Compact Separation Systems
Compact Separation is a unit process that does not rely on (large, motion-sensitive) gravity-settling vessels. Compact separation technologies revolutionize topsides design by saving space and weight, while improving process performance.
Using cyclonic forces to provide phase separation – specifically oil, water, gas, and sand – this technology has the highest throughput-to-size ratio of any separation equipment. Cyclonic flow generates 100-5000 times gravitational acceleration (“g” force), which provides the following benefits:
- Reduced footprint and equipment volume requirements up to 90%
- Reduce equipment dry and operating weight up to 90%
- Motion tolerant: performance not subject to movement of the facility
- Reduced chemical consumption
- Reduced instrumentation
- Environmental improvement: reduced energy use, reduced heat loss, less raw materials, less wetted area for corrosion
Cyclonic unit processes are the core of the Compact Separation System (CSS) design. These technologies minimize size and weight of the modules, while providing process flexibility, resistance to facility motion, reduced chemical use, and simpler transport and load-out.
A staged approach combining discrete solid-multiphase, gas-liquid, liquid-liquid, and solid-liquid systems provides building blocks for fit-for-purpose designs. Compact Separation Systems are particularly well-suited for Early Production Systems (EPS), Extended Well Test (EWT) packages, and subsea processing.
Partial Processing is a methodology to apply CSS design to existing (brownfield) process facilities, and is particularly well-suited for gas or liquid debottlenecking.
