Embodiment Construction
[0037] exist figure 1In the process, heavy distillate oil and wax (1) from Fischer-Tropsch synthesis are first mixed with low-temperature oil-washed naphtha (2), then mixed with mixed hydrogen, and passed through the reaction feed / reaction effluent heat exchanger of the refining unit ( 3) Preheating, and then heated to the reaction temperature required by hydrofinishing through the heating furnace (4) and enters the hydrofinishing reactor (5), where reactions such as hydrogenation saturation of olefins and hydrodeoxygenation of oxygenates occur on the reactor bed , the inlet temperature of the lower bed is controlled by cold hydrogen between the beds. The reaction effluent is initially cooled by the heat exchanger (3) and then enters the hot high-pressure separator (6) of the refining unit. The hot high-pressure separator (6) liquid phase enters the hot low-pressure separator (9), the gas phase enters the cold high-pressure separator (7) after being cooled by the air cooler, ...
