pre-hydrogenation
Thread Content
Why does semi-regenerative reforming require an arsenic removal reactor? But continuous reforming doesn’t!
Pre-hydrogenation generally consists of a pre-hydrogenation reactor and a high-temperature dechlorination reactor; pre-hydrogenation catalysts usually have the function of removing arsenic as well. What kind of craftsmanship is this from?
I’ve seen both semi-regenerative and continuous regeneration processes, but I’ve never encountered a setup in which an additional arsenic removal reactor is used. Could you show me your PID diagram?
This is mainly designed to protect the catalysts at the back; it is estimated that there are arsenides in your raw materials. .
