Third, it ensures full-process safety and controllability by constructing a multi-layered safety protection system, adapting to extreme environments and high-risk conditions, and ensuring long-term stable operation of the system.
This solution is widely applicable in various fields such as energy (LNG storage and transportation, hydrogen energy industry), high-end manufacturing (semiconductor, electronics industry), scientific research (quantum computing, deep space exploration simulation), medical (MRI equipment, biological sample storage), and chemical engineering (cryogenic distillation separation). It can provide large-scale industrial cryogenic gas systems (such as 10,000-tonne cryogenic tanks) and also customize small-scale precision cryogenic equipment (such as laboratory micro-refrigeration devices), fully covering application needs of different scales and scenarios.
II. Core Architecture of the Solution: Four Core Modules Build a Full-Chain Low-Temperature System
The company's cryogenic gas equipment solution is designed with the concept of 'precise adaptation + high efficiency and energy saving + safety and reliability'. It consists of four core components: cryogenic storage module, cryogenic transportation module, gas separation and purification module, and intelligent control system. Each module can be flexibly combined according to user needs to form an integrated cryogenic gas processing system.

It consists of four core parts: cryogenic storage module, cryogenic transportation module, gas separation and purification module, and intelligent control system. Each module can be flexibly combined according to user needs to form an integrated cryogenic gas processing system.
As the core foundation of the solution, the cryogenic storage module provides customized services for full-specification cryogenic containers, tailored to different medium characteristics and storage scales. It covers various types, including small laboratory Dewars, medium-sized industrial storage tanks, and large ten-thousand-ton cryogenic storage tanks. The core technological advantages are reflected in two major aspects: ultimate insulation and structural optimization. The module adopts a double-layer vacuum insulation structure design, with the inner layer made of low-temperature embrittlement-resistant 316L stainless steel or low-temperature alloy material, and the outer layer made of high-strength Q235 steel. The middle layer is filled with high-performance perlite insulation material and vacuumized to ≤5×10⁻³Pa, effectively blocking heat conduction and radiation. This achieves an ultimate cold insulation effect with a daily evaporation rate of ≤0.5%, significantly reducing medium loss.
For large-scale industrial storage needs, such as LNG receiving stations and cryogenic raw material storage tanks in petrochemical parks, the solution adopts prestressed concrete storage tank technology, combined with precise foundation treatment and pile foundation design. This enables the construction of cryogenic storage tanks with a capacity of 55,000 tons or more, adapting to extreme low-temperature conditions such as -162°C (LNG) and -183°C (liquid oxygen). At the same time, it integrates multiple regional regulatory requirements to ensure the stability of the storage tanks under complex geological and climatic conditions. For small-scale storage needs in the fields of scientific research and healthcare, such as liquid nitrogen storage for stem cell banks and liquid helium storage for MRI equipment, high-precision constant temperature control cryogenic containers are provided, equipped with temperature monitoring and energy replenishment warning systems. This ensures that internal temperature fluctuations are controlled within ±0.5°C, safeguarding the safety and activity of the stored medium.
(II) Low-temperature transportation module: closed and safe + efficient and convenient
To address the challenges of cold insulation, high loss, and high safety risks associated with the transportation of cryogenic gas media, the solution proposes a diversified cryogenic transportation system consisting of 'vehicle-mounted, tank-type, and portable' options. The core transportation equipment adopts a skid-mounted integrated design, integrating cryogenic tanks, insulated pipelines, safety protection devices, etc. It features convenient installation and flexible mobility, enabling 'installation and transportation at the same time' and significantly reducing on-site deployment time.
In large-scale long-distance transportation scenarios, such as LNG cross-regional transportation and liquid hydrogen energy transportation, dedicated low-temperature transport tankers/ships are employed, equipped with vacuum insulation layers and high-efficiency thermal insulation materials. Combined with dynamic temperature monitoring systems, they can track the temperature and pressure changes of the medium in real-time during transportation. Additionally, built-in emergency pressure relief devices and leak prevention alarm systems are installed. In the event of abnormal pressure or leakage risks, emergency response procedures are automatically initiated to ensure transportation safety. For short-distance transfer and on-site mobile needs, such as laboratory liquid nitrogen replenishment and raw material transfer for small chemical enterprises, portable low-temperature transport Dewars are provided. They are designed with lightweight construction and equipped with shockproof and explosion-proof structures, balancing convenience and safety.
(III) Gas separation and purification module: Multi-process integration + ultra-high purity
Addressing the core demand for high-purity gases in industrial production and scientific research, the solution integrates three core processes: cryogenic distillation, cryogenic adsorption, and cryogenic condensation. These processes can be flexibly combined and utilized based on the characteristics of mixed gas components (such as boiling point differences and adsorption differences), enabling precise separation and efficient purification of complex gases. For instance, in oxygen-nitrogen separation scenarios, the boiling point difference between oxygen (-183℃) and nitrogen (-196℃) is exploited to achieve efficient separation through cryogenic distillation, resulting in an output purity of over 99.99%. In hydrogen purification scenarios, cryogenic adsorption is employed, leveraging the selective adsorption characteristics of activated carbon at low temperatures for impurities such as carbon monoxide and carbon dioxide, to extract high-purity hydrogen, meeting the raw material purification needs of the hydrogen energy industry.
The core purification equipment is made of special materials resistant to low-temperature corrosion, featuring built-in multi-layer trays and high-efficiency packings to enhance the mass transfer efficiency of gas-liquid contact. Equipped with a high-precision temperature control system, it can precisely regulate the separation temperature to ensure stable separation purity. Additionally, a pre-treatment module is integrated, which removes impurities and pollutants from the mixed gas through filtration, chemical absorption, and other methods. This prevents solid blockages in the equipment at low temperatures, ensuring a continuous and reliable purification process.
(IV) Intelligent control system: full-process visualization + precise regulation
The solution is equipped with a DCS+PLC intelligent control system, integrating high-precision sensors, data acquisition modules, and a remote monitoring platform to achieve automated control and intelligent operation and maintenance of the entire process of the cryogenic gas system. The system can monitor key parameters such as temperature, pressure, liquid level, and purity in real-time during storage, transportation, separation, and other stages. Through big data analysis, it achieves dynamic optimization and adjustment of parameters, such as automatically initiating a replenishment procedure based on the medium's liquid level and adjusting separation process parameters based on gas purity feedback.
In terms of safety and security, the system is equipped with multiple built-in interlock protection mechanisms, including an explosion-proof control cabinet (with an explosion-proof rating of Ex dIIBT4), an online leak detector, and an emergency pressure relief device. In the event of risks such as abnormal temperature, excessive pressure, or gas leakage, it immediately emits audible and visual alarms and initiates emergency shutdown, pressure relief, isolation, and other response measures to comprehensively ensure the safe operation of the system. Additionally, the system supports remote operation and maintenance as well as predictive maintenance. Through real-time data monitoring and fault warnings, potential equipment issues can be identified in advance, shortening maintenance cycles and reducing operation and maintenance costs.
