Changyi Petrochemical’s 1.8-million-ton diesel hydrogenation modification unit successfully went into operation on October 10, yielding qualified products. The operation marks that the company’s diesel products meet the latest national standards on pollution emission.
The unit began construction in August 2013; finished interim delivery on July 17, 2014; and went into run-up preparation on August 10. It managed to see smooth operation of the 90-ton-per-hour solvent reclamation unit, the 240,000-ton-per-year product purification unit and the 1.8-million-ton diesel hydrogenation modification unit after more than two months of efforts by Changyi Petrochemical’s leadership and personnel from the company’s operation and project departments, as well as Sinopec Fourth Construction Co.
All personnel put in extra hours to purge the pipeline and test air impermeability during preparation. Furnace heating, catalyst loading, secondary air impermeability work, and feeding adjustment were all completed. At the moment, the unit is running smoothly, and various technical indexes are in line with the design requirements.
The diesel hydrogenation unit was designed by Sinopec’s Luoyang Petrochemical Engineering Corporation and is able to produce 1.84 million tons of standard diesel every year. It will help raise Changyi Petrochemical’s product quality, optimize its product mix, diversify its products, and increase the company’s profitability and anti-risk capability. At the same time, the unit will play a positive role in upgrading oil product quality and strengthening local oil product supply. It paves the way for the company to develop products with higher standards in the future.
