For a specific case of vibration in the gas-liquid two-phase flow pipeline of a certain unit's amine liquid pipeline, a method combining vibration theory was used. For existing projects where the vibration source cannot be temporarily eliminated, the method of changing the stiffness matrix and damping matrix of the vibrating pipeline was used to reduce the vibration impact. For new projects, the method of changing the pipeline direction was used to reduce or eliminate the impact of the vibration source on the pipeline. The study obtained the determination method for the degree of influence of two-phase flow pipeline vibration, the calculation method for the excitation force of pipelines with vibration problems, and the measures and methods to reduce two-phase flow pipeline vibration, providing reference for subsequent engineering.
