Figure 4 Configuration of the combined Prime-G+ and GT-BTX PluS technology in petrochemical mode
Summary Incorporating the combined Prime-G+ and GT-BTX PluS technologies is a transformative investment for refineries. This single investment affords refineries the dual capabil - ity to optimise both gasoline and petrochemical produc- tion, irrespective of ever-fluctuating market dynamics. The intrinsic operating flexibility enables refineries to pivot their focus instantly, whether the demand is for gasoline or petrochemicals. In an industry where adaptability is synonymous with success, the Prime-G+ and GT-BTX PluS integration emerges as an indispensable asset for all FCC-equipped refineries. By embracing this technology, refineries can confidently navigate the intricate landscape of post-pandemic refining, reaping significant benefits and securing a competitive edge.
(HDS) in the Prime-G+unit, culminating in a high-quality petrochemical BTX product (benzene, toluene, xylenes). Furthermore, the olefin-rich non-aromatics raffinate stream derived from GT-BTX PluS proves invaluable for FCC recycling, producing significantly additional propyl - ene and enhancing the FCC propylene yield. Alternatively, if aromatics is the focused product, this raffinate can be routed to a fixed-bed GT-Aromatization unit, coupled optionally with LCN, driving substantial BTX production. Figure 4 shows the mentioned two options of combined technology in the petrochemical mode for converting a significant portion of FCC gasoline into petrochemical products. Operating flexibility of the combined technology The true strength of the Prime-G+ and GT-BTX PluS inte - gration lies in its exceptional operating flexibility. Refineries can seamlessly switch between gasoline-focused and petrochemical-centric modes of operation. This adapt - ability is crucial as market demands oscillate, necessitating rapid shifts in production focus. By adopting this combined technology, refineries across diverse regions gain the agil - ity to swiftly align their production strategy with prevailing market requirements.
