【Q&A Question 242】September 5, 2018: Briefly describe the key principles that should be considered when a malfunction occurs in a hydrogenation unit 1. Prevent fires and explosions; priority should be given to the operations in areas where explosions are likely to occur. 2. Strictly prevent voltage coupling at the connection points between high and low voltages. 3. To prevent significant economic losses, it is necessary to strictly avoid overheating of the reactor bed, protect the catalyst, and ensure gas flow through the reactor bed. 4. Prevent leakage, emission, and cross-contamination. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Safety first: personnel safety, equipment safety, catalyst safety.
Safety first: personnel safety, equipment safety, catalyst safety
People-oriented: prioritize protecting human safety first； Next is to ensure environmental protection by preventing illegal discharges, and to promptly separate waste from clean water streams ； Furthermore, it aims to reduce economic losses and protect important equipment and catalysts ； Finally, consider optimization measures to shorten the next start-up cycle.
The order of protection is: 1. Personnel, 2. Catalysts, 3. Equipment. In the event of a failure, it is strictly prohibited that high pressure bypasses low pressure or that the catalyst temperature rises excessively
Safety first. Equipment and catalysts.
Safety first, people. Equipment and catalysts are both quite important.
Answer: 1. To prevent fires and explosions, priority should be given to operations in areas where explosions are likely to occur. 2. Strictly prevent voltage coupling at the connection points between high and low voltages. 3. To prevent significant economic losses, it is necessary to strictly avoid overheating of the reactor bed, protect the catalyst, and ensure gas flow through the reactor bed. 4. Prevent leakage, emission, and cross-contamination.
Safety first; priority is given to protecting the safety of personnel, equipment, and catalysts
