in the second step, the product is brought to the desired final viscosity in the mass-flow reactor. This reactor was designed
with a view to a narrow residence time spectrum. A narrow residence time spectrum is an important prerequisite for a narrow
IV spectrum. In the third step, the product is quickly cooled using a pulse bed cooler, where it is also efficiently de-dusted.
The refined product can now be processed. The process continues at higher temperatures under nitrogen. The gas travels
through an energy-saving circuit and is purified in multiple steps. Gas loss is minimal and easily replaced via a control valve.
