China to achieve large scale coal slurry gasification plant
SINGAPORE Bloomberg May 18 to 19, from Jiangsu Yixing held the second multi-Nozzle extension and application of coal gasification technology seminars to upload news to China's own large scale coal slurry gasification plant , the current single-day handle 2,000 tons of coal stoves Multi Nozzle coal slurry gasification plant has been a successful run, will China's development of coal-to-olefins, natural gas, coal new coal chemical industry to provide strong technical support. This indicates that domestic multi-nozzle gas scale application of technology to realize new leap.
Large scale coal chemical industry development trend, and large scale installation of technical equipment needed to do large-scale support. Prior to the new coal gasification technology made small, the introduction of coal gasification technology has not matured, affecting the large scale domestic chemical process. Because of this, including the gasification of coal chemical industry, including large-scale equipment was identified as China's "Eleventh Five-Year" period of 16 to develop one of major technical equipment, of which 2,000 tons of coal daily processing of new coal slurry gasification technology was included in the national "Eleventh Five-Year" Plan 863 subjects.
Multi-nozzle gas from the East China University of Technology and Yanzhou Mining Group to develop, in June 2005 and October, daily processing 750 tons of coal, 1,150 tons of the demonstration plant has invested industrial operation. June 15, 2009, single-day handle 2,000 tons of coal stoves Multi Nozzle coal slurry gasification plant in Spirit Valley Chemical Co., Ltd. Jiangsu smooth feeding operation, as currently the largest capacity single oven gas CWS of devices. As of the end of April, the device runs about 280 days total, gasification zero fault stop with pressure even voted four times, the device is stable. March 18 this year, Shenhua Ningxia Coal Industry Group Co., Ltd. single-furnace coal 1960 tons daily processing of multi-Nozzle coal slurry gasification plant, are also a feeding success, access to long-term stable running. Scene two companies run data show that the gasification of carbon conversion rate is higher than 98%, the effective gas composition synthesis gas (carbon monoxide + hydrogen) up to 85%.
East China University of clean coal technology, according to Institute of locks introduced in wide, multi-nozzles gasifier large scale, the operation flexibility increases, the load of each nozzle in the economies of scale, further optimization of refractory lining usage, production run easy management, a relatively lower maintenance costs, reduce the number of gasification series, further reducing investment.
Petroleum and Chemical Industry Planning Institute president According to Gu Zongqin pointed out that large scale multi-nozzles gasifier, the more obvious advantages of various aspects, will China's development of coal-olefins, natural gas, coal new coal chemical industry to provide strong technical support. Chinese Academy of Engineering Ni recommendations to gasification-based efficient and clean use of coal should be included in the new field of energy, speed up development.
