Hello,

 

I'm working at a oil refinery and we operate a Visbreaker unit in order to decrease the viscosity of our vacuum residue.

lately we're suffering from very high viscosity in the feed to unit and accordingly in the exit stream.

As anyone familiar with this case or have any idea what could couse such a problem?

 

thank you,

 

Tomer.

change of crude?

change of cut points in the VDU upstream?

What you need is a solution. That would be to add diluent to reduce the viscosity of the product to specification.
