Abstract The amount of silicon in naphtha must be controlled because it results silica deposits vehicle components, such as spark plugs, catalytic converters, and oxygen sensors, which can lead to fuel economy degradation, increased emissions, damage converters. Naphtha has low specific gravity high volatility; plasma does not form during analysis using inductively coupled plasma-optical emissi...
Introduction An aromatics complex is a combination of process units that can be used to convert petroleum naphtha and pyrolysis gasoline (pygas) into the basic petrochemical intermediates: Benzene Toluene and Xylenes (BTX). Benzene is a versatile petrochemical building block used in the production of more than 250 different products. Ethylbenzene, cumene, and cyclohexane are the most important ...
Petroleum heavy vacuum gas oil (HVGO) containing 10 wt.% of petroleum wax was hydrocracked at 390–430 °C and under the pressure 18 MPa over a Ni W/amorphous silica-alumina catalyst in continuous-flow fixed-bed reactor. The hydrocracking reference feed (neat HVGO) carried out same reaction conditions. physico-chemical properties primary products obtained via laboratory atmospheric-vacuum distill...
in thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. in this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. the model is used to predict the steady state profiles of the gas temperature and product yields. using a dy...
