Construction of new units for Hunan Petrochemical’s ethylene refining and integration project begins

Thread Content

On December 16, the groundbreaking ceremony for the new facilities of the Hunan Petrochemical Ethylene Refining and Chemical Integration project, which was constructed by Sihua Jian Zhongnan Company, was successfully held. As a key component of this integrated project, the total construction period is 407 days; the main construction tasks include the installation of one 550,000-ton/year light hydrocarbon recovery unit, two semi-open, unattended compressor buildings, as well as supporting facilities such as substations and combined site cabinet rooms. Among them, the light hydrocarbon recovery unit, which will be the first to start operations, covers an area of about 17 mu and utilizes an advanced shallow cryogenic oil absorption process; it is designed for the centralized processing and recovery of light hydrocarbon resources from refineries, with mechanical completion scheduled for January 15, 2027. Once operational, this facility will significantly enhance Hunan Petrochemical’s ability to supply ethylene raw materials domestically as well as its efficiency in hydrogen recovery. It not only serves as an important link in completing the integrated industrial chain that spans crude oil processing, refining, and chemical manufacturing, but it also creates favorable conditions for the second phase of capacity expansion of Hunan Petrochemical’s 8 million tons per year atmospheric and vacuum distillation units. This, in turn, provides solid support for the development of the petrochemical industry in Central China toward greater scale, a more complete industrial chain, and improved efficiency.
