In July 2005, the multi-nozzle opposed coal-water slurry gasification technology industrial demonstration plant and its supporting project were successfully fed once at Yankuang Guotai Chemical Co., Ltd., and the entire process flow was completed at one time. The industrialization was successfully achieved and the production was completed in the same year. After more than two years of industrial operation, it showed good performance and advanced process indicators. Compared with similar foreign technologies, this technology has the advantages of flexible operation, advanced technology indicators and stable system operation. It is especially suitable for large-scale (more than 10,000 tons of coal per day) gasification equipment, reasonable investment scale, and low patent licensing fees. This laid the foundation for the application of large-scale coal gasification technology in China. Cathay Pacific's demonstration project won the 2007 National Quality Engineering Gold Medal on January 5 this year.
The successful operation of the demonstration project marks that the technology has matured and has the strength to compete with similar foreign technologies. It has been recognized by more and more users. It has successively been with Shandong Hualu Hengsheng Chemical Co., Ltd. and Shenhua Ningmei Group. The company, Ningbo Wanhua Polyurethane Co., Ltd. and other 12 companies have applied for a total of 30 gasifiers (including spare furnaces), and the designed daily processing coal volume has reached more than 30,000 tons.
It is understood that many companies from the United States, Canada, India and other countries also have a keen interest in the technology, intends to use the technology to build large coal, petroleum coke gasification devices.
Synthetic Cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.95-3.01g/cm3, melting point about 1000°C, specific heat 1.056j/g°C at 18-100°C. It`s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800°C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
Uses:
It`s mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for Resin and rubber-boned Abrasive wheels.
