Vanmok DensePhase

Simulator for modeling pipelines transporting dense phase fluids such as CO2, Ethane etc..

Pipeline column separation refers to the phenomenon where the fluid undergoes a phase change in a liquid hydrocarbon pipeline due to change elevation or flow rate or temperature. The phase change could lead to bubbles or vapor pockets along the pipeline.

The Challenges

Simulating CO2 pipelines in the supercritical phase presents several challenges:

Phase Behavior Complexity: Supercritical CO2 behaves like a fluid but has properties of both a liquid and a gas. Its density, viscosity, and thermal conductivity can vary significantly, which makes it difficult to predict its behavior accurately. Accurately modeling the transition between liquid, gas, and supercritical states requires detailed equations of state and thermodynamic models.
Transport Properties: The flow properties of supercritical CO2, such as density, viscosity, and compressibility, are sensitive to both pressure and temperature. These properties are not linear and can lead to complex flow behavior that is hard to simulate, especially over long distances where temperature and pressure variations occur due to friction and heat loss.
Thermal Management: CO2 pipelines often experience temperature fluctuations that can lead to phase changes. Maintaining the supercritical state requires precise thermal management, and simulating heat loss or gain due to environmental conditions, as well as the heat generated by friction in the pipeline, can be complex.
Flow Regimes and Stability: CO2 flow in pipelines can transition between different flow regimes, from laminar to turbulent, depending on the flow velocity, pressure, and temperature. Accurate simulations need to model these transitions and predict when and where they might occur, which can be difficult due to the variable nature of supercritical CO2.
Pipeline Design and Pressure Management: Pipeline design for supercritical CO2 requires maintaining high pressures to keep the CO2 in the supercritical phase. Pressure variations can cause issues such as flow instability or even phase separation. Simulations must consider both steady-state and transient flow conditions, ensuring that the system operates within safe limits.
Leak Detection and Safety: Simulating leakage in supercritical CO2 pipelines is also challenging due to the changes in density and behavior of CO2 under different conditions. Since CO2 is heavier than air, it can accumulate in low-lying areas, leading to safety risks. Models need to accurately simulate the spread of CO2 and predict potential hazards.
Computational Complexity: Given the need to consider fluid dynamics, thermodynamics, and material properties in the simulation, computational complexity increases significantly. The need for high-resolution models and real-time simulations can be resource-intensive.

Need for a Simulator:

Simulator is needed to help address the challenges and address them during the design stage and operation of pipeline under simulated conditions. Accurate simulation of CO2 pipelines in the supercritical phase requires a combination of advanced modeling techniques and a detailed understanding of CO2 behavior under various operational conditions.
