【Ten Years of Great Progress in Chemical Technology】From 2012 to 2023, Tianjin Petrochemical will carry out the ALL-PE industrialization demonstration transformation project for polyethylene production facilities

The ALL-PE industrial demonstration and transformation project for the polyethylene plant in Tianjin Petrochemical’s olefins division is a polyethylene production technology developed jointly by Sinopec Tianjin Branch, Sinopec Engineering Construction Co., Ltd., Zhejiang University, Shanghai Research Institute of Chemical Industry Co., Ltd., and Beijing Research Institute of Chemical Technology. Characterized by a shorter production process, advanced technology, and high innovation level, this technology has given rise to 23 Chinese invention patents, of which 15 have been approved; it is thus at the international leading level.

Recently, the Olefins Department of Tianjin Petrochemical organized a review meeting for the \"Preliminary Design (Draft) of the ALL-PE Industrialization Demonstration Transformation Project for Polyethylene Plants.\" Wang Qingjiang, the deputy manager, Liang Xiuwen, an expert in chemical processes, Du Huanjun, the assistant manager, along with technical professionals from the Technical Quality Department, Production Department, Equipment Department, Safety and Environmental Protection Department, and the Polyethylene Workshop, attended this design review. In addition, the heads of the Development Planning Department, Electrical and Instrumentation Department’s Third Area, and the Laboratory and Metrology Center were also invited to participate in the meeting. The basic design review meeting conducted a comprehensive assessment based on the principles of foresight, scientific rigor, and practicality, covering various specialties such as general layout, architecture, structure, processes, piping, mechanical and electrical equipment, pumps, instrumentation, electricity, telecommunications, analysis and testing, fire protection, safety, environmental protection, energy conservation, and seismic resistance. A total of 132 issues were identified during the meeting, and the participants offered suggestions for modifications; the minutes of this professional meeting have been submitted to the company’s development planning department. This review session serves as the first checkpoint for the project’s basic design, laying a solid design foundation for the ALL-PE industrialization demonstration transformation.

On March 16, 2022, the civil engineering work for Sinopec’s Tianjin Nangang ethylene project commenced, marking the official start of construction for this cluster project, which has a total investment of 60.3 billion yuan. The Nangang ethylene project is led by an ethylene plant with an annual production capacity of 1.2 million tons. Using naphtha and cracking tail oil supplied by the Tianjin Petrochemical refinery, as well as ethane/liquefied gas separated from LNG by the planned Nangang LNG separation unit, the project develops 12 advanced new material production facilities based on ethylene, including those for ultra-high molecular weight polymers, α-olefins, ALL-PE, ABS, POE, HDPE, and others. It is understood that the Nangang ethylene project is expected to be completed in 2023, aiming to become world-leading, fill a gap in China’s market, and replace imported products.
