Help: Teaching materials for coking vocational skill assessment

Thread Content

**In the vocational skill assessment for coking, the task related to distillation mainly includes the refining of crude benzene, the distillation of crude benzene, the refining of tar, ammonia distillation, and the distillation of naphthalene. Some information is needed for this; those who have it could please share it. Thank you – it will definitely be taken into account as extra points! Here are some of my questions: 1. What instruments are used in crude benzene refining, crude benzene distillation, tar refining, ammonia vaporization, and naphthalene distillation? It would be great if relevant principles and knowledge could be provided~! 2. What are the components of the automatic control instruments used in crude benzene refining, crude benzene distillation, tar refining, ammonia vaporization, and naphthalene distillation? 3. What are the conditions and mechanisms underlying fires, explosions, and poisoning during the refining of crude benzene, the distillation of crude benzene, the refining of tar, ammonia distillation, and the distillation of naphthalene? 4. What are the first-aid basics for human accidents in crude benzene refining, crude benzene distillation, tar refining, ammonia evaporation, and naphthalene distillation? 5. In the processes of crude benzene purification, crude benzene distillation, tar purification, ammonia evaporation, and naphthalene distillation, how can the recovery rate, purity, and extraction efficiency of the products be improved? What are the best practices for organizing production in order to achieve high quality, high yields, and low consumption? How should start-up and shutdown procedures be organized? 6. In these processes, how can the various process parameters of the distillation towers be evaluated and adjusted? How is the reflux ratio calculated? How should material balances be conducted for single towers (reactors, vessels)? Which energy sources and media should be chosen? 7. What are the various operating procedures involved in crude benzene purification, crude benzene distillation, tar purification, ammonia evaporation, and naphthalene distillation? How should quality-related operational accidents be handled, and what kind of accident analysis reports should be prepared? These are the issues I need to study. I appreciate any suggestions you might have; it would be great if there were relevant materials available, but even without them, any insights would be helpful. Some people might ask why I don’t write the answers myself. Let me explain: My factory only employs processes related to crude benzene distillation and ammonia evaporation, which are part of steel coking. Therefore, I’m not very familiar with the distillation processes involved in the purification of crude benzene, tar, and naphthalene, and that’s why I’m seeking advice from everyone. Additionally, the vocational skill assessments for coking industry only cover distillers as a general category, which is why I’m asking these questions. On a side note: Which factory’s distillers are proficient in all the processes related to crude benzene purification, crude benzene distillation, tar purification, ammonia evaporation, and naphthalene distillation? And do they also take part in the vocational skill assessments for the coking industry?
