SegaFlix Pre-HDS BioCatalyst

Pre-Hydrodesulphurization (Pre-HDS) is a refining process that removes sulphur from petroleum feedstocks before they undergo further processing, such as catalytic cracking or hydrocracking. It operates at a pressure of 760 mmHg (1 atm) and utilizes a liquid catalyst to break down sulphur compounds.

By reducing sulphur content early in the refining process, Pre-HDS enhances the efficiency of downstream units, protects catalysts from deactivation, and ensures compliance with environmental regulations.

Test Result

After the catalytic treatment and distillation process, the sulphur content in the distillate product will be reduced by up to 49%, while most of the sulphur will remain in the distillation residue. The distillate product is easier to treat with a hydrodesulfurization unit.

Sulphur content in distillate before and after catalytic treatment:

After the catalytic treatment and distillation process, the sulfur content in the distillate product will be reduced by up to 26%, with most of the sulfur remaining in the distillation residue. The distillate product is easier to treat with a hydrodesulfurization unit.
