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.

» Processing Natural Gas NaturalGas

The process for removing hydrogen sulfide from sour gas is commonly referred to as 'sweetening' the gas. The primary process for sweetening sour natural gas is quite similar to the processes of glycol dehydration and NGL absorption. In this case, however, amine solutions are used to remove the hydrogen sulfide.
