Computer modeling has become an indispensable tool used for the every phase of a long distance slurry pipeline project starting from conceptual design and case studies through basic and detailed design, and lastly as an operational tool used to develop operating procedures for normal, upsets, and emergency conditions. Ultimately, the simulator can also be used as the base to build leak detection software and digital controls for the system. Using the simulator, vivid graphic displays provide the design engineer immediate feedback on a case under investigation. Also, it provides a means to judge whether input data and assumptions are viable. In this paper an example is illustrated showing how dynamic modeling and graphic displays are used to: (1) analyze the use and characteristics of a 'wear' valve, (2) provide designer and operator with a vivid understanding of system operations. The paper illustrates how dynamic simulation easily and efficiently analyzes a slurry pipeline process condition. In this case, wear valve operation and characteristics. As one would suspect, mitigating the differential pressure by reducing stroke time and maintaining positive down pressure benefits the utility life. Most interestingly, one can conclude that small differences in valve characteristics can have significantly large differences regarding its durability in slurry service.
