Lean amine is generally not corrosive because they have either low conductivity and/or high pH. Corrosion rates increase with increasing temperatures, particularly in rich amine service. Temperatures above _________ can result in acid gas flashing and severe localized corrosion.

A. 170º F
B. 190º F
C. 220º F
D. 240º F

Answer :

Final answer:

Lean amine, despite its low conductivity or high pH, becomes corrosive at high temperatures, particularly above 240º F, leading to acid gas flashing and severe localized corrosion.

Explanation:

The question is concerned with the corrosive attributes of lean amine, a chemical often used in gas plants.

High temperatures, specifically temperatures above 240º F, can lead to a circumstance known as acid gas flashing in rich amine service, subsequently leading to severe localized corrosion.

While amine is generally not corrosive, due to its low conductivity and/or high pH, it becomes susceptible to corrosion in conditions of rising temperatures.
