Excerpts from the vocational skills question bank for hydrocracking units

(1) Operation and maintenance: To ensure the proper operation of the hydrogen production facility, its moving parts should be inspected regularly, as well as the proper functioning of various analytical instruments, such as those for measuring temperature, humidity, pH value, pressure, flow rate, and concentration. (2) Control: It involves managing the operating conditions of the hydrocracking unit, adjusting operational parameters to ensure the reliability of the equipment and stable performance, checking the quality and concentration of the feedstock, and making adjustments to the feed concentration in order to ultimately ensure safety and production efficiency. (3) Repair and maintenance: Conduct regular maintenance on the hydrocracking units to improve the operating environment, repair faults that occur before shutdowns, ensure the actual operational quality of the equipment, carry out maintenance and calibration tasks, and provide professional inspection and maintenance, especially for equipment such as transformers.
