Question 67

For carbon steel, common velocity limits are generally limited to _________ fps for rich amine and _______ fps for lean amine.

    Correct Answer: D

    For carbon steel, common velocity limits are generally limited to 3-6 fps for rich amine and 20 fps for lean amine. These limits help prevent localized thickness losses due to high velocities and turbulence, which can cause amine corrosion.

Discussion
ahmadmmOption: D

Amine corrosion is generally uniform; however, high velocities and turbulence will cause localized thickness losses. For carbon steel, velocities are generally limited to 3 fps to 6 fps (1 m/s to 2 m/s) for rich amine and about 20 fps (6 m/s) for lean amine.
