HOUSTON, Oct. 10 -- Hellenic Petroleum SA has selected ExxonMobil Research & Engineering Co.'s flexicoking technology for an upgrade project at its 100,000 b/cd refinery in Elefsis, Greece.
ExxonMobil will supply a 20,000 b/d flexicoking unit, which will convert vacuum residue to lighter products.
Flexicoking integrates fluid bed coking and air gasification to eliminate petroleum coke. It allows refiners to process vacuum resid, atmospheric resid, oil sands bitumen, heavy whole crudes, deasphalter bottoms, or thermal cracked tar to produce higher-value liquid and gas products.
Flexicoking produces a clean low-sulfur fuel gas, which can be used economically in refinery furnaces and boilers, as well as by power plants to minimize nitrogen oxides and sulfur oxides emissions.
