Abstract:

Introduced diesel hydrotreating unit of SINOPEC Qingdao Petrochemical company at the end of the operation of the catalyst, the product of the vehicle is modified by the national standards for the national standards, and the sulfur content in the diesel is performed under the condition of 50 μg/g, diesel hydrogenation unit according to the actual operation, through optimization of production plan, optimizing the ratio of raw materials and raw material properties, improve hydrogen partial pressure, stable operation, predict summary of efforts, before Catalyst replacement makes full use of the catalyst activity, The production task of the state Ⅳ diesel oil was completed.

Key words: diesel, hydrotreating unit, national IV emission standard, process optimization
