Start-up process of crack gas compressorsvia dynamic simulation
摘要
Abstract
The crack gas compressors are the core equipment of the ethylene plant, whose smooth start plays an important role in the whole plant’s start-up process. In traditional start-up process, the crack gas compressors start with the crack gas, which is replaced by other working mediums in recent years, such as nitrogen, natural gas or mixed hydrocarbon. Due to the impossibility to test on the equipment, the chemical engineering simulation technology has become the important tool to solve these problems. In this paper, according to the “steady-state/dynamic/start-up” method, a steady-state simulation model of crack gas compressors is built, and the steady-state operation parameters of the crack gas, nitrogen and mixed hydrocarbon were determined. Then, the steady-state model was converted to the dynamic model. At last, the safety and feasibility of transformation process between various working conditions were verified.关键词
