Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Have a happy weekend! ********************************************* At 17:11 on May 12, 2022, the Shenwei Pipeline Operation Company began carrying out the task of transporting 160,000 tons of raw coal from Shenmu to Pucheng, in accordance with the production scheduling orders. At 14:25 on May 21, the task of transporting 160,000 tons of raw coal from Shenmu to Pucheng was successfully completed, with a total duration of 213 hours and 14 minutes. Thus, through the joint efforts of all employees at Shenwei Pipeline Transportation Company, the test of operating the Shenmu-Pucheng pipeline line with slurry was successfully completed; the equipment is functioning properly and operates stably. In this operation, 160,000 tons of raw coal were transported over a distance of 590 kilometers, with a total volume of slurry transported amounting to 217,905 cubic meters. The entire process involved coordinated operation of various systems such as coal to slurry conversion, pumping, dewatering, storage, and transportation; all these systems were interconnected and operated strictly in accordance with the established plans and procedures. During operation, the company’s dispatch team adjusts the operating conditions based on actual circumstances to ensure the long-term stable operation of the system. During this period, all operational tasks were carried out independently by Shenwei Pipeline Operation Company, laying a solid foundation for the continuous operation during the subsequent trial production phase. The success of operating the entire line at full capacity with slurry is of great significance; it not only indicates that the equipment in the entire production system is operating at full load, but it also represents a coal slurry transport operation that involved transporting the largest volume of slurry in a single instance, over the longest continuous period of time, with all production systems in use.
At 6:25 a.m. on May 28, 2022, the stream of coal slurry pumped from the slurry storage tank pump at Pucheng Station, operated by the Production and Operation Company, flowed into Storage Tank No. 1 at Huaxian Station. When the coal slurry entered the measuring cylinder through the sampling port, warm applause erupted at that location to celebrate this moment of great historical significance. It is understood that the total slurry transfer volume during this operation with slurry will reach 3344.8 m3. This batch of coal slurry is primarily used for the slurry-testing phase of the concentration system at the Hua County station operated by the company, and it is also intended as coal for chemical gasification; it is planned to be delivered to Shaanxi Chemical Industry Company. It is worth noting that the commissioning of the thickening system with slurry this time will involve the use of the \"three-peak particle size distribution\" technique for the first time, a technology that is unique in China.
At 16:00 on June 2, 2022, upon the order to \"start the slurry transfer pump and transfer the slurry to Shaanxi Chemical Company,\" 130.57 m3 of high-concentration water-coal slurry was transported via a direct pipeline to the large coal slurry tank at Shaanxi Chemical Company’s gasification facility. At 17:48, good news came in from the sampling point within the Shaanxi Chemical Company’s premises: Shenwei Pipeline Transportation Company succeeded in transporting high-concentration water-coal slurry to the Shaanxi Chemical Company. This marked the first time in China that high-concentration water-coal slurry with a concentration of 53% was upgraded to 65% through pipeline transportation, thereby enabling its industrial application. Starting from May 28, under the coordination of Shenwei Pipeline Transportation Company, with the full cooperation of the company’s relevant departments and design units, 130.57 m3 of high-concentration water-coal slurry of qualified quality was successfully produced through 4 days of intensive testing, using the coal slurry transported from Shenmu to Huaxian Station. The distance between the Huaxian station of Shenwei Pipeline Transportation Company and the large coal slurry tank for gasification at Shaanxi Chemical Industry Company is approximately 800 meters, with the coal slurry concentration at 65.8%. This represents an important milestone in the direct supply of high-quality gasified coal slurry products from Shenwei Pipeline Transportation Company to Shaanxi Chemical Industry Company.
