长距离浆体管道输送的技术经济(拉迈西L.甘地)精讲.ppt

First Kunming (China) International Science Seminar and Technical Exchange Meeting, Sept 11-13, 2007 Advantages and Limitations优点和限制 Pipelines are buried and out of sight-管道埋在地下，看不到 No noise or dust pollution-无噪音或灰尘污染 Is not affected by weather conditions-不受气候条件的影响 Does not give rise to traffic problems-不会导致交通堵塞 No traffic accidents-不会造成交通事故 Lower environmental impact-对周围环境的影响较低 Operating costs are lower-运行成本较低 Less subject to inflation-不易受通货膨胀的影响 Unit transportation costs are generally lower-单位运输成本通常较低 First Kunming (China) International Science Seminar and Technical Exchange Meeting, Sept 11-13, 2007 Advantages and Limitations优点和限制 Pipelines have limited turn down capacity-管道输送减少量受限制 Delivery points cannot be easily changed-不能轻易改变矿浆排出点 Material must be finely ground-材料必须磨细 When slurry preparation is specifically done for pipeline transportation, the cost of slurry preparation and dewatering becomes part of transportation cost -当用于管道输送的矿浆制备好后，矿浆制备和脱水成本即成为输送成本的一部分 Large volume of water is needed for slurry preparation 矿浆制备需要大量的水 The water removed from slurry needs to be disposed off at the end of the pipeline-从矿浆脱出来的水需要在管道终端排走 First Kunming (China) International Science Seminar and Technical Exchange Meeting, Sept 11-13, 2007 Summary总结 Slurry pipelining is a commercially proven, reliable method for the long-distance transport of minerals 浆体管道输送是得到商业证明的长距离输送矿物的可靠方法 bauxite deposits are often remote, so ore transportation is a major part of the development equation-铝土矿矿床通常在很偏远的地方，因此矿石的输送便成为综合开发的一个主要部分 Bauxite ores present some design challenges – but careful application of proven design methods will lead to success- 在铝土矿的管道设计方面存在某些难题—但谨慎运用已经验证过的方法将带来成功 First Kunming (China) International Science Seminar and Technical Exchange Meeting, Sept 11-13, 2007 List of Selected Commercial Pipelines已选用的商业管道列表 First Kunming (China) International Science Seminar and Technical Exchange Meeting, Sept 11-13, 2007 List of Selected Commercial Pipelines已选用的商业管道列表 First Kunming
