Solution for the sulfur injection amount in reformation
Thread Content
The feed rate to the reforming unit is 75 t/h. The sulfur content in the feed material is 0.05 ppm, while the required sulfur content is 0.25 ppm. What is the volume flow rate of sulfides per minute? (The sulfide is dimethyldisulfide, with a molecular weight of 94 and a relative density of 1.063 g/ml)

This is a question from the operator’s manual for catalytic reformers
Adjust accordingly based on H2S levels
