DIRECT ANSWERIn addition to vessel basics, define the ammonia-refrigeration flow position, refrigerant state, circulation, liquid level, gas/liquid nozzles, oil drain, internals and control interfaces.
Refrigeration-system inputs
- System function and refrigerant state
- Normal/upset level and circulation cases
- Oil drain, separation internals and nozzles
- Controls, supports, inspection and site
Relevant manufacturing capability
- Drawing, datasheet and equipment-list manufacturability review
- Self-manufactured and coordinated-supply scope identification
- Technical, quality, document and delivery clarification
Key notes
- A generic ammonia storage-tank specification does not define a refrigeration vessel.
