Pyrophoric iron sulfide results from the corrosive action of sulfur compounds on the iron and steel used in refinery process equipment, piping, and tanks. The combustion of petroleum products containing sulfur compounds produces undesirables such as sulfuric acid and sulfur dioxide.
Sunflower Processing - Crown Iron Works
Oil Refining and Processing. Extracted and desolventized sunflower oil must be further processed to make an edible product. Edible oils are refined to improve the flavor, odor, color and stability using processes that degum, neutralize, bleach and deodorize the oil. These refining processes remove contaminants such as phosphatides, free fatty ...
Refining (metallurgy) - Wikipedia
· Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.
Refined Iron - Feed The Beast Wiki
Refined Iron is an item formerly used in many important IndustrialCraft 2 recipes, such as the Machine Block or Electronic Circuit. It could be obtained by smelting an Iron Ingot or Refined Iron Dust. It is now crafted using the Industrial Blast Furnace. As of Minecraft 1.6 and IndustrialCraft 2 Experimental, crafting
Refining Gold | HowStuffWorks
The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals.

Steelmaking and Refining | Introduction to Chemistry
The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal known as finers metal or refined iron.

Pyrophoric Iron Removal | Oil Refining | Carus Corporation
During the refining of crude petroleum, the sulfur component of the crude oil reacts with the specialty alloy steel processing equipment producing iron sulfide scale. Pyrophoric iron sulfide scale, when exposed to air, reacts exothermically and can result in a fire. Toxic sulfide odors can also be formed during these turnarounds.

Physical and Chemical Process in Palm Oil Refining Plant
Palm Oil Physical Refining Process. Oil physical refining process, also called as oil steam refining. During the degumming section in the palm oil milling plant, the gum will be removed from palm oil by utilizing phosphoric acid or citric acid. Next to bleaching section, the coloring matter and other metal ions will be absorbed or removed.
Oil Refining-Pyrophoric CAIROX POTASSIUM …
Permanganate oxidizes pyrophoric iron sulfide to iron sulfate eliminating the potential for exothermic reactions and fires or explosions during shut downs for maintenance of refinery process equipment. Permanganate treatment also controls toxic odors by oxidizing the sulfides to odorless sulfates.
The Refining Process - How Oil Refining Works - Science
Newer techniques use Chemical processing on some of the fractions to make others, in a process called conversion. Chemical processing, for example, can break longer chains into shorter ones. This allows a refinery to turn diesel fuel into gasoline depending on the demand for gasoline. Refineries must treat the fractions to remove impurities.
Secondary Refining - steel.org

Metallurgic Processes | Boundless Chemistry
The term "refining" is used in a narrower context. Henry Cort's original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
