Latest Patents

Li Zhang holds a patent for a "Unit for producing and separating aromatics with recovery of an extract and/or raffinate from a liquid-liquid extraction process." This invention relates to a production and separation device and method wherein a reforming effluent is produced and fractionated in a separation unit and a fractionation train for extracting benzene, toluene, xylenes, and C-aromatics. Aromatics are extracted from a feedstock in a liquid-liquid extraction unit to produce a first raffinate and a first extract. The first extract is sent to a benzene-toluene fractionation device. The xylenes are separated in a xylene separation unit to produce a second extract containing para-xylene, and a second raffinate containing ortho-xylene and meta-xylene. The second raffinate is isomerised in an isomerisation unit to produce an isomerate enriched in para-xylene sent to a fractionation train.
