Habshan Sulfur Granulation

180,00-tonne covered-storage stockpile.

11,000-tonne-per-day sulfur-granulation plant.

75-km pipeline.

Challenges

GASCO set out to build the largest integrated gas-to-liquids refinery in the world.
Liquid sulfur would arrive from existing Habshan gas plants via skin-effect electrical tracing (SEET) pipelines.
The liquid sulfur would then be granulated at the facility, stockpiled, and ultimately transported via rail to a new sulfur handling terminal at Ruwais.
The right measurements were required to effectively handle the friable sulfur granules and mitigate concerns surrounding fire hazards.

Provided detailed engineering and procurement support services for the upstream liquid-sulfur delivery pipeline and the downstream bulk-material-handling facility.
Included two stacker-reclaimers in the bulk-material-handling system that were integrated within a conveyor network that then connected to a railcar-loading facility.

The materials-handling system used many automation strategies to ensure the designed "hot-spare" redundancy provisions were effective.
Developed a custom stockpile-management philosophy to eliminate shelf-life issues for sulfur kept in storage.
With 12 granulators and an extensive network of sulfur pipelines, this is one of the largest sulfur granulation installations in the world.
