GT-BTX PluS is a simple two-column extractive distillation technology that can process the FCC gasoline to either reduce the octane loss to near-zero while removing the sulfurs, or recovers benzene, toluene, and xylenes (BTX) to convert a portion of FCC gasoline into high-value petrochemical compounds.
It produces low-sulfur, high-octane gasoline and valuable aromatics, increases refinery profitability, and reduces operating costs.GT-BTX PluS has two operating modes when processing FCC gasoline. At gasoline mode, it produces ultra-low sulfur gasoline with maximum octane numbers than any other desulfurization technology. At petrochemical mode, it extracts aromatics to convert a portion of FCC gasoline into high-value BTX petrochemical products. GT-BTX PluS unit can easily switch between gasoline mode and petrochemical mode, making an invaluable flexibility for the refinery to quickly adapt the change of the market demand, to always produce the product for the highest profitability.
Through a simple two-column extractive distillation process and proprietary solvent, sulfur is effectively removed from the gasoline stream without losing the octane number. Traditional FCC gasoline hydrodesulfurization will saturate significant amount of olefins that result in octane number reduction. GT-BTX PluS will separate the sulfur from olefins to avoid olefins being ever exposed to hydrotreating. By saving the olefins from going through hydrodesulfurization, the octane number is reserved.
Certainly. GT-BTX PluS can be easily dropped into the existing FCC gasoline configuration regardless of whether there is a hydrodesulfurization unit or what type of hydrodesulfurization unit there is. Existing equipment will continue to be reused or undergone minor modifications. The project payback is typically within 3 years.
GT-BTX PluS is the ONLY extraction- & distillation-base technology that can process FCC gasoline to produce ultra-low sulfur gasoline with near-zero octane loss. It is also the only technology that can extract aromatics from FCC gasoline and therefore convert a portion of it to high-value BTX petrochemical product. All other FCC desulfurization technologies cannot produce BTX product, and while it only produce gasoline, it lose significant octane number to meet the ultra-low sulfur spec.
