This equipment uses kerosene as raw material. After heat exchange and heating, the raw materials enter the flash tower after heating to a certain temperature. Separate the components of the raw material that are easy to produce. Light liquid non-condensable gas are obtained at the top of the flash tower. The raw materials after flash steaming are reheated and enter the separation tower. After separation, the top of the tower is the 200# solvent oil. The bottom of the tower gets more than 200℃ distillate, according to the actual need to do diesel processing material or to do ore solvent.
Crude oil process route is relatively mature, firstly is “one shed three injection” Then the separation of normal pressure and vacuum pressure, Later according to the specific requirements of the product for different refining requirements.
The product range is relatively wide, mainly: LNG, LPG, naphtha products, gasoline products, kerosene, diesel products, base oil products, Etc. the operation capacity can reach 5 million tons per year.
