600,000 tons per year of diesel hydroprocessing; no dew point adjustment is performed, and the catalyst used is the standard DN3100 type. The reactor temperature is 275 at the inlet and 335 at the outlet, with good performance
Ours is 500,000 tons per year. We use a K115 catalyst, and the temperature rise is around 90 degrees I think
1 million tons of diesel hydrorefining, using catalyst HCK; it has been in use for 3 years, with a temperature rise of 30–40°C. Both desulfurization and denitrification are very effective, with rates generally exceeding 90%; however, adjustments should be made based on the quality of the product, to avoid excessive quality levels
200,000 tons per year high-pressure hydrogenation unit for the hydrogenation of vacuum distillate oil; the catalysts used are FF-26, FDW-3, and FV-20 developed by Fushun Petrochemical Research Institute. The inlet temperature of the first reactor is 330 degrees, with a temperature rise of 40 degrees. The three reactors are connected in series for a single pass through the process; the space velocity is 0.16, and the hydrogen-to-oil ratio is 1000. The desulfurization and denitration efficiency is around 96%
Our design capacity is 300,000 tons per year; the catalysts used are FH-98 and FCI8 from Shunpetro Research Institute. The total designed temperature rise is 86°C, at 295/327°C. The plant has not yet been put into operation!
400w/Y diesel hydrogenation catalysts, FH-UDS and 3963, are now in operation
Fujian United Petrochemical: 2.3 million tons/year of hydrogenation processing using catalyst FC-12; 2.1 million tons/year of hydrocracking using catalysts FC-12/FF-16. Construction is in progress, with operations set to begin by the end of this year.
The range of topics for discussion is too broad. It should be divided into units such as hydrorefining and hydrocracking; furthermore, when discussing the desulfurization and denitration effects of catalysts, reaction pressure and the properties of the feedstock need to be taken into account.
150,000 tons per year; the catalyst used is FH-98 from Shunpetro Research Institute. The temperature rise is between 50-70, and the reaction temperature ranges from 270-290. Depending on the properties of the oil, the product meets national standards. The effect is okay.
