| Abstract: | Design and evaluation data for the 900 kt/a aromatics extraction unit of Petrochina Guangxi Petrochemical Company were contrasted and analyzed.In the evaluation,the contents of benzene and toluene in the feedstock were beyond the design range,which made the operating flexibility of the benzene-toluene section reach the design upper limit 115%,and mole fraction of the olefins in the feedstock was 0.94%,which was also higher than that in the design cases,but the unit still ran smoothly and the product quality... |
