A dense and viscous by-product from the vacuum distillation process, vacuum residue is a valuable feedstock in the production of paving-grade bitumen, fuel oil blending, and delayed coking units. UNKA SUN’s vacuum residue is characterized by its high carbon content and viscosity, making it a key component in Iraq’s downstream refining and asphalt infrastructure. Its commercial value lies in its versatility and adaptability to various upgrading technologies.
