Atmospheric Storage Tank:

We offer large and medium-sized atmospheric LNG storage tanks, as well as extra-large atmospheric LNG storage tanks.

2. Important Notes

1. Cylinders must be stored in well-ventilated areas, maintaining a distance of no less than 1.5 meters from any fire or heat sources. Cylinders are strictly prohibited from being heated with fire, boiled, or left in direct sunlight. Regular inspections should be conducted for the airtightness of cylinder valves and pipeline joints, ensuring no leakage. Leaks can be checked using soap water; it is strictly forbidden to use an open flame for leak testing.

2. When lighting, always ignite the primer first, followed by opening the gas; do not reverse the sequence. There should be a person supervising during use, and they should not leave the area to prevent boiling water from overflowing and extinguishing the flame, which could lead to the escape of liquefied gas and cause an explosion. After using the gas cylinder, the valve must be tightly closed to prevent gas leakage.

3. The liquefied gas in the cylinder should not be completely exhausted; a certain residual pressure must be maintained. The residual pressure should generally be greater than 49.03 kPa (i.e., 0.5 kg/cm2, gauge pressure) to prevent air from entering the cylinder. After the liquefied petroleum gas is used up, the remaining residue inside the cylinder is also a flammable material and should not be poured out arbitrarily to prevent fires caused by the leakage and evaporation of the residue.

4. LPG cylinders are pressure vessels that require proper maintenance and regular inspection. During handling and use, prevent the cylinders from falling or being struck. Do not use metal tools to敲击 open the valve, and avoid direct sunlight exposure and prolonged exposure to rain. Cylinders are typically inspected every 2 years.

5. Although the explosive range of liquefied petroleum gas (LPG) is not very wide, its lower limit is small, making it easily ignitable upon leakage. Moreover, since LPG is heavier than air, it tends to flow downwards upon leakage in the air, accumulating in low-lying areas and posing a hidden danger of gas explosions. Therefore, in areas where gas leakage is likely, simply exchanging air through windows is insufficient; attention must also be given to proper ventilation at the lower levels.

6. Upon discovering a liquefied gas leak indoors, promptly open windows and doors for ventilation, allowing it to disperse away from any open flame. Prohibit any fire nearby. Use the product only after the fault is resolved and the distinctive odor has dissipated. Dispose of any spilled liquid on the ground by covering it with sand and soil, then remove it to a safe location. In case of a gas cylinder fire, immediately close the valve, move it to an open area outside, and extinguish the fire using dry powder extinguisher, carbon dioxide extinguisher, or by covering it with a wet sack.

7. Educate children not to tamper with gas cylinders carelessly, and users must be aware of the safety knowledge for using gas cylinders.

The rise of LNG community gasification in China

If the 1980s to 1990s were the era of China's LPG community gasification, then the first 10 to 20 years of the 21st century will be the era of China's LNG community gasification. The origin of China's LPG community gasification is in Shenzhen, Guangdong, and the origin of China's LNG community gasification should be in Zibo, Shandong. The gas source for Guangdong's LPG community gasification mainly relies on overseas imports, while the current gas source for Shandong's LNG community gasification primarily comes from the LNG production plant in Puyang, Henan, with more gas supply channels expected in the future.

Yangzhai LNG Gasification Station, Zibo City, Shandong Province

This project is the first in China to design a gasification station for unloading, storage, and gasification of liquefied natural gas. The liquefied natural gas is transported from the Zhongyuan Oilfield to the Zibo Gasification Station in低温 tankers.

The Zibo project commenced design in June 1999 and was completed in January 2000. The Zibo Gas Company began construction in January 2000, and the facility was completed in October 2000. It was initially tested with LNG and officially started supplying LNG on December 2, 2001. It is the first LNG gasification station in China and the largest in Asia, providing natural gas exclusively to industrial users with a designed capacity of 120,000 Nm3/d.

Qingdao Jinjialing LNG Community Gasification Station

The Jiajialing project commenced design in June 2000 and was completed in January 2001; Qingdao Gas Company began construction in January 2001, and the facility was built and successfully trial-operated in February 2002. It is the first civil liquefied natural gas gasification station in China, with a design capacity of 20,000 Nm3/d.

Guangdong Longchuan LNG Community Gasification Station Project

The Longchuan LNG liquefaction plant has a short design and construction period, taking less than a year from design to completion. The grand opening ceremony was held on May 23rd this year. The design capacity is 10,000 Nm3/d.

Although Longchuan Station's LNG currently comes from Puyang, Henan, the operator's gaze is fixed on Shenzhen. Once the Shenzhen LNG receiving station is completed, Longchuan will be the受益者.

The Longchuan LNG Gasification Plant project is a management general contracting project under the management of Qingdao Chemical Engineering Design Institute.

In China, currently under construction and set to be operational are LNG gasification stations in Shangqiu, Henan; Jiangyan and Shuyang, Jiangsu; Fangzi, Shandong; Suzhou, Zhejiang; Miyun, Beijing; and Bengbu, Anhui. In the planning stages are cities such as Yuyao, Zhejiang; Jiujiang, Jiangxi; Weifang, Shandong; Pingdu and Qingzhou; and Xiamen, Fujian. It is said that after completing the construction of the LNG gasification station in Longchuan, Guangdong, Shanghai Datan Energy Co., Ltd. plans to invest in and build LNG community gasification stations in cities like Yangjiang, Huide, and Shanwei in Guangdong.

The recent surge in LNG community gasification in Shandong, China, has far outpaced the LPG community gasification boom in Guangdong, and even surpassed the development pace of Japan in the 1970s. Whether it's the scale of construction, speed, organizational form, or the level of public concern and influence, it is unparalleled by the Guangdong LPG community gasification projects.
