VT LNG SERIES

FULL EN 13458

Chart Ferox, a.s. VT LNG series cryogenic tanks are designed in accordance with all LNG requirements for safe, easy and economical operation. Many of the features have been incorporated in close collaboration with leading LNG companies.

VT LNG series tanks are vertical, stationary pressure vessels with vacuum perlite insulation for long-term efficient storage of LNG under pressure.

VT LNG series are available in capacities from 3,000 to 60,000 liters with pressures of 18 bar. Sizes with capacities over 60.000 liters upto 80.000 liters are available with pressures of 17 bar. Tanks with capacities over 30.000 liters with outer vessel diameter 3.000 mm are available also with pressure of 11 bar.

Product Highlights
  • Built in accordance with EN 13458 and conforming to directive 97/23/EC (PED)
  • Modular external plumbing design minimizes number of non-welded joints
  • 4-leg design for increased stability
  • Multiple lifting lugs for single crane erection
  • Stainless steel inner vessel and piping
  • Bolted bonnet globe valves with stainless steel bodies
  • Easily accessible relief valves
  • Durable, environmentally friendly coating for industrial standards
  • All vents are directed to the vent stack with outlet to safe area
  • Optional transmitters and actuators with EEx design
  • Safety shut off valve on liquid line is applied as standard in compliance with EN norm requirements

Notes:
1) Filling 90 % (equillibrium state at 1,013 bar)
2) Calculated for theoretical density 470 kg/m3, can vary with real composition of LNG
3) Nominal Evaporation Rate per 24 hours according to EN12213 (100 kPa and 15°C ambient temperature)
4) Tanks types VT70,VT80 are available with pressure 11 & 17 bar
5) Tanks with thermosiphon are app. 750 mm higher in sizes VT3-VT60 and 790 mm in sizes VT70,VT80
6) Design and specification are subject to change without prior notice.
