Sulfur Removal

  • Process audit (study) of sulfur recovery unit and recommendations on process optimization;
  • Development of solutions for reactor loading, supervision at stages of catalyst loading/unloading, start-up and shutdown of sulfur recovery unit;
  • Testing of catalyst physicochemical properties and performance before-and-after service using advanced scientific instrumentation;
  • Manufacturing and supply of in-house catalyst package.

Sulfur Removal Challenges Our Solutions
