Scheduled Maintenance of Process Units Starts at Atyrau Refinery – Refinery to Continue Generation of Oil Products
According to the approved preventive maintenance schedule issued by the RoK Ministry of Energy, the preventive maintenance campaign commenced at the Atyrau Refinery on 1 October 2022.
The process facility maintenance will be performed on a stage-by-stage basis. The Atyrau Refinery’s units operate according to the two-stream oil refining pattern and are shut down and started alternatively. Thus, the refinery will not be completely shut down. The refinery will continue to operate at the 50–70 % capacity during the maintenance, generating and shipping the target products.
In October to November, it is planned to refine 692,000 tonnes of oil. The average daily refining rate will be 11,347 tonnes, which corresponds to 68 % of the refinery’s design capacity. The average daily oil product generation volume will be as follows: 2,400 tonnes of motor gasoline per day, 2,600 tonnes of diesel fuel per day, 240 tonnes of jet fuel per day and 170 tonnes of liquefied gas per day.
The preventive maintenance at the Atyrau Refinery will be carried out according to the Industrial Safety Law On Civil Protection of the Republic of Kazakhstan to ensure safe and reliable operation of the process, power generation, compression and dynamic equipment so as to achieve the design performance, improve the environmental parameters and inspect the automation equipment.
The following works will be performed on the units during the scheduled maintenance: catalyst change-out, internal inspection, inspection and examination of reactors, tanks and vessels, columns, heat exchangers and pipelines.
The Atyrau Refinery’s ramp-up to stable operation is also scheduled on a stage-by-stage basis by the second ten-day period of November 2022.
As a reminder, the plant maintenance was previously expected to commence in September 2022. However, in order to stabilise the situation on the fuel and lubricants market, the maintenance was postponed to 1 October 2022.
