Visbreaking Process Types

Visbreaking is not a single design but a family of thermal-cracking approaches, each suited to a different residue and product goal. Understanding the main visbreaking process types helps a refinery pick the configuration that minimizes coking while maximizing usable yield.

Coil Visbreaking

In coil visbreaking, the cracking reaction happens entirely inside the furnace tubes at high temperature and short residence time. The rapid, tight conditions suit feedstocks that need only mild viscosity reduction and deliver high throughput with a compact footprint.

Soaker Visbreaking

A soaker drum downstream of the furnace extends reaction time at slightly lower temperature. This gentler profile improves light-product yield and reduces furnace coking, making it a popular choice when refineries want a balance between yield and equipment longevity.

Delayed and Hydrogen-Assisted Routes

Delayed visbreaking holds cracked feedstock at lower temperature to soften the reaction and suppress coke. Hydrogen-assisted and hydrogen-donor variants introduce hydrogen to stabilize lighter fractions and further curb coke formation, at higher capital cost.

Choosing the Right Configuration

The best visbreaking process type depends on feedstock asphaltene content, target viscosity, and desired distillate output. Klean Industries evaluates these variables and delivers the unit design that matches the operating reality of each plant.

One residue, several cracking routes. Choose with data, not habit.

The right visbreaking configuration lifts yield and cuts coke, paying for itself in lower maintenance.

Klean Industries models coil, soaker, and hydrogen-assisted options to match your feedstock and margin goals.
