Sulfur is a component in the production of Sulfuric acid and Explosives, both of which are also intermediate products used in higher-level recipes. Sulfur is a solid item in a chain of otherwise fluid-based manufacturing: Crude oil → Petroleum gas → Sulfur → Sulfuric acid .
The plant has a production capacity of 300 000 tpy of sulfuric acid, and is the world's largest such facility. It will treat 131 000 t of acid gas over-the-fence per year from the neighbouring world scale refinery plant operated by a joint venture (JV) between China National Offshore Oil Corp. (CNOOC) and Shell in Huizhou City, China.

A cheap high-sulfur fuel such as petroleum coke can be used for power generation, while the flue gas is cleaned in SNOX plant under production of sulfuric acid. Elemental sulfur is fired in the SNOX plant in order to produce the desired amount of sulfuric acid.
PYRITE ROASTING, AN ALTERNATIVE TO SULPHUR BURNING M Runkel and P Sturm Outotec , Oberursel GERMANY Abstract ... material basis for sulfur dioxide production, especially as the primary stage for sulfuric acid manufacture.
And then by mixing sulfur dioxide with water in a contact process, we create sulfurous acid (H2SO3) and the sulfur trioxide produces sulfuric acid (H2SO4). This is also the origin of acid rain. When high-sulfur coal is burnt it produces the same gases and the same chemistry happens in the clouds.
