High-purity sulphur from Frasch process operations
The Frasch process is a specialized method for extracting elemental sulphur from underground deposits. Superheated water is injected into the sulphur deposit, melting the sulphur, which is then pumped to the surface as a liquid.
This method produces exceptionally pure sulphur (often 99.5%+) and is particularly effective for deposits located in salt domes, which are common in the Gulf of Mexico region.
Major Frasch process operations
The Gulf Coast region, particularly around Houston, has been a major center for Frasch process sulphur production. These operations leverage the region's salt dome geology and established infrastructure.
Mexican Frasch operations contribute significantly to global sulphur supply, with operations located in regions with suitable geological formations.
Superheated water (typically 160-165°C) is injected under pressure into the sulphur deposit through an outer pipe, melting the solid sulphur.
Compressed air is introduced through an inner pipe, creating a froth that brings the molten sulphur to the surface through a third pipe.
The liquid sulphur is collected in large vats where it solidifies into high-purity blocks or is further processed into other forms.
