Packing and De-Packing Analysis is a key technology at the Flow Assurance Institute (FAC Institute) for Transient Simulation and pipeline system design in flow assurance. This service focuses on analyzing fluid packing and de-packing processes in long-distance multiphase pipelines, ensuring system stability during shutdown, startup, and transient operational conditions. By optimizing pipeline packing and de-packing strategies, we help clients ensure quick production recovery after an emergency shutdown while minimizing pressure fluctuations on equipment and systems, thus improving overall production efficiency and reliability.
Technical Principles
The core principle of Packing and De-Packing Analysis lies in the real-time simulation of gas-liquid multiphase fluids during pipeline packing and de-packing to predict dynamic changes in pressure, temperature, and liquid accumulation. Typically, in situations like production stops or unexpected valve closures, the system’s fluids are either compressed or released within the pipeline, leading to sharp pressure increases or decreases and transient fluctuations that can damage equipment. Packing and De-Packing Analysis enables engineers to identify and manage pressure extremes, ensuring flow assurance during shutdown or startup.
For instance, in gas transmission pipelines, Packing Analysis creates a buffer by slowly increasing pipeline pressure, allowing for continuous flow within a short period; conversely, De-Packing gradually releases stored gas by managing system pressure to ensure smooth transition to reception facilities. This analysis helps prevent liquid hold-up and sudden pressure drops in long-distance oil and gas pipelines, enabling smooth transitions to the next operational phase.
