Recently, Shanghai Petrochemical Refinery No. 2 refinery joint unit successfully used the old equipment, two months to increase production of 8640 tons of jet fuel, equivalent to an increase of 43.2 million yuan in economic benefits, to achieve the efficient use of resources and equipment re-win.
Due to the reaction system without temperature rise, the heating furnace heating bottleneck, fractional distillation system heat regulation space is small and other constraints, Shanghai Petrochemical 2 # 1 diesel refinery hydrogenation unit repeatedly encountered aviation quality unqualified problems, and the device Processing capacity has also been affected to a certain extent, had to run at low load.
In order to overcome this difficulty, this device specially made a research project and actively communicated with the Design Institute, and finally decided to increase the temperature of the fractionation system, increase the temperature of the fractionation system, reduce the load of the heating furnace and ensure that the qualified coal ship would be qualified by adding a heat exchanger.After many considerations, The device has been selected from the decommissioned 1 # catalytic converter device, after removal of cleaning, forensics, to meet the backup conditions, and put into use on October 12.
According to the statistics, after the old heat exchanger is put into operation, the unit capacity will be increased from 50 tons per hour to 56 tons, the fuel gas will be reduced from 520 to 380 and the steam hour will be increased by 1 ton. An increase of 4320 tons of jet fuel, reducing energy consumption of 0.032 tons of standard oil, an increase of 21.6 million yuan per month revenue.
