The monthly production of cyclohexanone in Baling Petrochemical's caprolactam section reached a new high in October, surpassing the historical maximum level of 686 tons, which was 1.24 times of the same period of the previous year. It provided raw material guarantee for caprolactam production and reduced procurement cost.
Since the beginning of the year, the supply of cyclohexanone, the main raw material for caprolactam production, has been tight, and the procurement cost has increased. In this regard, the caprolactam portion of Baling Petrochemical Co., Ltd. optimizes the operation load of the cyclohexanone refining unit on the one hand, activates the old dehydrogenation system, and deep-processes the purchased ring. Hexanol, try to reduce the purchase amount of cyclohexanone; on the other hand, revitalize idle assets, promote the maintenance of cyclohexane oxidation high-pressure equipment for 6 years of shutdown, and successfully resume production in early August, and increase the production of high-quality cyclohexanone by more than 150 tons per day. .
In view of the simultaneous operation of two sets of equipment in the cyclohexanone workshop, the caprolactam department strengthened the concept of 'on-site is king, service site', and two managers from the agency were enriched to the workshop, and seven production operators were transferred from other workshops to fill the shift. First line. The cyclohexanone workshop implements the 'director responsibility system', implements the leadership rotation and shift system, and timely solves specific problems.
The Ministry continued to optimize the operation of the re-engineering cyclohexane oxidation high-pressure device, increasing the circulation and ventilation from 0.95 in the initial stage of driving to the current interval of 1.05-1.1, effectively increasing the proportion of ketol in the discharge. The ketone refining device has problems with alkali in the waste alkali evaporation system under high load conditions. The workshop management and technicians creatively propose improvement measures, and the effect is good after implementation.
The department has developed detailed equipment special protection programs. The operators conduct on-site inspections every hour to record the operation of key equipment compressors and oxidation kettles in detail. Strictly implement equipment shutdown, receiving, cleaning and inspection procedures to ensure timely operation of equipment. Alternate. Each team carried out the search and rectification of the site 'run, run, drip, leak' activities, and successively checked more than 200 leak points, and the machine pump cut out more than 40 leaks, which promoted the stable operation of the device.
