Iron Sulfide Control. Iron sulfide presents many challenges in the oil and gas industry. Its presence indicates a problem in the production stream and will cause problems across all aspects of production and transmission. Iron sulfide causes corrosion by bonding to metal surfaces and causing an electrochemical reaction that degrades metal.

Black powder can collect in gas pipelines, leading to flow loss and premature failure of compressors, instruments, and other equipment. (Photograph courtesy of Southwest Research...

The typical Unisulf process flow diagram is reported in Fig. 6, where all the characteristic H 2 S liquid redox process sections can be distinguished: the absorber, to wash the H 2 S containing feed gas; the oxidizer, to complete the H 2 S to S conversion; the finishing sulphur section, to allow the production of high purity sulphur.

Ideally in amine systems treating for H2S, iron sulfide particles would be handled by designing the unit such that velocities remain low enough that the iron …

Reaction 3 Iron oxide reacts with organic sulphur or hydrogen sulphide (H2S): Soluble organic iron species such as iron carboxylates and iron naphthenates are likely to decompose at higher temperatures, reacting with organic sulphur or H2S to form FeS deposits on process equipment surfaces. Their decomposition temperature is >300°C.
