ANCHORAGE (AP) -- Anchorage-based Petro Star has received a $1.3 million grant for a $2.2 million project to determine if a new process to remove sulfur from diesel fuel can be used by small to medium-sized oil refineries.
The current sulfur removal process is too expensive for smaller refineries to use.
The U.S. Department of Energy grant comes from the Alaska Science & Technology Foundation, which co-funded Petro Star's first stage of work.
petroleum refineries are having to comply with stricter federal Environmental Protection Agency guidelines, the foundation said.
Petro Star is owned by Barrow-based Arctic Slope Regional Corp. and has refineries at North Pole and Valdez.
The company and its partners are contributing $900,000 of their own money to the project, officials said.
