Green Energy helps "double carbon" targets my country's gas storage facilities construction to accelerate comprehensively

On September 22, the No. 10 storage tank of the No. 10 storage tank of the first phase of China Sea Yanyan Green Port undertaken by China Construction Power Construction Co., Ltd. successfully completed the raising task, marking the basically completed the main structure of the storage tank, laying the foundation for the project on time. After completion, it will become the largest LNG (liquefied natural gas) reserve base in China.

Storage of natural gas is an effective way to solve demand fluctuations and ensure the safety of energy supply. For my country, it is of great significance to accelerate the construction of gas storage facilities at this stage. The construction of gas storage libraries is an indispensable link to a certain extent. In recent years, strengthening the construction of natural gas storage facilities has been regarded as an important task to ensure the safety of my country's energy safety. Especially after the "gas shortage" in the winter of 2017, my country's gas storage facilities started to speed up the construction.

CNOOC Yancheng Green Port project is invested and constructed by CNOOC Jiangsu Natural Gas Co., Ltd. It is a key planning project for the construction of the national natural gas production supply and storage system and interconnection. The largest LNG receiving station project. The first phase of the 4 LNG storage tank and the first -phase expansion project of the first phase of the project of the first phase of the project is 270,000 cubic meters of LNG storage tanks in the world. Construction tasks of appendix facilities. After the tank on the 10th was successfully raised, all the storage tanks of the entire base were completed, and the main structure was basically completed.

The LNG storage tank is a cylinder structure of about 100 meters and a tank height of 65.7 meters. The top is a "hat" of about 14 meters high. This hemispherical "hat" is the dome of the smooth rising. The diameter of the dome is about 90 meters, the height is about 13.814 meters, and the weight is 1200 tons. The area is equivalent to a large football field. The raising of the dome is to use the fan system to raise the dome to a height of more than 60 meters. It takes 500,000 cubic meters of air to rise to the dome, which is equivalent to filling 700 million football in it. This time, the construction process with the highest technical difficulty and the highest safety coefficient during the construction process. In the process of raising the top, the project team accurately controls the safety and stability of the gas pressure littering through the four major systems of the four major systems through balanced orientation, tank sealing, ascending power, and intelligent detection of the four major systems. Essence

Because the dome climb steadily along the wall of the tank body, it puts forward ultra -high requirements for the verticality of concrete in the inner wall. The China Construction Electric Power Project Team is planned in advance to do a good job of process control. Each layer of wall construction must be re -measured and adjusted at each template for not less than three times to ensure the "zero error". The number of vertical measurements of the wall is close to 4,000 times. During the concrete pouring process, special persons are arranged to monitor real -time monitoring and correct them to ensure that the process does not deform. After the concrete pouring is completed need.

It is understood that when the concrete was poured in Chengtai, the project was constructed by jumping and bold innovation on this basis. In the five districts, compared with the traditional 8 districts, the construction intermittent frequency is greatly shortened. Each area is continuously poured for about 18-22 hours. At the same time, it can be continuously poured in two areas. Greatly improved the pouring efficiency of Chengtai concrete.

"Our construction is almost built, and the project can be completed and put into production a day, and the local area can be used to use clean energy one day."

As the national initial planned natural gas production supply and storage base with 30 million tons/year, CNOOC Yancheng Green Port LNG project was given "increasing the supply of natural gas in East China, supplemented the natural gas market gap in Jiangsu Province, optimized the energy structure of the Yangtze River Delta region, promoted the regional region The important role of energy security is of great significance to help my country achieve the "double carbon" goal.

According to the data, after the project is put into production as a whole, LNG's annual processing capacity can reach 6 million tons, which is equivalent to 8.5 billion cubic meters of gaseous natural gas, which can be used as a human livelihood gas for people's livelihood for about 28 months. Based on a 1 -cubic meter of natural gas generating 5 degrees, 8.5 billion cubic meters of natural gas can generate about 42.5 billion kWh. It can achieve 28.5 million tons of carbon dioxide and 232,500 tons of sulfur dioxide, which is equivalent to 60 million trees.

As a relatively clean fossil energy, natural gas is an important "bridge" to the goal of "double carbon". my country ’s natural gas consumption increases at a rate of about 10%each year. The total amount of natural gas consumption that is continuously enlarged has put forward higher requirements for preservation.

Since participating in the construction of the LNG tank project in 2011, China Construction Power has participated in 16 LNG receiving stations such as Tangshan, Tianjin, Yancheng, Zhangzhou, Guangxi and other LNG receiving stations for more than ten years. Cubic meters, the scale of the project has grown from a single can from a single can to 270,000 cubic meters of the world's largest volume. Promoting the adjustment of energy consumption structure has plays an important positive role in reducing pollution and protecting the ecological environment, and solidly and effective help to achieve the realization of my country's "double carbon" goals.
