The catalogue says what equipment can do at rated conditions. The plant needs to know what the whole system will do when the load changes, a truck is late or one train is down for maintenance.
Four figures to have before design
- Average and peak hourly flow.
- Hours or days of reserve required.
- Pressure and temperature at the handover point.
- Land area, safety distances and local ambient conditions.
Only then can storage capacity, number of vaporiser trains, redundancy philosophy and delivery cycle be set. If monthly volume is simply divided evenly, the system may have enough total energy but too little flow at peak hours.
Mobile or fixed?
A mobile configuration suits commissioning, temporary demand or an early phase when the load is not yet stable. A fixed station suits a clear long-term load and deep integration with the plant. A transition path can be designed, but the interfaces must be planned from the start.
Allow for things going wrong
The plan has to answer what happens at power loss, when the vaporiser derates, when an instrument fails or when a delivery is late. That list determines back-up equipment, emergency shutdown logic and minimum stock.
