Visbreaking is cracking reduces the viscosity of the vacuum residue and converts the residue to valuable products that otherwise can not be recovered from the residue by conventional distillation. Visbreaking lowers pour points of waxy residues and enables the refiner to blend heavier materials with lighter fuel oils. Coil temperatures can be raised to increase the yields of lighter products just until coke formation starts to lead to a pressure increase across the visbreaker coil.

Can you convert centimeters cubec to centimeters squared?

No. You can't just convert any unit to any other unit. The units must be of a compatible type. Thus, you can convert a unit of length to another unit of length, a unit of area to another unit of area, or a unit of volume to another unit of volume.No. You can't just convert any unit to any other unit.

How do you remove wax from crude oil?

Wax is not removed from crude oil until it reaches the refinery. Several processes allow for the removal of wax from crude oil. In many cases the wax is not removed at all, but sent as residue to be broken down thermally in a coking unit or visbreaking unit. Other options include solvent dewaxing which involves adding a large amount of solvent in a ratio of 3:1 to 12:1 to remove the wax in a heavier product known as pitch. Solvent dewaxing is a dated process, and today wax removal is more commonly accomplished by using a catalyst at high temperature and pressure to isomerize the waxy "paraffin" molecules into more usable products (isoparaffins). Isoparaffins have a better viscosity index than paraffin and are typically used as lubricating oils for engines, turbines, etc.
