This manuscript highlights tangible benefits deriving from the dynamic simulation and control of operational transients of natural gas processing plants. Relevant improvements in safety, controllability, operability, and flexibility are obtained not only within the traditional applications, i.e. plant start-up and shutdown, but also in certain fields apparently time-independent such as the feasibility studies of gas processing plant layout and the process design of processes. Specifically, this paper enhances the myopic steady-state approach and its main shortcomings with respect to the more detailed studies that take into consideration the non-steady state behaviors. A portion of a gas processing facility is considered as case study. Process transients, design, and control solutions apparently more appealing from a steady-state approach are compared to the corresponding dynamic simulation solutions.
本文重点介绍了天然气加工厂运行瞬态的动态模拟和控制所带来的切实好处。不仅在传统应用中(如工厂的启动和关闭),而且在某些明显与时间无关的领域(如天然气加工厂布局的可行性研究和工艺设计),都获得了安全性、可控性、可操作性和灵活性方面的相关改进。具体来说,本文通过考虑非稳态行为的更详细研究,增强了短视的稳态方法及其主要缺点。以一个天然气处理设施的一部分作为案例研究。对从稳态方法来看显然更有吸引力的工艺瞬态、设计和控制解决方案与相应的动态模拟解决方案进行了比较。
