Tomer Hello, I'm chemical engineer working in a petroleum refinery. We have a visbreaking(Thermal cracking) unit in our refinery. For a constant Furnace outlet temperature, we were suffer from high viscosity of the feed to the visbreaker and we have difficulty to find the source if it is the unit itself or some unit/stream upstream the visbreaker' as someone deal with something like this? also We would like to know, what type of Vacuum residue feed is desirable for Visbreaker unit, to attain good conversion and higher ratio of viscosity between feed and bottoms? in addition, Does the visbreaker conversion will influence the viscosity ratio of feed and bottom?
