The reference answers can be seen after responding; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) The adjustment of air coolers is mainly achieved by changing the angle of the fan blades in order to regulate the air flow rate. For air coolers equipped with louvers, the air flow can be adjusted by changing the opening degree of those louvers. There are both manual and automatic methods for such adjustments. In cases where several air cooling units operate in parallel, it is also possible to adjust the air flow by shutting down one or more of them. Scoring criteria: 2 Wealth points for incorrect attempts; 3–8 points for *incomplete* answers. 10 Wealth points for correct answers, provided with detailed explanations; 15–20 Wealth points if the answer is correct but lacks sufficient details.
