MOL plc (Budapest, Hungary; www.mol.hu/en) has selected Axens Axens (Rueil-Malmaison, France; www.axens.net) to perform the revamping of its DMHCK unit (FCC feed hydrotreater and mild hydrocracking) at the Danube Refinery in Százhalombatta, Hungary. This revamping project consists in increasing vacuum gas oil (VGO) conversion and diesel yield.
The existing DMHCK unit was commissioned in 1992 with a 4,500 metric ton (m.t.) per day capacity, and was further upgraded using a non-Axens technology to allow the processing of Heavy Coker Gas-Oil (HCGO) with a design capacity of 6,000 m.t./d.
For the new revamping, Axens offered its latest catalyst series, which enables conversion increases without significant modifications to reactors and major equipment. The required unit modifications identified by Axens will be implemented in a way that minimizes unit downtime.
