Title:
SYSTEM AND METHOD FOR PREPARING AROMATICS BY USING SYNGAS
Document Type and Number:
WIPO Patent Application WO/2019/000381
Kind Code:
A1
Abstract:
A system and a method for preparing aromatics by using syngas, the system comprising: a syngas purification unit (1), a syngas conversion unit (2), a syngas to aromatics preparation unit (3), a gas-liquid separation unit (4), a liquefied gas separation unit (5), a dried gas separation unit (6), a dried gas transformation unit (7) and an oil–water separation unit (8). The method reforms the separation of a liquefied gas and dried gas as well as the water vapor of a dried gas so as to produce carbon monoxide and hydrogen, which are returned to a syngas aromatization reaction system as raw materials, thus solving the problem of the utilization of by-products, and reducing the unit consumption of syngas per ton of aromatic product. Starting from the angle of a recycling economy, the system and method solve the problem of the utilization of by-product dry gas, and reduce water consumption during the preparation process, complying with the idea of green chemistry.
