【Haichuan Project Updates】The supporting gas pipeline of Sinochem has officially begun supplying gas to Sinochem Refining and Chemicals
Thread Content
With an annual designed transport capacity of 650 million cubic meters, the main pipeline of the gas transmission project supporting Sinochem Refining and Chemicals has been put into operation! At 16:18 on May 29th, as the outlet valve at Sinopec Donghai Island Station was opened, the pipeline connecting to the Zhongke refining and chemical complex began to supply gas to this project. The total length of this pipeline is 75.5 kilometers, with an annual design capacity of 1.8 billion cubic meters. It is the longest natural gas pipeline drilled through land to date, at 4,060 meters in length; after overcoming numerous difficulties, the construction team was finally able to put it into operation. Recently, good news has been coming in steadily from Sinochem Refining & Chemicals in Zhanjiang. The accompanying gas pipeline has been successfully connected to supply gas to this facility, which not only ensures an adequate supply of gas for its operations but also lays the foundation for developing the Sinopec natural gas market in western Guangdong. This is of great significance for promoting coordinated regional development in that area, improving the level of energy services, and ensuring the sustainable, stable, and healthy growth of the local economy!
Why do you say refining companies need so much LNG? Is hydrogen produced from natural gas?
I was also thinking of asking you – isn’t it about oil refining? ? ? 、、 Is it used in combustion heating furnaces? ? Isn’t hydrogen production always said to be done using coal?
To find out about the projects of Zhongke, generally, in refining and chemical production, LNG and LPG are produced as by-products. Some production facilities use LNG as a raw material; for example, CNOOC Hainan Petrochemical uses LNG as a feedstock for hydrogen production.
CNOOC Hainan Petrochemical uses LNG as the raw material for hydrogen production – this is likely the same approach. The CNOOC project was probably designed using Sinopec’s technology, with Sinopec handling the construction work
However, **it is stipulated that LNG cannot be used as a raw material for chemical industries outside of specific areas. Hainan Petrochemical uses LNG to produce hydrogen because the natural gas extracted by CNOOC from the Yinggehai oil and gas field in the South China Sea is of poor quality and not suitable for use as LNG fuel.
Oh. I see, so that means it’s difficult to purify it at the moment
It could also be a raw material for syngas plants, with syngas serving as a raw material for acrylate esters. In practice, however, using a coal-based hydrogen production plant to produce hydrogen, CO, and syngas is the most suitable approach.
