The morphology of nano gamma alumina affects the molecule adsorption-desorption phenomena. In this case, manipulating surface area, pore volume, and size by technique preparation to control textural properties alumina. Washing synthesized boehmite gel with methanol has a significant effect. co-precipitation method was used prepare alumina, which is involved adding drop-by-drop ammonium hydroxid...

In this study, an artificial neural network (ANN) model was developed and compared with a rigorous mathematical (RMM) to estimate the performance of industrial heavy naphtha reforming process. The ANN model, represented by multilayer feed forward (MFFNN), had (36-10-10-10-34) topology, while RMM involved solving 34 ordinary differential equations (ODEs) (32 mass balance, 1 heat balance momentum...

The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are clas...

Abstract The study focuses on corrosion challenges for naphtha hydrotreating equipment (installed upstream of a reforming unit) caused by ammonium chloride deposits and the development adequate chemical engineering protection measures. Using an experimental setup, we investigated sublimation/desublimation at varying pressures temperatures in medium typical hydrogen-bearing gas streams flowing f...

Power-to-Liquid (PtL) plants can viably implement carbon capture and utilization technologies in Europe. In addition, local CO2 sources be valorized to substitute oil gas imports. This work’s aim was determine the PtL efficiency obtained by combining a solid oxide electrolyzer (SOEC) Fischer–Tropsch synthesis. recommended plant configuration produce synthetic fuel wax at pilot scale is establis...

Among the current IPPC installations, steam cracking for olefin production is the single most energy consuming process (ca. 30%) in the chemical industry, accounting for ca. 180 million tons of CO2 worldwide. This paper reviews steam cracking and innovative emerging olefin technologies in terms of energy efficiency. Pyrolysis section alone consumes ca. 65% of the total energy use and ca. 75% of...
