Refineries constantly seek ways to improve product yields, reduce operating costs, and extract greater value from heavy petroleum residues. Heavy fuel oil (HFO) and other residual streams often contain high-boiling hydrocarbons that have limited commercial value compared with lighter petroleum products. Converting these heavy fractions into more valuable products is therefore an important part of refinery optimization.
HFO visbreaking units provide a practical thermal conversion solution. By applying controlled heat to heavy residual oil, visbreaking reduces viscosity and promotes the formation of lighter hydrocarbon fractions. This process helps refineries improve residual oil utilization while maintaining a balance between product quality, operating costs, and process reliability.
