The first phase of Rijeka Refinery modernization consisted of three facilities within Hydrocracking complex and other supporting facilities and installations, which include Mild hydrocracking (MHC/HDS), Hydrogen generation unit and Desulphurization plant (Claus).

The total investment into first phase of Rijeka Refinery modernization is approximately EUR400m.

The company said that through the hydro cracking of heavy hydrocarbons, lighter products will be extracted, and by the hydrodesulphurization of these lighter products, it will get EURO V fuels.

Hydrogen generation unit is designed for supplying of Hydrocracking plant with high purity hydrogen, according to the company.

Besides hydrogen, the plant produces also high pressure steam that is used for production of electricity. Desulphurization plant in the first phase processes the amine acid gas and sour gas with high level of ammonia.

This plant is able to isolate at least 99.8% of the sulphur present in the total input.
