摘　　要：延迟焦化炉炉内结焦是影响装置连续、安全运行的重要因素之一。本文基于HYSYS流程模拟软件,在原有加热炉动态模型的基础上,嵌入延迟焦化炉炉内结焦模型,开发了一种模拟延迟焦化炉炉管内结焦过程的新方法,实现了延迟焦化炉的动态流程模拟。从而在满足工艺要求和安全生产的前提下,有助于实现对结焦速度进行先进控制,达到延迟焦化反应产物效益最大、能耗最少目标。通过与某炼油厂延迟焦化炉实际运行数据的比较,验证了所提方法的可行性和有效性。Coke deposition problem of the delayed coking furnace is one of the important factors that affect continual and safe production of the delayed eoking process. In this paper, a new method was developed to dynamically simulate coke deposition process for the delayed coking furnace, by embedding a coke deposition model into the dynamic furnace operation of HYSYS. Therefore, with the satisfaction of constraints on the production safety and appropriate eoking rate, the advanced control and online optimization could be used to maximize the benefits of the delayed eoking production and reduce the cost. Compared with the practical processing data of a real delayed eoking furnace, the simulation results based on the proposed method demonstrated its feasibility and validity.
