保证所有管道中石油从一端流向另一端不泄漏要比它的探测更加困难。比较图中的3个系统,可以看到这项技术在40多年来是如何逐步发展的。世界上最大的蒸汽发电工厂之一坐落在美国一个主要城区的岛上,这座工厂在当地服务区域范围内为人们提供暖气和空调所需的蒸汽,然而它必须要从大约2英里以外的燃油贮油库中提取燃料。复杂的是,在这段2英里的距离中其85%的管道都要穿过水流湍急的河道,考虑到其实际的环境条件,燃油运输系统必须要加以密切监控,以保证燃油不会在管道输送过程中流失。这家工厂从河流对岸的油槽罐中提取6号燃油,然后再用油泵对燃油加压通过一段压力可控管道穿越河道,这条输油管道其最大流量为300gpm。输油管道泄漏监测
It is more difficult to ensure that all the pipeline oil flows from one end to the other without leakage. Comparing the three systems in the figure, you can see how this technology has evolved in more than 40 years. One of the world’s largest steam power plants is located on an island in one of the main urban areas in the United States. The plant provides steam for heating and air-conditioning in areas served by the local area. However, it must operate from about 2 miles away from the fuel Fuel extraction from storage depots. Complicatingly, about 85% of the pipeline at this 2-mile span passes through fast-moving rivers, and given its actual environmental conditions, the fuel-handling system must be closely monitored to ensure that fuel will not flow in the pipeline Drainage during transport. The plant extracts oil 6 from the tank on the opposite side of the river and then pumps it to pressurize the fuel through a pressure-controlled pipeline that has a maximum capacity of 300 gpm.
