Naphtha, Heavy Naphtha and Light Naphtha

Solis Oil works to locate specific Naphtha to meet the refinery’s specifications, with the end goal of providing a consistent supply chain & logistics, adjusting to the customer’s changing needs, and providing real time customer service. Solis Oil’s management of Naphtha includes terminal purchases, pipeline shipping purchases, barge allotments, rail car and general transportation for a variety of fuel oils.

What is Naphtha

Naphtha is the first petroleum product produced during the distillation process and subsequently upgraded to make the major components of gasoline. Virgin or straight-run Naphtha is the largest source of Naphtha in most petroleum refineries. The virgin Naphtha is often further distilled into two streams:

•a virgin light Naphtha with an IFP of about 30 °C and a FBP of about 145 °C contains most (but not all) of the hydrocarbons with 6 or less carbon atoms.
•a virgin heavy Naphtha with an IFP of about 140 °C and a FBP of about 205 °C contains most (but not all) of the hydrocarbons with more than 6 carbon atoms.

Virgin heavy Naphtha is usually processed in a catalytic reformer because the light naphtha has molecules with 6 or less carbon atoms and lower molecular weight hydrocarbons which are not useful as high-octane gasoline blending components.

Naphtha's Unique Composition

Worldwide, there are hundreds of different petroleum crude oil sources, each with their own unique composition. There are also hundreds of petroleum refineries worldwide, each designed to process either a specific crude oil or specific types of crude oils. Because of this individuality, it is virtually impossible to provide a definitive, single definition of the word Naphtha. Each refinery produces its own Naphtha with its own unique initial and final boiling points, and other compositional characteristics. Therefore, Naphtha is a generic term rather than a specific term.
