Sulfur Prilling for Oil Refineries – Southern British Columbia; Washington State

Key Challenge

These refineries produce molten sulfur as a by-product of their clean fuel products operations. Because of insufficient regional demand for the by-product and limited storage, it must be removed on a consistent and uninterrupted basis to avoid any impact on the refineries’ core operations.

Solution

Molten sulfur is transported to the Marsulex facility in Mount Vernon, Washington where it is converted into solid spherical shapes called “prills.” The prilled sulfur is marketed into the international market and shipped by vessel around the globe.

Result

• Refiners have a dependable and reliable service that enables them to achieve uninterrupted refinery operations.
• Economies of scale achieved by servicing multiple sources maximize refiners’ by-product value.
