Learn how EOS-CG helps improve the profitability of your CCS projects

What are equations of state used for? Equations of State (EOS) are used to relate the densities of gases and liquids to temperatures and pressures. EOS are manipulated to calculate thermodynamic properties and predict fluid phase behaviours. The phase behaviours of fluids are applied within simulation software to model real-world processes. Hypothetical scenarios are created to determine a plant's most efficient settings to operate within. All modelled scenarios are dependent on the accuracy of the EOS. Ultimately, using an accurate EOS when simulating your process can reduce energy usage or Green House Gas (GHG) emissions as it allows the optimal settings to be...

Sweetening of sour gases with high-CO2 content using MDEA

For sour gas with high CO2 content, Sulfinol [1] or similar proprietary solvents are typically used. Sulfinol is a mixture of Sulfolane (a physical solvent), water and either DIPA (Diisopropanolamine) or MDEA (with or without Piperazine, an accelerator). Sulfinol has a high CO2 absorption capacity a...

Compressor blowdown calculations: Comparison of HYSYS BLOWDOWN vs the Depressuring Utility

IntroductionFluid temperatures can drop significantly during depressurization events and the heat transfer between the fluid and the vessel wall causes a reduction in the temperature of the material, which can lead to fracture if the temperature falls below the minimum design metal temperature of th...
