After more than two months of planned tunarnounds, the refinery of Slovnaft in Bratislava is now in full operation and its production is available for the domestic and foreign markets. A total of 21 production units have been gradually shut down since the end of May 2022. Slovnaft has invested more than EUR 60 million in their cleaning, maintenance and modernisation, thus reducing the environmental burden, increasing the energy efficiency of petroleum product production and strengthening the safety of complex technological processes.

"Slovnaft has successfully started up the last production unit in maintenance and thus completed the summer phase of planned turnarounds. Regular inspection, cleaning and maintenance of production equipment is an important and crucial part of safe and efficient operation of the refinery and petrochemical facilities. Slovnaft's production units are now fully operational again and the company is able to satisfy the needs of the domestic and foreign market," says Martin Bican, Head of Project and Turnaround Office at SLOVNAFT, a.s.

During the summer shutdowns Slovnaft spent almost EUR 36 million on the inspection and maintenance of its production facilities and invested more than EUR 24 million in their modernisation. During the most extensive summer part of the turnarounds, 21 production units were gradually shut down and restarted after the work was completed. The last of them was the Ethylene unit – a key part of Slovnaft's petrochemical production, where the first phase of the modernisation project was carried out, aimed at operational safety and lifetime extension. The production unit has new measuring instruments and control valves, new piping, and the reliability of compressor operation has also been improved. In total, approximately 1,800 external workers were involved in the works during the summer shutdowns.

A unique project within the summer phase of the turnarounds was the replacement of the aging atmospheric furnace on the Atmospheric Distillation 5 (AD5) unit, which had been in operation since 1967, with a new one. At the same time, the AD5 column was replaced with a new one, which makes the distillation process more efficient and reduces the risk of fire. The replacement of two pumps in the Circulation Center of the refinery brings a direct reduction in energy consumption. Electricity consumption within the Circulation Center should be reduced by 6.7% annually.

"Although the planned summer shutdowns were extremely demanding in terms of the scope and nature of the work, we were able to complete the required scope of work within budget without a major adverse event. The work during the summer shutdowns was in line with the principles and standards of the Turnaround Excellence programme, which aims to reduce the time of planned shutdowns and thus also the negative impact of the refinery operations on the residents in the vicinity of the refinery," adds M. Bican. Slovnaft informed about the impact of the works on the comfort of residents around the refinery on its website and via the Sused Slovnaft (Neighbor Slovnaft) mobile application.

This year's cycle of planned turnarounds will conclude in the autumn. Three production units will be shut down for approximately three weeks. In total, Slovnaft will invest a total of EUR 78 million in maintenance, repair and modernisation of more than half of its production units this year within the framework of three planned shutdowns – spring, summer and autumn.
