Corrosion Monitoring Solution for Amine Units

摘要

As every process engineer knows, H2S and C02 must be removed from the natural gas process stream to ensure the final product meets pipeline specifications and fulfills the obligations of environmental emissions legislation. "These acidic contaminants are typically removed with aqueous mixtures of Alkanol-amines and/or alkylalkanol-amines in a regenerative process," says Emerson. "The handling of acidic process streams and rich amine solutions will always result in corrosion by nature of these compounds."
