@vronald183

Hi. I'm a chemical engineer and I'm an expert in process modeling and simulation using Aspen Plus and Aspen Hysys. I read the job description and I can complete the project. If you're interested in my services let me know. Kind regards.

I am process simulation engineer with experience in carbon capture units and CO2 removal units simulation. Choosing the proper thermodynamics and optimizing the MDEA unit. Also simulated MDEA unit activated by piperazine. I can help you in this project and it will be totally optimized and with least power consumption. I can send you the simulation file

I have extensive experience modeling MDEA-based amine scrubbing systems in Aspen Plus for CO₂ removal from biogas and natural gas, with a strong focus on energy optimization. I will build a complete flowsheet including absorber, regenerator, lean-rich heat exchanger, pumps, cooler, and flash drums as needed, using the Electrolyte-NRTL property method with Henry's law components, which is the established thermodynamic package for MDEA-CO₂-H₂O systems. After inputting your raw gas composition, flow, pressure, and outlet CO₂ specification, I will run steady-state simulations and perform sensitivity studies on amine circulation rate, lean loading, absorber pressure, and regenerator temperature to quantify their impact on reboiler duty, pump power, and overall energy consumption. The results will be summarized in a concise technical memo highlighting base-case utilities, identifying the largest energy sinks, and recommending practical process tweaks for heat integration and efficiency improvement. Deliverables include a converged Aspen Plus file compatible with v12 or later, a PDF/Word memo with at least three operating envelopes compared in terms of GJ per ton CO₂ removed, and any supporting calculation sheets. Energy balances will close within 2%. . I am ready to begin immediately upon receiving your operating data.

I have extensive experience with Acid gas MDEA/CO₂/H₂S systems and will provide a detailed Hysys model along with technical memo optimizing for GJ/ton CO₂ removed. The model will include full heat integratiion and I will run sensitivity studies on amine flow, stripper temperature, and pressure. The simulation will meet your acceptance criteria for convergence, 2% energy balance closure, and 3+ sensitivity scenarios. I can deliver the fully documented .bkp/.apw file and a 5-page report highlighting energy sinks and savings. Estimated Timeframe: Base case in 2 days, sensitivity studies and final report in 5 days.

Hi, I am gonna develop a rate-based Aspen Plus (v14) simulation using the eNRTL property package to accurately capture the electrolyte chemistry and heat of absorption inherent in MDEA/biogas systems. My approach begins by constructing a full-loop flowsheet—comprising a high-pressure absorber, a flash drum for methane recovery, and a stripper with integrated lean/rich heat exchange—ensuring all energy balances close within a strict 2% tolerance. Once the base case converges against your specific gas composition and CO2 targets, I will execute automated sensitivity studies to map the operating envelopes, specifically focusing on how the L/G ratio and regenerator pressure influence the total GJ/ton of CO2 removed. Leveraging my experience in amine kinetics, I will conclude the project by delivering the .bkp files alongside a 5-page technical memo that identifies the largest energy sinks and recommends specific heat-integration tweaks to lower your reboiler duty. I estimate a 4-day turnaround for the initial converged model and an additional 3 days for the sensitivity analysis and final reporting.

I am a Chemical Process Engineer with direct operational exposure to amine-based gas treating systems. I worked in an ammonia plant where an a-MDEA absorption–regeneration loop was used for CO₂ removal from synthesis gas, which allowed me to understand not only the simulation side, but also the real operational behavior of absorber–stripper systems, lean/rich loading control, heat integration, and energy consumption drivers. In addition to plant exposure, I have developed Aspen HYSYS simulations for MEA and MDEA gas sweetening systems, and HYSYS is my preferred platform for this type of study due to its robustness in handling acid gas thermodynamics and amine packages. For your biogas CO₂ removal project, I will: • Build the full steady-state flowsheet (absorber, regenerator, lean/rich exchanger, pumps, flash drums if required). • Select and justify the appropriate thermodynamic package (Acid Gas - Chemical Solvents in HYSYS). • Ensure proper convergence and energy balance closure within ±2 %. • Perform structured sensitivity analyses on circulation rate, lean loading, absorber pressure, and regenerator temperature. • Quantify total duty in GJ/ton CO₂ removed and identify dominant energy sinks. • Propose realistic energy-reduction strategies without compromising CO₂ capture efficiency. I am ready to review your feed composition and operating data to define the simulation basis and move forward efficiently. Best regards, Kevin Segovia

I am a Process Engineer specializing in gas processing and carbon capture simulations. I can build the high-fidelity MDEA amine scrubbing model you’ve described, focusing specifically on your goal: minimizing the Specific Reboiler Duty (SRD). I will utilize the Electrolyte-NRTL (eNRTL) property package with the Amine-Property Method. This is critical for MDEA systems to accurately predict CO₂/H₂S loading, speciation, and the heat of absorption.I will build a closed-loop simulation including the Absorber (Rate-based for accuracy), Lean/Rich Exchanger (PHE), Stripper, and Flash Tanks for hydrocarbon recovery.I will automate a series of runs to find the "Sweet Spot" between Amine Circulation Rate and Steam Demand.

I am a Process Engineer with experience in natural gas processing and concept-phase onshore terminal design, including gas treatment systems and utility estimation. I can develop a complete Aspen Plus/HYSYS model of the MDEA-based amine scrubbing loop, including absorber, regenerator, associated heat exchangers, pumps, and flash units. I will select and justify the appropriate thermodynamic package, ensure proper convergence with tight mass and energy balance closure, and perform sensitivity analyses to quantify energy demand across operating scenarios. My focus will be on identifying key energy drivers (especially reboiler duty) and recommending practical optimization strategies without compromising CO₂ removal efficiency.
