Shanxi Coking Chemical passed the optimization of technical indicators last year, which resulted in a total refining rate of 98.6% for benzene products, an increase of 0.9 percentage points year-on-year and an increase of 3 million yuan in profits.
In 2011, Shanxi Coking implemented a 100,000-ton/year benzene hydrogenation production process and equipment improvement project, and improved the technology and process of the polymerization inhibitor filling method, xylene distillation tower, and extraction agent replacement device. The efficiency has overcome the influence of steam pressure fluctuations on the recovery of light benzene and achieved the self-purging of the non-stopping replacement of the extractant and the polymer of the gravity-removal tray tray. The total refining rate of benzene products reached 98.6% and the device achieved continuous operation.
