Shaanxi Chemical Construction successfully hoisted the world's tallest and largest separation tower

The tower stands tall, and Fota races high
.
On November 21, in the Zhongjing Petrochemical Science and Technology Park in Fuqing Jiangyin, Fujian Province, the Zhongjing Petrochemical Project with an annual output of 1 million tons of propane dehydrogenation (phase II) undertaken by Shaanxi Chemical Construction successfully completed the lifting task of the world's highest and largest propane propylene separation tower, once again demonstrating the "hard power"
of Shaanxi Chemical Construction.

The propane propylene separation tower is the core equipment of the propane dehydrogenation project, with a height of 138 meters, a weight of 2,700 tons and a volume of 11,000 cubic meters
.
Combined with the actual situation on site, Shaanxi Chemical Construction adopts its own world's first 3200-ton crawler crane that can be disassembled into 1600 tons of models, and adopts the method of on-site group pair and sectional lifting for installation
.

On November 20, the head of the propane propylene separation tower was equipped with lifting conditions, ushering in the "last hoist"
at an altitude of 100 meters of the tower.
Since the lifting height reached 138 meters, the high-altitude strong wind brought challenges to hoisting, grouping, welding, etc.
, which became the biggest difficulty of this lifting operation
.
The company's project hoisting team adopted methods such as adjusting the length of the hoisting wire rope to ensure the horizontality of the head, inverting the chain to fix the attached tower pipeline, and installing a temporary platform to ensure the smooth progress of the head hoisting
.
At 8:20 a.
m.
, with the order of the chief commander of hoisting, with the help of the 3,200-ton crawler crane, the head of the separation tower and the tower body completed a beautiful "fit"
at an altitude of 100 meters.

It is reported that Zhongjing Petrochemical's annual output of 1 million tons of propane dehydrogenation project has a total investment of 4 billion yuan, introducing the United States Rums propane dehydrogenation to propylene process technology to produce high-purity propylene raw materials to meet the downstream needs
of the park.

In recent years, with the large-scale, large-scale and modular construction needs of equipment in the petrochemical industry, the advantages of large-scale equipment ground group and overall lifting have become prominent
.
Shaanxi Chemical Construction to undertake the construction of petrochemical engineering construction, in order to further meet the construction needs, improve the market competitiveness of enterprises, has 3200 tons, 1600 tons, 800 tons, 600 tons, 450 tons and other different tons of lifting equipment, at present, Shaanxi chemical construction machinery and equipment strength is strong, large-scale equipment lifting capacity leaps to the forefront of the domestic petrochemical construction industry, can meet dozens of large-scale petroleum, chemical, energy engineering construction tasks at the same time, for 11 consecutive years "China's top ten lifting enterprises"
