Visbreaker - Wikipedia
A visbreaker is a processing unit in an oil refinery whose purpose is to minimize the quantity of residual oil produced in the distillation of crude oil and to increase the yield of more valuable middle distillates (heating oil and diesel) by the refinery. A visbreaker thermally cracks large hydrocarbon molecules in the oil by heating in a furnace to lower its viscosity and to pro… 展开
Process objectivesThe objectives of visbreaking are:
• Lower the viscosity of the feed stream: Typically this is the residue from
• Lower … 展开
Visbreaking Process in Petroleum Refinery
To avoid coking in the fractionation tower, the quenching phase is crucial. The most frequent quenching streams are gas oil and Visbreaker residue. After quenching, the effluent is transferred to the fractionator’s lower section, where …
