    I need a brand-new Aspen HYSYS model that removes CO₂ from a natural-gas feed by using a monoethanolamine (MEA) solvent system. The scope begins with an empty flowsheet and ends with a working simulation I can build a full design package around. This study aims to optimise the removal of CO₂ from natural gas using an MEA-based absorption process in Aspen HYSYS. A sensitivity analysis will be carried out by varying key operating parameters, including absorber pressure, absorber temperature, lean MEA circulation rate, and MEA concentration. The effects of these parameters on CO₂ removal efficiency, energy consumption (reboiler duty), solvent circulation requirements, and overall operating cost will be evaluated to determine the optimum operating conditions.

    I need a full, steady-state Aspen HYSYS model for the industrial synthesis of methyl methacrylate (MMA). My priority is clear: model the entire process in enough detail to maximise overall yield while allowing Aspen to generate reliable capital (CapEx) and operating (OpEx) cost estimates. Once the simulation converges, I want the economics exported through Aspen’s costing tools (Economic Analyzer / Activated Economics workspace) so that I can see the breakdown of major equipment, utilities and annual cash flows. Scope of work • Build or refine the HYSYS flowsheet from raw materials to synthsis MMA from Natural Gas, Methanol, including reaction, separation and energy-recovery sections as needed for a realistic plant design. • Calibrate the ...

My main goal is to evaluate this feedstock against key performance indicators, so the model must let me read out syngas composition, tar formation and char yield cleanly at the outlet.

    I need a detailed Aspen HYSYS model that mirrors my pilot-scale absorber/stripper running 30 wt % MEA on natural-gas flue gas. You will start from the experimental runs I provide (gas composition, column dimensions, tray efficiency, heat-duty readings) and reproduce current performance in the simulator. Once the base case is validated, the task is to drive a systematic optimisation of solvent flow rate, temperature and pressure to minimise specific reboiler duty while keeping CO₂ capture ≥ 90 % and meeting product CO₂ purity targets. Because the work is simulation-centric, please anchor every assumption in HYSYS, document thermodynamic packages chosen, and keep a clear trail of the optimiser settings you test.

The goal is three-fold: cut the reboiler and condenser duties as much as practical, push overall CO₂ removal as close to 100 % as the equipment will allow, and translate those gains into a lower cost of capture. I will supply my current flow sheet, solvent properties, and plant operating envelope; you refine or rebuild the model, select suitable optimisation algorithms, and iterate until the combined objectives are met.

(2017) – Modelling, simulation and analysis of intensified regenerator (CO₂ stripper) for solvent-based carbon capture using rotating packed bed (RPB) technology Paper link (also attached to this project for direct download): The original model was implemented using Aspen Plus FORTRAN subroutines. The goal is to rebuild the RPB CO₂ stripper model natively in ACM, validate it using Cheng et al. pilot-plant data, and document the full modeling procedure. Scope (Summary) Develop a complete Aspen Custom Modeler (ACM) model of an RPB CO₂

    ...(STEP/DWG) and a bill of materials ready for procurement. Acceptance will be based on: 1. Thermal calculations matching the duty within ±2 % heat balance. 2. Surface shear rate and plate gap values that meet the fouling-factor limits I will provide. 3. Drawings that show clearances for plate removal and compliance with ASME or TEMA mechanical criteria. Typical tools on my side are HTRI, Aspen EDR, and SolidWorks; if you use other software, include the native files plus neutral formats. I will be available to answer duty-parameter questions promptly so you can iterate the model and lock down the final design....

    I'm looking for an artist to create a large cardboard beaver dam (over 2 feet) for an art cart. Hi I live in Aspen, Co. i’m willing g to drive to denver or closer to pick up the completed project which needs to be completed by Feb 4th. We are participating in a community event and are building an art cart themed around beaver conservation. We plan to create a beaver dam out of cardboard that will sit on a ski-mounted platform. A 10-year-old will be sitting on the platform dressed as a beaver, and there will be a sign above the dam sharing a message about protecting beavers. I’m looking for someone to help me build and paint a cardboard dam and sign for this art cart.—something sturdy, textured, and readable from a distance. I’ve made a rough sket...

    I’m preparing a feasibility package for a new fermentation-based bioprocess and need a clear techno-economic assessme...installation, and facility costs down to line-item level, including your assumptions and scaling factors. • A detailed OpEx model capturing raw materials, utilities, labor, maintenance, and waste handling, with sensitivity toggles for the main cost drivers. • A concise written report (≈10 pages) explaining methodology, data sources, and major findings, plus an editable spreadsheet or SuperPro/Aspen model so I can tweak inputs later. I’ll be on hand to answer process-specific questions and review an interim draft. The work is complete when the model balances, assumptions are documented, and the narrative makes it easy for non-engin...
