offer you a comprehensive solution by undertaking your whole project, it would be honestly more appropriate to propose my support role to aid in restructuring or reanalyzing your data once the simulation has been completed by a person more skilled to do so. Keeping that intention intact, let us stand side by side for this "technical-energy-economic comparison of electrolysis technologies within a PtL process for eSAF production" project!

A full eSAF chain with SOEC, PEM, AEL, FT synthesis, upgrading, and APEA costing fails fast if recycle convergence and thermal integration are not structured correctly from the start. Built Aspen workflows where recycle-heavy hydrogen and syngas systems converged cleanly across multi-stage loops while keeping mass and energy balance deviation under 0.5%. Economic outputs stayed traceable directly into CAPEX and €/kg product metrics without manual patching. Your thesis structure already defines the methodology, so the critical part is translating that into a stable Aspen architecture instead of a disconnected simulation. I’d structure electrolysis blocks separately, normalize syngas conditioning before FT, then lock thermal integration only after recycle stability is verified in the base case. Which property method and FT reactor approach are you expecting for the core model Peng Robinson with RGibbs/RPlug, or something more constrained around kinetic conversion assumptions?
