Large-scale lifting for the ethane recovery plant in the Tienan natural gas deep treatment project of the Tarim Oil Field
Thread Content
On May 21, at the construction site of the ethane recovery plant for the in-depth natural gas treatment project in Lunnan, Tarim Oil Field, which is being built by Sichuan Oil Construction Company under CPECC, the upper section of the demethanization tower weighing 206 tons was successfully lifted in one go within less than 2 hours. This project is a key construction project for the group company, with the main tasks involving the construction of large-scale facilities for natural gas compression, ethane recovery, dehydration and mercury removal, as well as separation and metering. Among them, the demethanization tower is the heaviest vessel in the project, and it is divided into upper and lower sections. For the lifting of the upper section this time, a 900-ton crane is used for the main lifting operation, while a 650-ton crane is used to assist with the process. To ensure a foolproof lifting process, the project’s lifting team developed and simulated the movement paths of the two cranes, the weight distribution plans, as well as the assembly strategies for joining the upper and lower sections of the tower. Protective barriers were installed at the site, along with multiple supervisors to monitor wind conditions and weather in real time. With the assistance of two cranes, the tower was precisely positioned across the 8-meter-high and 9-meter-wide 3H pipe gallery.

On August 16, the Tarim Oil Field Ethane Recovery Project, located in Lunnan Industrial Park, Luntai County, Bayingolin Mongol Autonomous Prefecture, Xinjiang, covering an area of 320 mu with a total investment of 1.62 billion yuan, was successfully put into operation and began producing qualified ethane products. The successful commissioning of this project is of great significance for promoting the intensive use and in-depth transformation of superior resources, accelerating the construction of the 1.2 million-ton ethylene plant, speeding up the development of a petrochemical industry base across Xinjiang, and contributing to the high-quality economic and social development of Bayingolin Mongol Autonomous Prefecture as well as the southern regions of Xinjiang. Construction of this project began in March 2020. It features a large processing capacity and complex process technology, employing a \"propane pre-cooling + expansion mechanism cooling + dual recirculation\" process, which brings it to an internationally advanced and domestically leading level. The engineering design capacity is 10 billion cubic meters of natural gas per year, with each individual unit having a capacity of 5 billion cubic meters per year; it is one of the largest ethane recovery units of its kind in China. “The main component of natural gas is methane, followed by ethane, propane, and butane; by recovering and processing ethane, natural gas becomes cleaner. At the same time, ethane can also be used to produce ethylene, which in turn can be used to manufacture industrial products such as plastics and rubber. ”Pu Liming, director of the Process Engineering Department at the Southwest Branch of China National Petroleum Engineering Corporation, explained.
