LNG Storage Tanks
KAF Cryogenics supplies vacuum-insulated LNG storage tanks for satellite plants, industrial energy supply and virtual pipeline receiving sites. Capacity, pressure, orientation and connections are selected for the delivery cycle and downstream gas demand.
Storage Capacity and Delivery Cycle
Storage sizing considers usable filling volume, daily and peak consumption, delivery frequency and operating reserve. Capacity is selected for the project and available tank model.
Double-walled tanks use a stainless steel inner vessel and a perlite-insulated vacuum space. Vertical or horizontal configurations are reviewed against foundation requirements, available height, access and filling and withdrawal interfaces.
Tank Pressure and Boil-Off Management
Stationary LNG storage MAWP options in the stated equipment range are 5–10 bar, with the final rating confirmed per model. An economizer can direct tank vapor to downstream gas consumption when pressure and demand permit. Pressure relief arrangements and idle-period conditions remain part of the operating review.
Filling, liquid withdrawal, pressure-building and economizer connections are coordinated with LNG receiving and gas supply equipment. Provide required gas flow, outlet pressure and site conditions when a vaporizer package is included.
Standards and Documentation
Stationary design requirements, including EN 13458 where applicable, and destination regulations are considered for the selected vessel. Drawings, datasheets and inspection or test records are defined in the equipment scope.

Frequently Asked Questions
How is LNG tank capacity selected?
Use the delivery schedule, gas demand, usable filling volume and operating reserve. The final model is reviewed against that storage duty.
What MAWP options are available for LNG storage?
Stationary LNG storage MAWP options in the stated range are 5–10 bar. The final model, rating and pressure reference are confirmed in the technical offer.
Does an economizer prevent all venting?
No. Vapor can be used downstream under suitable conditions. Long idle periods and relief conditions require a separate operating review.
Can the tank be supplied with regasification equipment?
Storage and regasification interfaces can be coordinated within the agreed project scope.
