May I ask about the catalysis exam questions?
Thread Content
Airtight operation of the two vessels; shutdown procedures for the booster pump; determination of instrument failures; reading of schematic diagrams of the main equipment in the distillation system; control of the liquid level at the bottom of the distillation tower; airtight operation of the two vessels; inspection of compressor operation; determination of backburning in the regenerator; reading of schematic diagrams of the main equipment in the stabilization system; shutdown procedures for the main fan; shutdown procedures for the air compressor; operation procedures for the external heat exchanger; determination of water content in the feed oil; reading of schematic diagrams of the main equipment in the reaction and regeneration system
Having been in the field of catalysis for ten years, when I see these problems, I feel as if I’m looking at my own family members!
Although there are only a few questions, they cover the knowledge required for the entire system
