15 000 T/A New-Process Carbon Black Project Starts Production

With the joint efforts of the contractor China Rubber Group Carbon Black Research and Design Institute and the investor Guizhou Huaneng Carbon Black Co., Ltd., the first 15 000 t/a new-process wet-granulation carbon black project in Guizhou is completed and put on stream in Guiyang Coal Gas Source Plant. The project has a total investment of RMB35.7 million.      Guizhou Huaneng Carbon Black Co., Ltd. uses the third-generation new-process oil-gas carbon black production technology developed by China Rubber Group Carbon Black Research and Design Institute. The raw material used in the project is coal tar, and coke oven gas is used as fuel to replace fuel oil. The project has the features of large single-furnace capacity, low energy consumption, high product quality and stable production process. The rate of collection can reach more than 99%. Tail gas discharged can be totally reused and the wet-granulation process can prevent environmental pollution.    Guizhou Huaneng Carbon Black Co., Ltd. is funded by the Employees’ Equity Holding Committee of Guiyang Coal Gas Source Plant, Guiyang Coal Gas Source Plant and Guizhou Aluminum Plant. No. 3 coke oven constructed in 2003 was intended to meet the peak gas consumption in Guiyang. The 15 000 t/a new-process oil-gas carbon black production line uses the surplus coal gas from No. 3 coke oven as fuel and the tar from coal gas purification as raw material and mainly produces wet-granulation carbon black, a reinforcing material used in radial tire production.
