Thread Content

On April 2, the second public announcement regarding the environmental impact assessment of the raw material sharing project between Dagang Petrochemical and Tianjin Petrochemical’s Nangang ethylene plant was released. Project Name: Inter-supply Project of Ethylene Raw Materials between Dagang Petrochemical and Sinopec Tianjin Petrochemical Nangang Plant. Constructor: Dagang Petrochemical Branch of China National Petroleum Corporation. Nature of the project: Renovation and expansion. Location: From CNPC Dagang Petrochemical Company to Sinopec Tianjin Petrochemical Nangang Ethylene Plant, Binhai New Area, Tianjin. Construction contents: This project involves the installation of 1 new full-range naphtha transfer pump, 1 light naphtha transfer pump, and 1 liquefied gas transfer pump ； One light naphtha export pipeline and one full-range naphtha export pipeline will be constructed. The light naphtha pipeline and the full-range naphtha pipeline are both laid from the inlet and outlet pumps at Dagang Petrochemical Station to the boundary of Nangang Ethylene Plant ； A new liquefied gas pipeline has been installed within the station, with the liquefied gas being transported by pumps to the boundary of Dagang Petrochemical. On April 2, the second public announcement regarding the environmental impact assessment for the new interconnection pipeline project between Nangang Ethylene and Dagang Petrochemical Company was released. Project Name: Project for Adding the Nangang Ethylene Plant to the Interconnection Pipeline Network of Dagang Petrochemical Company. Constructor: Tianjin Branch of Sinopec Corporation. Nature of Construction: Renovation and expansion. Location: The project is located in the Binhai New Area of Tianjin, connecting the Nangang Ethylene Plant of Tianjin Petrochemical to Dagang Petrochemical Company of CNPC. Construction details: Utilizing the existing public utility ducts in the park, one DN80 gas ethylene pipeline will be constructed to transport ethylene from Nangang Ethylene Plant to Dagang Petrochemical Plant, and one DN150 liquefied petroleum gas pipeline will be built to transport liquefied petroleum gas from Dagang Petrochemical Plant to Nangang Ethylene Plant. Both pipelines share the same route, running from 1 meter outside the west boundary wall of Nangang Ethylene Plant to 1 meter outside the east boundary wall of Dagang Petrochemical Plant; the length of each pipeline is approximately 7.15 km. Upon completion of this project, the designed transportation capacity for gaseous ethylene will be 8,500 tons per year, while that for liquefied petroleum gas will be 100,000 tons per year.
