[Chemical Process Information] The first unit of China’s third-generation aromatic hydrocarbon technology with independent intellectual property rights, CCCC

Thread Content

Jiujiang Petrochemical's 890,000 tons/year aromatic hydrocarbons plant, the first industrial unit built using Sinopec's independent intellectual property third-generation aromatics technology, was built to high standards. The CCCC project developed and applied a single-tower adsorption separation process and a new generation of adsorbent package technology for the first time. Compared with the previous double adsorption towers, the "two swords combined" became a single adsorption tower, which can effectively reduce investment costs by nearly 20% and make operations more stable.； The application of new catalysts in the process has higher activity, stability and conversion rate, and the application efficiency has increased by more than 10%. ； Through optimization of the entire process of the aromatics combined unit and other related measures, the energy consumption is reduced by 30% compared with similar aromatics units, reaching the international leading level.
