Road Maps to Corrosion Inhibitor Program

Below are guidelines on how to build oilfield production corrosion inhibitors program, start with the basics.

1. Sweet Gas Corrosion

2. CO2 & Low Level H2S

3. CO@ & High Level H2S

 

Sweet Gas Corrosion

These chemical are mostly water soluble and the sweet gas corrosion is high general corrosion. The chemistries to build corrosion inhibitor finished products include:

Imidazoline

Quats

Phosphate esters

Eythoxylated amines

CO2 & Low Level H2S

These are very common systems and the corrosin is mostly general with pits. The chemistries to build these corrosion inhibitor products also include:

Imidazoline

Phosphate esters

Quats

Alkyl Pyridine quats

Sulfiding agents

Ethoxylated amines

CO2 & High Level H2S

The general corrosion rates are normally low, however the pitting corrosion rates are high and the chemistries to build these corrosion inhibitor products include:

Organic amines

Quats

Imidazoline

Sulfiding agents

Alkyl pyridine quats
