Atyrau Oil Refinery
In July 2023, Atyrau Oil Refinery was the first among large oil refineries to start production of AI-92 motor gasoline of environmental class K5 (Euro-5 analogue). As part of the policy of NC KazMunayGas to reduce emissions into the environment, ANPZ switched to production of motor gasoline of K5 ecological class. The main advantage of this ecological fuel is reduction of sulphur compounds content five times in comparison with K4 class. Also, the content of aromatic hydrocarbons (benzene) and additives is limited in K5 class petrol, the report says.
It is noted that the reduction of toxic emissions when using K5 class fuel contributes to the reduction of harmful effects on human health, including irritations and diseases of the respiratory tract, inflammatory processes, negative impact on the nervous and cardiovascular systems.
In addition, the use of K5 grade petrol has a positive effect on vehicle performance.
It is emphasised that the achievement of K5 gasoline quality became possible due to the launch of new technological units during the three-stage modernisation of the enterprise. The average daily production volume of AI-92-K5 gasoline is 5.5 thousand tonnes.
