Gasoline aromatization and desulfurization (GARDES) technology is extensively used in refineries of Petrochina, aiming to produce high quality ultraclean fluid catalytic cracking (FCC) gasoline. This article introduces the industrial application results on the hydrodesulfurization unit of the Hohhot refinery, which plays an important role in guiding next round gasoline upgrading. The characteristics and the principle of GARDES technology were elaborated by analyzing the distribution of sulfur and hydrocarbon compounds in the feed and product. The analysis results proved that the presence of broad ranged sulfur types in the feed can be removed at different stages. Olefin can be decreased by saturation and conversion into i-paraffins and aromatics. The sulfur content of the blend product can be limited under 10 mg/kg, showing GARDES technology has excellent sulfur removal ability. The olefin reduction can also satisfy the ever-increasing severe requirement about the olefin limitation, while the loss of research octane number (RON) can be minimized to an acceptable level. Furthermore, according to the demand of gasoline upgrading, GARDES technology has great flexibility by adjusting operation condition without any further investment, which brings more economic benefits for refinery.

Operation Process

Feedstock conversion and yield products are studied through a 3D model simulating the main reactor of the fluid catalytic cracking (FCC) process. Computational fluid dynamic (CFD) is used with Eulerian-Eulerian approach to predict the fluid catalytic cracking behavior. The model considers 12 lumps with catalyst deactivation by coke and poisoning by alkaline nitrides and polycyclic aromatic adsorption to estimate the kinetic behavior which, starting from a given feedstock, produces several cracking products. Different feedstock compositions are considered. The model is compared with sampling data at industrial operation conditions. The simulation model is able to represent accurately the products behavior for the different operating conditions considered. All the conditions considered were solved using a solver ANSYS CFX 14.0. The different operation process variables and hydrodynamic effects of the industrial riser of a fluid catalytic cracking (FCC) are evaluated. Predictions from the model are shown and comparison with experimental conversion and yields products are presented; recommendations are drawn to establish the conditions to obtain higher product yields in the industrial process.

Abstract This paper presents the recent advances in pervaporative reduction of sulfur content in gasoline. Methods of preliminary selection of membrane active layer material are presented. Interactions between gasoline components (typical hydrocarbon and sulfur species) and membranes are showed. Influence of pervaporation process parameters i.e. feed temperature, downstream pressure and feed flow rate on the separation efficiency is discussed. Investigations of the influence of sulfur concentration in fluid catalytic cracking (FCC) gasoline on membrane performance have been conducted. A series of PV tests was carried out to investigate the separation properties of the commercial composite membrane with an active layer made of poly(dimethylsiloxane) and to determine the efficiency of organic sulphur compound (thiophene) removal from model thiophene/n-heptane mixture depending on its concentration.
