Product Description

LCO2(Liquid Carbon Dioxide) 20ft ISO Tank Container

A 20-foot ISO tank container for liquefied carbon dioxide (LCO2) is a mobile pressure vessel specifically designed for the safe and efficient transportation of low-temperature liquefied gases. Below is a detailed breakdown of its design, applications, insulation methods, characteristics, and cost advantages.

1. Design and Working Principle

The design of a 20-foot liquefied CO2 tank container is highly precise, with the primary objective of ensuring reliable storage and transport while guaranteeing absolute safety.

Standard Frame and Core Vessel: Its external frame fully complies with the ISO668 standard, matching the dimensions of a standard 20-foot shipping container. This allows for seamless integration into existing global road, rail, and sea transport systems. The core within the frame is a stainless steel/Carbon steel pressure vessel (tank), typically made from materials like 304/316L stainless steel or carbon steel with printed to resist corrosion. During the design phase, engineers use finite element modeling for stress calculation and iterative optimization to ensure the frame and support structures possess sufficient rigidity.

2. Key Components and Safety Design

Insulation System: The tank usually uses High-Vacuum Multi-Layer Insulation (MLI) technology, functioning like a large thermos flask to minimize heat ingress and maintain the low-temperature state of the liquefied CO2.

Pressure Management and Safety Devices: The tank is equipped with Safety Relief Valves that activate to release pressure in case of an abnormal overpressure event, serving as a critical safety barrier. Additionally, valves and instruments such as Vapor Phase Valves are provided for filling, discharge, and pressure control.

Purity-Oriented Design: For high-purity liquefied CO2 (e.g., food-grade or electronic-grade), the inner tank wall undergoes special mirror polishing, with a surface roughness that can be controlled to Ra ≤ 0.5μm. This significantly reduces the risk of impurity retention and gas purity degradation.

3. Primary Applications

This type of tank container is primarily used for transporting and storing low-temperature liquid carbon dioxide LCO2, with wide applications in:
Industrial and Food Sectors: Transporting food-grade liquid CO2 for carbonated beverages, food processing, and refrigeration.
Chemical and Energy Sectors: Transporting industrial-grade liquid CO2 for welding, fire suppression, as a feedstock in chemical production, and within the Carbon Capture, Utilization, and Storage (CCUS) chain for moving captured CO2.

4. Insulation Technology and Temperature Management

Maintaining the low-temperature liquid state of CO2 is the core task, achieved primarily through advanced insulation technology and, if necessary, supplementary refrigeration systems.
Primary Insulation Method: The widely adopted method is High-Vacuum Multi-Layer Insulation. By creating a high vacuum within the tank's annular space and wrapping it with multiple layers of reflective material, heat transfer is effectively suppressed. Using this method, the container can achieve a static holding time (or lossless storage time) of over 90 days, meaning the temperature rise and boil-off gas (BOG) generation are minimal for nearly three months.
Auxiliary Temperature Control Systems: For shipments with strict temperature requirements, some tank containers may feature more complex, intelligent systems. For instance, they might integrate refrigeration compressor units and coil channels that circulate a coolant to actively refrigerate or heat the tank, adapting to complex transport conditions.

5. Performance and Safety Characteristics

High Safety: As a pressure vessel, it is subject to stringent international standards throughout its design, material selection, manufacturing, and inspection phases. A typical 20-foot T75-type liquefied CO2 tank container often has a working pressure of 1.8 MPa to 2.2 MPa and a design temperature as low as -196°C, ensuring transport safety.
Excellent Thermal Insulation Performance: Thanks to high-vacuum multilayer insulation, the evaporation loss of liquefied CO2 during long-distance transport is extremely low.
Guaranteed Medium Purity: The internal mirror polish and dedicated loading/unloading systems effectively maintain the quality of high-purity liquefied CO2.
Flexibility and Convenience: Its standardized external dimensions allow it to be quickly transferred between various modes of transport, just like a standard container, enabling efficient "door-to-door" logistics.

6. Transport Cost Advantages

Using 20ft tank containers for liquefied CO2 transport offers significant economic benefits:
Increased Shipment Volume: A single 20ft tank container can have a volume of over 24 cubic meters, offering higher loading efficiency compared to traditional methods.
Reduced Packaging Costs: Compared to disposable cylinders or drums, it eliminates the cost of purchasing and disposing of these packages.
Reduced Cargo Loss: The superior insulation performance results in lower evaporation losses of the medium during transit.
Simplified Logistics Operations: As an integrated package, the tank container eliminates the labor-intensive and time-consuming process of handling numerous small cylinders, saving manpower and time. The convenience of intermodal transport further reduces logistical complexity and cost.

7. International Standards and Certifications

As it involves the cross-border transport of dangerous goods, this tank container must comply with strict international regulations, primarily including:
Design and Manufacturing Standards: The frame adheres to container standards like ISO 668 and ISO 1496-1; the pressure vessel part must conform to standards such as the ASME Boiler and Pressure Vessel Code (BPVC).
Transport Regulations: Must comply with the International Maritime, and get the sole ID from china classification society(CCS) 
Dangerous Goods (IMDG) Code, the European ADR/RID agreements for road/rail transport, and others.
Target Market Certification: Access to specific national markets may require local certifications. For example, tank containers exported to Japan need strict approval from the Japanese High-Pressure Gas Safety Institute (KHK).
