DIRECT ANSWERA storage tank mainly holds and transfers inventory; a buffer vessel mainly dampens pressure or flow variation. A scrubber instead performs gas-liquid contact or contaminant removal. Similar shells do not make the duties interchangeable.
Duty distinction
- Inventory/transfer versus dynamic buffering objective
- Flow variation, residence and pressure-control target
- Internals, level range, drain and vent philosophy
- Control, nozzles and system interfaces
Relevant manufacturing capability
- Project-specific storage-vessel manufacturability review
- Material, welding, inspection and pressure-test control
- Batch fabrication, documentation and large-equipment delivery coordination
Key notes
- Do not copy a vessel geometry across different process functions.
