Liquid CO2 Tank Semi Trailer Cryogenic Carbon Dioxide Storage Road Tanker Truck

Liquid CO2 Tank Semi Trailer Cryogenic Carbon Dioxide Storage Road Tanker Truck

The cryogenic liquid carbon dioxide transport tank truck (LCO ₂ cryogenic tank semi-trailer) is a special equipment for mobile pressure vessels, specially designed for the road transportation of liquid carbon dioxide. It adopts a double-layer vacuum insulation tank structure, the inner tank is made of special steel for low-temperature-resistant pressure vessels, the outer layer is protective shell, and the interlayer is high-vacuum multi-layer heat insulation, maintaining the working conditions of-20 ~-30 °C and 2.0 ~ 2.2 MPa in the tank, Restrain liquid CO ₂ vaporization loss. The whole set of equipment integrates pressure monitoring, liquid level display, multi-stage safety pressure relief, emergency cut-off valve, loading and unloading pipeline, braking and protection system, GB/ASME and other global mainstream pressure vessel standards, widely used in industrial gas distribution, food and beverage, Long-distance land transfer of LCO ₂ in industries such as dry ice production. Volume, shaft type, export certification, and instrument configuration can be customized according to customer conditions, and support third-party supervision and a complete set of testing of factory water pressure, air tightness, and vacuum performance.

✅ Inner vessel with cryogenic pressure vessel steel, robotic automatic welding, 100% NDT inspection for welds.

✅ Multi safety protection: safety valve, rupture disc, emergency shut-off valve for overpressure protection.

✅ Integrated pressure, liquid level & temperature ports, optional IoT remote monitoring module.

✅ Lightweight optimized design to reduce tare weight and increase payload.

✅ Pre-installed loading/unloading piping, valves, static protection, anti-collision and hazard marking.

✅ Modular valve cabinet for centralized operation and easy maintenance.

✅ Fast connection with tractor head, suitable for long-distance hazardous goods transport.

1.Excellent insulation performance, daily boil-off ≤0.5% under standard condition, reduce LCO₂ loss and cut operation cost.

2.Full inspection for pressure vessel: raw material test, weld RT/UT, hydrostatic test, air tightness and vacuum test.

3.Famous brand valves, cryogenic resistance, low leakage rate and long fatigue life.

4.FEA finite element stress simulation, optimized for bumpy road and thermal cycling condition.

5.Complete safety interlock, multi-protection for overpressure & overfill, reduce hazardous transport risk.

1.Bulk LCO₂ distribution for industrial gas companies (beverage, welding, cleaning shielding).

2.CO₂ land transport for CCUS carbon capture projects.

3.CO₂ EOR enhanced oil recovery for oilfield.

4.Raw LCO₂ supply for dry ice factories.

5.Low-temperature raw material for chemical, pharmaceutical & food industry.

6.Feed transport for large cold chain and fire suppression system.

Operation Notes:

1.Operators must hold valid certificate and receive cryogenic hazardous material safety training.

2.Overfilling forbidden; filling volume ≤95% tank capacity.

3.Monitor tank pressure continuously during transport, no overpressure operation.

4.Loading/unloading zone must be well ventilated and away from fire & heat source.

5.Wear anti-freezing PPE to prevent cryogenic frostbite.

6.Periodic calibration for safety valve, pressure gauge and level gauge; regular statutory inspection required.

7.Do not operate trailer when vacuum of tank jacket decays beyond limit.

8.Avoid closed low-lying area; CO₂ is heavier than air and may cause suffocation.

Standard Packaging Flow:

1.Blind plates or plugs are installed at tank pipeline interfaces (liquid phase ports, gas phase ports, pressurization ports) to prevent foreign objects from entering and collision damage during transportation.

2.Blind plates or plugs are installed at tank pipeline interfaces (liquid phase ports, gas phase ports, pressurization ports) to prevent foreign objects from entering and collision damage during transportation.

3.The outer surface is covered with PE protective film to prevent salt spray by sea and scratches by land transportation.

4.On-board documents: Product qualification certificate, pressure vessel supervision and inspection certificate, certificate, instruction manual are packed into waterproof file bag and fixed in the cab.

[Precautions during transportation]

Transport vehicles: Special vehicles or special low-flatbed transport vehicles with dangerous goods transport qualifications must be used.

Fixing requirements: Welded limit blocks or high-strength binding belts are used for double fixing between the tank car chassis and the transport car platform to prevent displacement on the way.

Dangerous goods label: UN 2187 (liquid carbon dioxide, refrigerated liquid) dangerous goods label and diamond mark are hung at the rear of the car.

Avoid exposure to the sun and high temperature: In case of high temperature weather during transportation, the pressure in the tank may naturally increase. Pay attention to observe the pressure gauge, and relieve a small amount of pressure through the gas phase valve if necessary.

Inspection at the destination: Before unloading, check whether the tank body has collision deformation, whether the blind plate of the pipeline interface is intact, and whether the pressure gauge reading is within the normal range.
