Visbreaking
Visbreaking is a process unit used in petroleum refineries that reduces the viscosity of the residual oil from the refinery's atmospheric or vacuum distillation of petroleum crude oil and increases the yield of more valuable middle distillates (fuel oils) by the refinery.
The process name of "visbreaking" refers to the fact that the process reduces (i.e., breaks) the viscosity of the residual oil.
NoDoC simulates the cost for visbreaking for two methods: Coil visbreaking and Soaker visbreaking.
Coil cracking, visbreaking, uses higher furnace outlet temperatures (470 – 500 °C) and few minute reaction times. Soaker cracking uses lower furnace outlet temperatures (430 – 450 °C) and longer reaction times. Soaker visbreaking has the advantages of lower energy consumption and longer run times before having to shut down to remove the coke from the furnace tubes. Disadvantage is that soaker drum cleaning is difficult and time consuming.
