The project was conceived in 2001, while the main contractors were selected in late 2002. The investment includes a diesel fuel desulfurization unit with annual capacity of 2.2 million tons, a gasoline desulfurization plant with 750,000-ton capacity, and a 40,000 ton per year hydrogen production unit.
Following the upgrades, MOL now only sells gasoline with sulfur content of just 10 ppm, while the company has been selling diesel fuel exclusively of such quality since January this year. MOL is considered an early mover in this regard, because such low sulfur content in vehicle fuel will only be required by the EU starting 2009, with the current limit set at 50 ppm.
By implementing desulfurization investments in just one step, instead of meeting 2005 criteria first and upgrading later, MOL has saved some 50-60% on investment costs, according to MOL executive chairman Zsolt Hernadi. As a result of selling practically sulfur-free fuel, total sulfur emissions in Hungary will drop to just 30 tons a year, down from 730 tons now and as much as 35,000 tons in the early 1990s, according to Hernadi.
