Dbeibeh signed a decree on the refinery near the Sharara field, authorising NOC to contract work directly and to finance construction projects.
The refinery should generate returns of $75 mln per year, according to Sanalla.
In addition to the refinery, the plan also covers an LPG plant.
The Libyan cabinet approved the refinery plan at the end of September.

The company has been working on refinery plans since 2017.
Talks on additional refining capacity in Libya date back to 2013.
