... refineries and first reported in the late 1800 s.1 It is considered as a uniform corrosion with the formation of metal sulfide scales. The current existing tool for prediction of the sulfidic corrosion rate is the modified McConomy curves. The McConomy calculations utilize the total sulfur content...

... ABSTRACT Formation of mineral scale is one of the primary complications affecting production in the oil and gas industry. Soured reservoirs contain hydrogen sulfide (H 2 S) that can prompt the formation of exotic sulfide scales, leading to detrimental fouling that negatively affects...

... ABSTRACT Iron sulfide scales are formed by sulfur corrosion on the inner walls of refinery distilling towers and transfer lines operating on sour crude oils. Sulfide scales are generally considered to partially reduce corrosion by other corrosive species in crudes, especially naphthenic acids...

... ABSTRACT Glass cell experiments were conducted to investigate the mechanism and kinetics of mild steel corrosion in H 2 S environments which is accompanied by iron sulfide scale formation. By using the weight change method, the rates of corrosion and scale formation were found. It was also...

.... Low carbon steel with no aluminum, formed a continuous, and somewhat dense, iron sulfide scale that provided some protection. Small additions of aluminum (5-7.5 wt Yowl) resulted in the growth of iron sulfide as nodules or a porous surthcescale. Larger additions (above10 w 0/0)were to limit the growth...

... was 500 hours. Relatively thick, mixed sulfide scales were formed on all of the alloys tested. Also, internal carburization occurred within all of the alloys. The use of x-ray diffraction allowed the phases constituting the scales to be identified, and these phases were in agreement with previous...

... yielding sulfide scales with significantly enhanced FILC resistance. The change in FILC susceptibility is accompanied by a change in scale morphology and thickness. In order to quantify erosion corrosion intensities developed by a submerged jet stream, surface roughness profiles were correlated via...
