As a leading tank car lessor, it is our obligation to deliver railcars that fit the specific needs of our customers. One such opportunity recently presented itself when a customer transporting molten sulfur asked us to design and deliver rail tank cars. Our experienced team was excited and ready to execute; focusing to ensure all transport and loading/unloading requirements were met along with delivering a safe and easy-to-use design.
Sulfur is a pale yellow crystalline solid and in its molten form is a liquid. Sulfur must be transported in a molten state, otherwise it crystallizes and cannot be loaded or unloaded. The challenge is to keep its liquid state because the melting point of sulfur is around 115°C. Railcars are typically filled with molten sulfur at approximately 150°C and must maintain a minimum temperature of 120°C during transport.
Oliver Behrens, Technical Development Officer at GATX Rail Europe and his team are responsible for new build projects. Oliver said, “Even with our extensive experience, we still come across interesting product transport challenges… like molten sulfur.”
