Lump sulfur, also known as granular or rock sulfur, is typically characterized by a purity of 99.80% or higher, with a maximum ash content of 0.05%.
It should also have a limited acidity (H2SO4) of 0.02% or 0.03% and minimal moisture content (0.5% or 0.2%).
More detailed breakdown of lump sulfur specifications:
Purity:
Dry Basis: 99.80% minimum purity is a common specification.
Other Standards: Some standards like Refinery Specifications, may specify a purity of 99.98%.
Impurities:
Ash Content: A maximum ash content of 0.05% is a typical requirement.
Acidity: A maximum acidity (H2SO4) of 0.02% or 0.03% is common.
Organic Substances: Some specifications limit organic substances to 0.01% or 0.03% maximum.
Moisture: A maximum moisture content of 0.5% or 0.2% is generally specified.
Mechanical Impurities: Some specifications require the absence of mechanical impurities like paper, wood, or sand.
Other Impurities: Some standards specify limits for arsenic, selenium, tellurium, and lead impurities.
Color and Appearance:
Color: Bright yellow is the typical color specification.
Other Considerations:
Test Methods:
Specifications often include test methods, such as ASTM D-4239, ASTM D-1509, ASTM D-1613, and ASTM D-2790, for determining the various parameters.
Bulk Density:
Granular sulfur has a bulk density of around 70 lb/cu ft (1121.29 kg/cu m).
Solubility:
Sulfur is insoluble in water, partially soluble in acetone, and slightly soluble in diethyl ether and alcohol.
