ASTANA, Kazakhstan, May 4. The Shymkent oil
refinery in Kazakhstan, a subsidiary of KazMunayGas, has completed
scheduled preventive maintenance works (SPM), which began on March
27 this year, Trend
reports via KMG.


The refinery finished the maintenance works three days ahead of
the schedule approved by the Ministry of Energy of Kazakhstan.
Primary oil processing units resumed operations on April 22, while
deep oil processing units returned to production on May 2.


During the maintenance period, inspections were carried out on
more than 573 pieces of equipment and 170 pipelines. Major
overhauls were also performed on key furnaces and processing units,
including the ELOU-AT atmospheric and vacuum distillation unit,
diesel hydrotreating unit, and catalytic cracking unit.


More than 2,000 specialists and 222 units of special equipment
were involved in the works, with particular attention paid to
occupational safety and industrial safety standards.


Thanks to pre-formed reserves, the refinery ensured stable
supplies of petroleum products throughout the maintenance period,
maintaining continuity in the domestic fuel market.







The company noted that the current maintenance cycle marks an
important milestone for the Shymkent refinery, as the plant has
transitioned to an extended inter-repair period. The next
large-scale maintenance is scheduled for 2030, while a short-term
turnaround of selected units is planned for 2028. This will allow
the refinery to operate with fewer long shutdowns, ensuring stable
output for the domestic market.


The scheduled preventive maintenance is carried out in
accordance with Kazakhstan’s Law on Civil Protection. These works
ensure the safe and uninterrupted operation of the refinery, as
well as compliance with environmental standards.


The Shymkent oil refinery, built in 1985, is the most recent
refinery in Kazakhstan. The refinery accounts for approximately 30%
of the country's total oil products, produced across three
refineries. As the only refinery in southern Kazakhstan, it serves
the region’s most densely populated area. The Shymkent refinery
produces gasoline to the K4 standard, including grades RON-95 and
RON-92; K4 standard diesel fuel in grades DT-L, DT-E, and DT-Z; jet
fuel TS-1; fuel oil M-100; liquefied gas; and sulfur in flake
form.
