Process skids are designed to contain a complete process system, a complete unit of operations or to organize a manufacturing process into logical units. All skids have the following characteristics in common:
- Portable design– self-contained units, built within frames, skid systems are easier to transport than traditional process systems
- Small footprint – process skid frames allow equipment layering. Piping, tanks, and necessary process equipment can be fit into a smaller footprint with a skid design
- Gathered process connections – process connections are gathered into one spot on the skid, making plant connections easier. In traditional process systems, connections are spread throughout the plant
- Controlled assembly – skids are typically built-in controlled conditions offsite. Existing operations are not affected by skid fabrication
- Accessible layout – skids are designed for accessibility, usually including a center hallway, and major pieces of equipment placed around the edge of the frame
- FAT testing before installation – Factory Acceptance Test (FAT) is performed before modular process skids are shipped to site. This eliminates on-site startup time.
