Visbreaking Unit Feedstocks

A visbreaking unit takes the lowest-value ends of the refinery and gives them a second life. The visbreaking unit feedstocks it can handle range from heavy vacuum residue to tank bottoms, each chosen for its ability to yield marketable heavy fuel oil and lighter distillates.

Vacuum and Atmospheric Residue

Vacuum residue is the heaviest, most asphaltic cut from the vacuum tower, while atmospheric residue is somewhat lighter. Both carry long-chain hydrocarbons that respond well to mild thermal cracking, making them the backbone feeds for viscosity reduction.

Sludges and Tank Bottoms

Beyond tower bottoms, visbreaking units can process crude-oil sludges and accumulated tank bottoms, recovering value from streams that would otherwise be treated as waste. This flexibility lets a refinery monetize streams with high asphaltene and sulfur content.

Blended Residue Streams

Refineries frequently blend vacuum and atmospheric residues to tune feed characteristics and optimize yield. The resulting mix balances cracking behavior and helps the unit hit a target viscosity and fuel specification without excessive coke.

Products From the Bottom of the Barrel

Output includes reduced-viscosity heavy fuel oil plus naphtha, middle distillates, and light gases for refining and fuel. Klean Industries configures visbreaking units around your exact feed slate and product targets.
