There was a small complication when this device was transported to the factory entrance
On the morning of December 12, a lifting ceremony was held for the product separation tower, a PDH core equipment unit produced by Dongguan Juzhengyuan Technology Co., Ltd., marking the entry of this project into the full installation phase.
The product separation tower is one of the key equipment in the propane dehydrogenation project, used to separate propylene from propane. This facility is manufactured, transported, and lifted as a single unit; it has a maximum diameter of 12 meters, a height of 128 meters, and a total weight of around 3,050 tons, making it the largest of its kind in China. Its lifting is carried out using a state-of-the-art 3,600-ton hydraulic jacking device as the main lifting mechanism; the \"hydraulic synchronous jacking technology\" is employed to raise the equipment vertically, lift it higher, and position it in place. At the same time, the 1250-ton class crawler crane uses a method of moving behind the equipment to deliver it, allowing the equipment to gradually transition from a horizontal position to an upright position, thus completing the overall lifting and positioning of the equipment.
The Juzhengyuan propane dehydrogenation project for producing high-performance polypropylene is located on Lisha Island in the Shatian Port Area of Humen Port, Dongguan City. Two production units with a combined capacity of 1.2 million tons per year for the production of high-performance polypropylene from propane will be built there, with a total investment of around 10.5 billion yuan. The facility includes a production area, a tank storage area, and supporting areas, with a total land area of 984 mu. Among them, the first phase of the project, which involves the production of polypropylene via propane dehydrogenation with a capacity of 600,000 tons per year, requires an investment of around 6 billion yuan. The project covers an area of 688 mu, and it is planned to build one propane dehydrogenation unit with a capacity of 600,000 tons per year, as well as two units with a capacity of 300,000 tons each/
At the end of October 2017, the first phase of the project commenced construction; China National Chemical Third Construction Engineering Company was assigned the general contracting task for the polypropylene plant, with a contract value of 160 million yuan and a construction period of 592 days. On February 9, 2017, the Dongguan ** website published a supplementary announcement (the third one) regarding the \"Environmental Impact Assessment Report for the First Phase of Dongguan Juzhengyuan Technology Co., Ltd.’s 1.2 million tons per year propane dehydrogenation project to produce high-performance polypropylene.\" On September 21, 2016, Juzhengyuan Company held a meeting to discuss the details of the process package contract for the propane dehydrogenation project, as well as a signing ceremony for the engineering design contract, in collaboration with LUMMUS and Sinopec Ningbo Engineering Company; the total value involved was approximately 200 million yuan. This marks the entry of the project into the substantive design phase, with all construction activities proceeding step by step according to the planned schedule ； The signing of the two contracts also marks the project’s entry into a substantive phase of funding. On August 10, 2016, the project held its groundbreaking ceremony.
