Inventors include Ladkat, Kiran; Corradi, Jason T.; Werba, Gregory R.; and Maithil, Sourabh.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: Aromatic transalkylation processes are described which reduce the hydrogen makeup gas requirement to the aromatic transalkylation unit and improve the energy efficiency of the aromatics complex. The processes may utilize a hot separator, optionally one or more flash drums, and optionally a stripper column. The aromatic transalkylation separator bottom liquid may be preheated and flashed to a low-pressure drum to separate light hydrocarbons, such Ci to Cs, as a vapor stream from the aromatics rich liquid hydrocarbons stream. A portion of flash drum liquid may recycled back to a product condenser inlet as a sponge liquid to absorb the light hydrocarbons from the reactor effluent stream and thereby improve the hydrogen purity of the recycle gas (RG) without purging RG.
