Method and composition for inhibiting the corrosion of metals |
摘要 |
A method and composition for inhibiting the corrosion of metals in contact with an acid-gas absorbing medium comprising adding a product of the reaction of (1) copper or a copper salt, a copper oxide or a copper sulfide and (2) sulfur or a sulfide and an oxidizing agent and (3) a monoalkanolamine (monoethanolamine). The reaction is carried out at from 21 DEG to about 100 DEG C for a period of time to produce a stable non-precipitating product, i.e., reacted for from 0.1 to about 20 hours. The product is added to a gas treating plant absorbent in an amount of at least 0.00002 pounds of copper and 0.0002 pounds of sulfur per pound of medium per day.
