常减压含硫污水管线的腐蚀特性
Corrosion characteristics of sulfide-containing wastewater pipeline in atmospheric and vacuum distillation
摘要
Abstract
The sulfide content of crude oil has increased in recent years due to the inferior quality of crude oil.Therefore,wastewater pipelines are at great risk of corrosion.In order to reduce the corro-sion risk of pipeline,the corrosion characteristics of sulfide-containing wastewater pipeline are investi-gated based on electrochemical experiment and numerical simulation.The results show that the corro-sion rate of sulfide-containing wastewater on the pipe wall is firstly proportional to the temperature,and then inversely proportional to the temperature.The corrosion rate of pipe wall is maximized at 60℃.The S2-in the wastewater can weaken the ionization of the corrosive components H2S.When the concentration is high enough,the corrosion effect on the pipe wall is greater than the inhibition effect,which leads to the gradual increase of the corrosion rate.The distribution of wastewater on the pipe wall of the sulfide-containing wastewater straight pipeline is related to the inlet flow rate and flow velocity.The high-risk area of corrosion is located at the tee for the junction of the wastewater when the pipe is full of wastewater.关键词
