Planned Preventive Maintenance Completes at Atyrau Refinery
Planned preventive maintenance (PPM) of 32 process units has been completed at the Atyrau Refinery.
The units were repaired one by one, which made it possible to avoid stopping the oil products output. It should be noted that it was the first time when the practice of staged maintenance of units was applied at domestic refineries.
The following were completed according to the PPM schedule: replacement of catalysts, internal inspection, audit and certification of reactor, tank, column, heat exchange equipment and pipelines, repair (inspection) of pumping and compression equipment, examination and inspection of process furnaces, preventive maintenance and repair of power equipment, instrumentation and automation.
During the repair, the plant worked at 50-70% capacity with output and shipment of target products. In October-November, the plant processed 581.4 thousand tonnes of oil. The average daily processing amounted to 9,531 tonnes, which is 57% of the plant’s design capacity. At that, the average daily output of petroleum products was as follows: motor gasoline − 1,570 tonnes/day, diesel fuel − 2,100 tonnes/day, jet fuel − 120 tonnes/day, liquefied gas − 155 tonnes/day.
