Carbon Dioxide Storage Tank
1 Overview
The low-temperature liquid carbon dioxide storage tank is a double-walled container consisting of an inner and an outer vessel. It features a vacuum powder insulation design and is available in both vertical and horizontal configurations. The inner vessel is made of 16MnDR material, while the outer vessel material can be selected as Q235-B or 16MnR based on the user's location. The interlayer between the inner and outer vessels is filled with insulating material, pearl sand, and then evacuated. (Available in both vertical and horizontal types)
2 Uses
Storage: Liquid Carbon Dioxide (LCO2)
3 Insulation Performance
Insulation materials are filled with pearlescent sand under heat conditions and then vacuumed. The standard vacuum level after the sandwich is sealed is:
Effective Volume: ≤ 10m³ with vacuum ≤ 2Pa, 10m³ to ≤ 50m³ with vacuum ≤ 3Pa, and > 50m³ to ≤ 100m³ with vacuum ≤ 5Pa. Achieved through exquisite technology, unique filling process, and quality assurance commitment, for the best thermal insulation effect.
4 Security Technical Features
The low-temperature liquid carbon dioxide storage tank utilizes a "combined, safety system valve" that employs two safety valves operating simultaneously. During regular safety valve inspections, one side can be closed while the other continues to function, ensuring the safe operation of the tank.
5 Operating Systems
The storage tank container is equipped with a pressure gauge, a differential pressure liquid level gauge, and a liquid level reference chart, allowing for real-time monitoring of the container's storage volume and pressure changes, facilitating operations during filling and draining.
6 Inspection System
The tank's lower section is equipped with a dedicated vacuum detection system, vacuum gauges, and vacuum valves. The interlayer vacuum level can be regularly or immediately checked using a vacuum gauge to ensure the tank operates safely.

Liquid Oxygen Storage Tank
Overview
This series of low-temperature storage tanks are double-layer fixed vacuum powder insulating tanks (vessels). The inner shell is made of stainless steel (with 16MnDR for CO2 tanks), and the outer shell is made of Q235B or 16MnR. The surface anti-corrosion coating is applied using sandblasting, sweeping, and spraying techniques, and a two-component rapid curing liquid paint is used as well.
Application Range and Features
Primarily used for low-temperature storage of liquid oxygen, nitrogen, argon, and carbon dioxide, etc. 1 cubic meter of liquid can replace 130 gas cylinders. It can replace daily transportation of gas cylinders, saving a significant amount of labor and material resources. Widely used in industries with high gas consumption such as the gas industry, hospitals, and metal smelting, it is the best product for centralized gas supply. It features a long service life, compact structure, small land occupation, centralized control, and easy operation.

LNG storage tanks are essential storage containers for LNG fueling stations, an indispensable component of such stations. As a professional in the LNG industry, do you really understand them? Let's delve into them in detail below:
1. Packaging Style
LNG tanks typically come in vertical and horizontal types. Vertical tanks have the advantage of occupying less land, are convenient to use, and reduce the power consumption of submersible pumps due to the gravitational difference, saving electricity. However, vertical tanks usually exceed 10 meters, which can cause fear among nearby residents, so they are not suitable for urban areas. Horizontal tanks are the most commonly used type currently. Their drawback is that they require more land. Additionally, there are safety distance requirements between the storage tanks and surrounding structures and facilities both within and outside the station, which according to GB50156, increases the design complexity.
2. Insulation Type
Common insulating forms for LNG tanks include high vacuum multilayer wrapping insulation and pearl sand powder insulation. The latter is more common in practice due to its lower cost.
3. Materials
The container is made of high-quality Austenitic stainless steel 0Cr18Ni9 sheet or imported 304 sheet; the outer container is made of high-quality carbon steel Q345R plate.
4. Safety Protection System
The safety protection system consists of tank accessories, including: pressure gauges, level indicators, fully enclosed safety valves with one in use and one in reserve at the root, overflow ports, and bursting disks.
5. Filling Form
The LNG storage tanks have two methods: filling from the top and bottom. Top filling can液化 the BOG gas inside the tank with cold liquid. Both methods can be used, and the choice depends on the on-site situation during the unloading process. It's complex and can't be explained in a few sentences.

6Level Conversion
LNG液位换算质量容积及质量需要按照储罐厂家提供的数据，结合液厂的气质报告数据综合确定。
7Technical Requirements
General technical agreements require the design pressure of LNG tanks.0.8MPA, designed for temperatures down to -196°C, with a daily evaporation rate of less than or equal to 0.20%. The actual working pressure of the tank is generally less than 0..8MPA's, the operating temperature is generally determined by the liquid's quality, around -100°F.
