A visbreaker is a chemical plant based on a techology whereby via thermal cracking in a furnace reactor (at high temperature) heavy hydrocarbons (e.g. vacuum distillation residue) is transformed into lighter hydrocarbons. Heavy hydrocarbons are generally used as fuel oil in chemical plants. The product of the visbreaker has a lower viscosity. In ecomomic terms this means that less diluents have to be added to use the vacuum residue as fuel oil. The name visbreaker literally means "breaks the viscosity". Thermal cracking such as visbreaking is in general less efficient than catalytic cracking. A Chemical plant is an industrial process plant that manufactures chemicals, usually on a large scale. ... In petroleum geology and chemistry, cracking is the process whereby complex organic molecules (e. ... A furnace is a device for heating air or any other fluid. ... Chemical Reactors deal with several aspects of chemical engineering. ... In chemistry, a hydrocarbon is any chemical compounds that consists only of carbon (C) and hydrogen (H). ... Vacuum distillation is a method of distillation whereby the pressure above the solution to be distilled is reduced to less than one Atmosphere (unit) causing evaporation of the most volatile liquid(s) (those with the lowest boiling points. ...
