The Hungarian company MOL Plc. has selected Axens to perform the revamping of its DMHCK unit (FCC feed hydrotreater and mild hydrocracking) of the Danube Refinery in Százhalombatta, Hungary. This revamping project consists in increasing VGO conversion and Diesel yield.

The existing DMHCK unit was commissioned in 1992 with a 4500 MT/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 6000 MT/day.



For the new revamping, Axens offered its latest catalyst Series which enables conversion increases without significant reactors and main equipment modifications. The required unit modifications identified by Axens will be implemented in a way that minimizes unit downtime.

“This one of the most important project in MOL Refinery in the next years, therefore we have selected an experienced company with good references supremely meets our requirements. It was very important during the selection to minimize the CAPEX cost of the project.” said Zsolt Gulyás, Project Manager, MOL Plc.
