摘要：

Aiming at the stability problem of corrosion inhibitor film of the high sulfur gas gathering pipelines with two-phase turbulent flow, the corrosion inhibitor film stability with typical pipe flow in high sour gas field was evaluated by using the dynamic corrosion test system with high temperature and high pressure cyclic reactor. The inhibitor prefilm stability was better when the flow velocity was below 6 m·s-1 and it began partial failure when the flow rate exceeded 7.5 m·s-1, while it was completely failure under the action of flow shear force when the flow rate reached 9 m·s-1. The fluid dynamics study showed that the shear stress of 6.5 N·m-2 was the critical point of the inhibitor film being overall damaged. ©, 2015, Chemical Industry Press. All right reserved.
