Large Volume Type-4 Tanks

CanaGas Type-4 pressure vessels (tanks) are made using a high-density polyethylene (HDPE) liner with stainless-steel port bosses. Depending on the required operating pressure, the liners are wrapped with either fibreglass in a vinyl-ester matrix or carbon fiber in an epoxy matrix.  

All CanaGas tanks are made from the same HDPE liner – 2.0 meters in diameter by 3.5 meters in length. Three of these 10,000 litre tanks will fit inside of a 40-foot intermodal shipping container or ISO frame. For rail service, four tanks are installed inside of a 53-foot shipping container or ISO frame.  Once the piping and instrumentation is installed, the void space is completely filled with a fire-retardant expanded polyurethane foam. This provides a high level of insulation and protection from a potential fire from outside. 

CanaGas offers four operating pressures in its gaseous fluid transport systems: 

7.5 Bar fibreglass tanks for the transport of methanol, DME, ammonia, contaminated water, diluent (C5+) and silica tetrafluoride, a very corrosive fluid.

  • 17 tonnes per 40-foot container.
    No refrigeration required.

7.5 Bar fibreglass tanks in a high-impact resistant container for the safe transport of heavy oil.

  • 230 bbls of heavy oil in a 53-foot enhanced container (For rail transport).
    The oil is kept warm for ease of discharge.

15 Bar fibreglass tanks for the transport of propane and LPG.

  • 16 and 17 tonnes per 40-foot container, respectively.
    No refrigeration required.

40 Bar carbon fiber tanks for the transport of ethylene, ethane, and liquid CO2.

  • 17 and 19 tonnes per 40-foot container, respectively.
    No refrigeration required for either substance.

100 Bar carbon fiber tanks for the transport of pressurized liquefied natural gas (P-LNG).

  • At -50 C, 10 tonnes per 40-foot container.
    At -70 C, 14 tonnes per 40-foot container.
