OIL REFINING PLANT Russian patent published in 2002 - IPC

FIELD: oil refining at production of distillate fractions to be used as fuel and bottom. SUBSTANCE: proposed plant includes furnace for heating oil which is connected with supply zone of atmospheric rectifying column and second rectifying column. Bottom of first rectifying column is connected with supply zone of second atmospheric column whose bottom is connected with mixer of second organomineral carrier. Mixture enters reactor through heating furnace; bottom of reactor is connected with high-pressure separator. Tops of reactor and high-pressure separator are connected with supply zone of first atmospheric column. Bottom of high-pressure separator is connected with cold separator whose overflow enters second atmospheric column. EFFECT: possibility of obtaining distillate fraction at high yield. 1 dwg
