The sulphur produced at gas plants in Central Alberta results from the processing of natural gas containing hydrogen sulfides or "sour" gas. Using state-of-the-art sulphur recovery technology, hydrogen sulfide is converted into sulphur. "Sour"gas is common in deep natural gas deposits in Alberta. Almost 90 percent of all elemental sulphur produced in Canada comes from sour natural gas processing. The rest comes from oil refineries and oil sands plants.

Rotoform® Pastilles  | Sulphur produced by Shell is available as both formed and molten product. The majority of our product is produced as Rotoform which Shell has been instrumental in pioneering. Our Sandvik Rotoform pastilles form is the latest generation of a premium sulphur product. The many desirable characteristics of Rotoform have made it a popular choice in markets around the world. |
Rotoform Description Rotoform pastilles have a lot in common with miniature chocolate chips. In fact they are formed with the same type of equipment. This produces a product that is uniform in size and density. This offers many advantages to the end user. - It allows for even burn rates. With virtually identical pastilles, the melting process occurs in a consistent fashion.
- Made of a durable crust, they are resistant to breaking which reduces the likelihood of dust escaping from the product. Having no edges or corners to break off, eliminates environmental and safety handling problems.
- Rotoform Pastilles enables seamless storage, handling, and processing. They can be more efficiently and accurately measured, which increases their economic contribution.
- Product loss due to moisture and acidity are reduced due to its uniform shape and compression.

Molten Sulphur Ninety percent of all sulphur sold to U.S. markets is shipped in "molten" or liquid form. Sulphur in molten form is a practical, environmental, and economic method of shipping. Liquid sulphur is normally handled between 132-143 degrees C (270-290 degrees F). It is transported in insulated rail cars, which are equipped with heating coils. These coils act to remelt any sulphur that solidifies while the sulphur is in transit so complete unloading can occur.
