NAPHTHA

Naphtha is a low octane cut from atmospheric distillation of crude oil from the topping plant usually in the range between 30 °C–200 °C and constitutes typically 15–30% by weight of the crude oil [1]. This cut contains some impurities such as sulphur, oxygen and nitrogen compounds. This low run naphtha, sometimes referred to as straight run, requires reforming to a more valuable higher run naphtha called reformate which is blended into a pool of gasoline for use as a motor spirit. SR naphtha can be Light naphtha a fraction with boiling point ranging from 30 °C to 90 °C, containing the C5 and C6 hydrocarbons or Heavy naphtha which is the fraction with boiling range from 90 °C to 200 °C.
