Overview
Sulfur (S) is a non-metallic element widely produced as a by-product of natural gas processing and petroleum refining (via hydrodesulfurization). In solid form, sulfur is a bright yellow crystalline substance with numerous industrial, agricultural, and chemical applications. It is a critical raw material in the production of sulfuric acid, fertilizers, chemicals, and pharmaceuticals, as well as in rubber vulcanization and metal processing.
