Hydrogen Sulfide formation in Oil and Gas

Draft 2 Abstract Hydrogen sulfide (H 2S) can be a significant component of oil and gas upstream production, where H2S can be naturally generated in situ from reservoir biomass and from sulfate containing minerals through microbial sulfate reduction (MSR) and/or thermochemical sulfate reduction (TSR). On the other hand, the technologies employed in oil and gas production, especially from

Iron - Wikipedia

Pig iron is not a saleable product, but rather an intermediate step in the production of cast iron and steel. The reduction of contaminants in pig iron that negatively affect material properties, such as sulfur and phosphorus, yields cast iron containing 2–4% carbon, 1–6% silicon, and small amounts of manganese.
