1. In a method for reducing at least one of acid corrosion and products of acid corrosion in a thermal cracking ethylene production plant wherein said corrosion products are compounds of at least one metal of the group consisting essentially of iron, chromium, nickel, lead, cadmium, manganese, mercury, magnesium, calcium, sodium, copper, zinc, palladium, molybdenum, and aluminum, the improvement comprising introducing into at least one process stream in an olefin processing unit ethylenediamine in an amount sufficient to reduce said acid corrosion and remove at least one said products of acid corrosion.
2. The method of claim 1 wherein said acid corrosion and said acid corrosion products are caused by at least one organic and inorganic acid chemically reacting with a physical part of said plant.
3. The method of claim 1 wherein said acid is at least one of acetic, formic, oxalic, propionic, isobutyric, carbonic, sulfurous, sulfuric, hydrochloric, hydrofluoric, nitric, nitrous, and benzoic.
4. The method of claim 1 wherein said at least one acid is present in said at least one stream in an amount of from about 1 to about 5,000 parts per million.
5. The method of claim 1 wherein said at least one acid is employed in said at least one stream under the normal operating conditions of temperature and pressure for that stream in said plant.
6. The method of claim 1 wherein said compound is at least one of the oxide, nitrate, sulfate, carbonate, and sulfide of said at least one metal.
7. The method of claim 1 wherein said ethylenediamine is introduced in an amount effective to neutralize at least some of said acid in said at least one stream.
8. The method of claim 7 wherein said amount is from about 10 parts per billion to about 10 weight percent based on the total weight of the stream being treated.
9. The method of claim 1 wherein said ethylenediamine is injected directly into said at least one stream to be treated.
10. The method of claim 1 wherein said ethylenediamine is dispersed in a carrier fluid and the carrier fluid containing the ethylenediamine is injected into said at least one stream to be treated.
11. The method of claim 10 wherein said carrier fluid is a hydrocarbon.
12. The method of claim 11 wherein said hydrocarbon is one of isooctane, naphtha, diesel, and gasoline.
