On April 8, the installation of the internals of the last tower of Yantai Wanhua ethylene plant, the water stripping tower, which was constructed by Shijian Company of Refining and Chemical Engineering Group, was successfully completed.
Another important node has been achieved
.
A total of 18 tower internals need to be installed in this project.
The installation procedures are complicated and the process requirements are strict.
Since the start of construction in July 2019, the construction personnel have overcome the severe heat and cold weather successively, and have experienced two periods and the construction period affected by the epidemic.
Combined with the site It has innovated a variety of construction methods, especially when the internal parts manufacturers are slow to rectify and deal with problems, the construction personnel strive to take the initiative in their work, help the owners and manufacturers to rectify the problems, the construction progress is accelerated and many bright spots have been created
.
The tallest, heaviest, and largest diameter propylene distillation column tray is a Honeywell product from the United States.
It is not only precise in manufacture, but also has stricter quality requirements and is difficult to install.
Its cylinder diameter is 8.
5 meters, its height is 114.
3 meters, and the weight of the equipment is 1460 ton, the tower internals have a total of 215 floors.
The participating team made progress despite the difficulties.
The installation of 1 floor in the first 3 days was accelerated to 3 floors in two days and 2 floors in one day.
Finally, 8 working surfaces were launched, and the installation was 30 ahead of schedule.
After the completion of the day, the owner's supervisor and leaders highly praised the spirit of Shijian employees who are particularly able to fight in the face of difficulties, have special methods, and can win the battle at critical moments.
The internal parts of the alkaline washing tower are imported materials, and the technical drawings for installation in English have brought great inconvenience.
The installation quality inspection of the internal parts of the tower implements the technical requirements of FMC manufacturers and does not implement domestic standards, which poses a greater challenge to the operators.
.
Ethylene rectification tower 61C1440 is the second tallest tower, with a tower height of 90.
7 meters, a diameter of 5 meters, a net weight of 420 tons, and a tray of 129 layers.
The data of the tray was unqualified, and the manufacturer recognized and responded to the processing, and the processing was suspended for more than a month
.
Due to the windy winter in the Yantai area, if the tray installation is delayed, it will inevitably affect the construction period of the entire installation
.
