I’m assembling a small team of Pakistan-based chemical engineers who work confidently in Aspen HYSYS and Aspen Plus. Your core mission is to build and refine steady-state or dynamic process models, push them through rigorous optimisation, extract clean datasets for further analysis, and then translate everything into a clear, professional technical report that a non-specialist stakeholder can still follow. Typical assignments will include: • Creating or updating complete Aspen HYSYS / Aspen Plus files for new and existing flowsheets • Running sensitivity studies and optimisation routines to improve energy use, yields, or economics • Generating concise mass- and energy-balance tables, convergence screenshots, and annotated flowsheets • Writing a polished report that explains methodology, key assumptions, model results, and recommendations Acceptance criteria: 1. Simulation files open error-free in the stated Aspen version and converge under the documented conditions. 2. All optimisation variables and constraints are listed and reproducible. 3. The final report (Word or PDF) summarises objectives, methods, results, and actionable insights, with figures and tables properly labelled. If you have a solid chemical-engineering foundation, practical experience across process, materials, or environmental applications, and can back it up with crisp technical writing, I’d like to see examples of your previous Aspen work along with a brief note on your availability.

@tayabChemEngr

I am a Pakistan-based chemical engineer with extensive experience using Aspen HYSYS and Aspen Plus for both steady-state and dynamic simulations across petrochemical, pharmaceutical, and environmental applications. My typical workflow includes building or updating full flowsheets, performing sensitivity studies and optimization routines to improve energy efficiency or economics, and extracting clean mass and energy balance tables along with convergence screenshots. I then translate these technical results into clear, professional reports that explain methodology, key assumptions, findings, and actionable recommendations—structured so that non-specialist stakeholders can follow the logic and decisions. I ensure all simulation files open error-free in the specified version and converge under documented conditions, with all optimization variables and constraints fully reproducible. I can provide examples of previous Aspen work upon request and am available immediately for ongoing assignments. Please share your specific project needs and I can begin right away.

What makes me the best candidate for this project? I have experience with engineering software, technical analysis, process modeling concepts, and data-driven optimization workflows. I can support Aspen HYSYS and Aspen Plus projects by developing structured simulations, analyzing results, and preparing clear technical documentation. This project interests me because it combines process engineering, simulation, optimization, and technical communication. I can help create and refine process models, perform sensitivity analysis, organize mass and energy balance data, document assumptions, and prepare professional reports that clearly explain results and recommendations. I can start immediately. Milestones: - Requirements & Planning - Simulation Development & Optimization - Testing & Delivery Timeline: Starting from 1–2 weeks. Budget: Starting from $500. I look forward to discussing your project.
