Does butane have a corrosive effect on copper?
Thread Content
Dear teachers, I encountered a problem during the production process. The pump used for transporting butane has ring seals and balance drum sleeves made of copper; there is a glue-like layer on the surface of the copper, along with slight corrosion. Normally, copper does not react with liquefied gas. Please help analyze this issue.
What you say makes sense. C4 needs to be properly desulfurized; otherwise, hydrogen sulfide can cause certain corrosion to copper
