Description

System for adsorber regeneration and related method Cross-reference regarding related applications This application claims the benefit of concurrently pending U.S. provisional patent application No. 63/580,642 filed on September 5, 2023, the entire contents of which are incorporated herein by reference. Technology field The present disclosure relates to a system for regenerating an adsorber and a method related thereto. More specifically, it relates to a system for removing "target impurity" material from a main process flow by one or more regenerable efficient adsorbers. The regenerated material for these adsorbers can be recirculated back to the main process after condensation, purification, and vaporization/heating. In chemical processes such as refining and fuel production, carbon footprint and energy efficiency are key factors that environmentally conscious manufacturers or producers must consider. For example, existing processes are inefficient and incur additional costs to enable. Furthermore, existing processes are not energy-efficient and do not possess a low carbon intensity (CI) index. Therefore, it is advantageous to provide improved systems to address these requirements. The present disclosure provides a system for regenerating an adsorber and a method related thereto. The system of the present invention is configured to regenerate a target impurity substance (e.g., carbon monoxide CO, carbon dioxide CO2 , and/or water) in an adsorber of a main process flow (e.g., ETJ (ethanol-based jet fuel) production flow). Embodiments of the target impurity substance may include, for example, oxygenated compounds such as alcohols, ketones, aldehydes, as well as nitrogen compounds such as ammonia, acetonitrile, and/or pyrazine. The system of the present invention may include (1) a condensation/cooling module; (2) a regeneration (or "cleaning") module; and (3) a vaporization/heating module. The condensation/cooling module is configured to cool an impurity-loaded process flow. The regeneration module is configured to regenerate or "clean" the cooled, impurity-loaded process flow. The system of the present invention also uses a "regeneration" material to remove target impurity materials. Examples of "regeneration" materials include regenerated naphtha (e.g., combustible liquid hydrocarbon mixtures, etc.). In some embodiments, the regeneration module may perform a distillation process for the regenerated material. In some embodiments, the regeneration module may (A) dispose of separated impurities to a suitable destination, such as a flare, a closed drain, fuel gas, etc.; (B) purge the regenerated material back into the product process or main process stream so that it can be used elsewhere; and (C) add a replacement material to address potential degradation of the regenerated material over time. In some embodiments, the recycled material may be naphtha. In some embodiments, the recycled material may be a SAF (Sustainable Aviation Fuel) product. In some embodiments, the recycled material may be an alkane having a low olefin content (e.g., less than 1 percent by weight). In other embodiments, the recycled material may be a regenerated alkylate product, isobutane, etc. The vaporization/heating module is configured to heat or vaporize the cleaned regenerated material (i.e., the material processed by the regeneration module) to form high-temperature regenerated material vapor, and this vapor can subsequently be sent back to the main process flow. In some embodiments, the system may have a parallel structure of a dryer or other adsorber (e.g., a CO2 adsorber) before the condensation process performed by the condensation/cooling module and after the vaporization/heating process performed by the vaporization/heating module. Embodiments of the parallel structure are discussed in detail with reference to FIGS. 3 and 4. The system and method of the present invention are not limited to the ETJ process. In some embodiments, the system and method of the present invention may also be applied to the alcohol-based jet fuel production (ATJ) process and/or the alcohol-based hydrocarbon production (ATH) process. In some embodiments, the method and system of the present invention may also be implemented for systems supplied with "non-ethanol" alcohols (e.g., isobutanol) and for other products such as high-octane gasoline and regenerated diesel. In some embodiments, the method of the present invention may be implemented by a non-transient, tangible computer-readable medium storing processor instructions that, when executed by one or more processors, cause one or more processors to perform one or more aspects/features of the method described herein. In other embodiments, the method of the present invention may be implemented by a system comprising a computer processor and a non-transient computer-readable storage medium storing instructions that, when executed by the computer processor, cause the computer processor to perform one or
