The Shen-wei pipeline coal transport project is subject to the environmental protection industrial policy of the Guanzhong region, and the large gap between the transportation capacity of pipeline coal transport (10 million tons/year) and the consumption capacity of the terminal chemical plant leads to a large surplus of coal slurry. In order to ensure the safe and stable operation of coal transport pipeline and the best comprehensive benefit of coal transport pipeline, surplus coal slurry needs to be dehydrated and sold. At present, there is no engineering case of this scale in China for reference. Combining the product characteristics of coal slurry after dehydration (fine, wet and sticky) and the design experience of Shen-wei pipeline coal transport project phase I, the scheme selection and optimization design of each process system of storage and loading are carried out. At present, the surplus coal slurry application engineering storage and loading system has been running stably for 3 years, and has transported about 20 million tons of coal in total, which has created good benefits for enterprises.
