Progress in Lignite Upgrading 2011

Thread Content

Name of the facility, location of the project, time of construction and commissioning, selected processing technology, production capacity, total investment, product profile, advantages and disadvantages, current progress (as of the end of 2010): Shenhua Hailar – construction began in 2009; tubular pneumatic drying and shaping process with a capacity of 1 million tons per year, 8 shaping machines. The product is used as thermal coal and is shipped to the south via Jinzhou Port. The drying process poses a risk of dust explosions； Large-scale formers have a low balling rate and are prone to failures. During the rehumidification testing of the finished coal, operations have been halted for maintenance due to a minor explosion in the drying tube as well as issues with the formers. It involves the Datang Huayin Dongwuqi Ejin Naoer Town Tegenzhao Coal Mine Industrial Park project in Dongwuzhumqin Banner, as well as the Datang Huayin Dongwu Lignite Drying Demonstration Facility project in Ejin Naoer Town – with a forming capacity of 300,000 tons per year, costing over 300 million LCC). By using this technology to process and upgrade lignite, solid fuels with good stability, low sulfur content, and high calorific value can be produced—low-temperature semi-coke (PMC) and its derivatives—low-temperature coal tar (PCT). It is currently in the installation phase: Phase 1 will have a capacity of 1,000 tons per day, Phase 2 will handle 5,000 tons per day, with a total of three units capable of processing 5,000 tons of coal per day. The Datang Guoneng Xilinhot plant used Guifu furnaces in 2009, each with an annual processing capacity of 500,000 tons. It is used as fuel for the Banjiao Power Plant, and for the deep processing of tar. Phase 2 is set to begin construction soon. Huadian Group uses Zemak tubular drying systems, while China Power Investment uses vibrating fluidized bed systems. Guodian Group in Chifeng, along with Shandong Tianli, uses pneumatic tubular drying systems with an annual capacity of 1 million tons; the total investment amounts to 380 million yuan (how many units?) ) Huaneng Group’s Yimin project, Xi’an Thermal Engineering Research Institute’s circulating fluidized bed system with a capacity of 5 tons per hour – in use on-site, still in the pilot stage. Dalian University of Technology and Shenmu Pingzhuang’s solid heat carrier-based low-temperature retorting technology has been in operation for a year; it is currently shut down. China National Chemical Engineering Group’s Jinxin company uses tubular drying technology, in collaboration with ZeMach, to upgrade lignite at a rate of 1 million tons per year. There are many technologies for lignite upgrading; these are just a few of the more significant ones. The information available is limited, so please feel free to make corrections and additions.
