Prozesssimulation Jobs

I need a complete DWSIM simulation that focuses on reducing the overall energy consumption of an MEA absorption–stripping system designed for post-combustion CO₂ capture from natural-gas flue gas. The emphasis is firmly on energy use—how we can cut the reboiler duty, lower auxiliary electricity demand, and generally make the flowsheet leaner without sacrificing capture performance. What I already have • Process description, feed compositions, and target CO₂ removal. • Basic thermodynamic and kinetics data for 30 wt % MEA. What I expect from you 1. Build or refine the full flowsheet in DWSIM (latest stable release). 2. Set up relevant optimisers and sensitivity analyses to pinpoint operating conditions that minimise total energy draw. 3. Supply the native...

I need a fully-parameterised ASPEN Plus V14.2 model that captures the key biological steps of anaerobic digestion so I can observe how the plant responds when I vary two levers: substrate concentration and hydraulic retention time. My core interest is methane production, so the flowsheet must report CH₄ flow rate (Nm³ h⁻¹ or similar) at every run and allow easy extraction of the data for comparative plots. Your task is to build, validate and hand over: • the working ASPEN Plus (.bkp) file with all relevant property methods and reaction kinetics implemented, • a concise run guide that shows where and how to change the two investigated parameters, and • a brief results note or dashboard (Excel, MATLAB or embedded Aspen Analysis) illustrating at least three op...
