The company said in a press release Tuesday its new particle separator, the first of its kind in Romania, reduces pollution to levels four times lower than required under EU environmental legislation.

Rompetrol Rafinare general manager Yedil Utekov said the company invested over $600 million in technology and environmental protection at the Petromidia refinery starting 2008.

Rompetrol Rafinare is part of KMG International (formerly known as Rompetrol Grup), controlled by Kazakh state-run oil and gas company KazMunayGas.

KMG International is one of the well-established oil companies operating in Romania and an important player in the Black Sea and Mediterranean Sea basins. The company is primarily active in refining, petrochemical, retail, trading, upstream and industrial services.
