　　Abstract

　　This design is the preliminary design of the section of 190000 t/a tar distillation in tar processing factory and mainly introduces the distillation process.According to comparing the existing process, chosing the domestic application of more and more mature tar distillation tower is two columns continuous distillation of coal tar. First of all, do the material balance and heat balance calculation，design calculation and equipment selection for he main equipment, and determine the diameter and height of the tower, and do the tower board calculation and  check design of fluid mechanics；distillation tower were mechanically designed and strengthly checked；finally，the process conditions；distillate tower mechanical design and The strength check; Finally, non-process conditions.By Auto-CAD,drawing piping and instrument diagram，the distillation column chart and workshop layout.

　　The results of the design of the main equipment is as follows.Cylindrical tube type furnace is 3.5 million kcal/h, the diameter of evaporator is 1600mm, the diameter of two sections of evaporator is 2400mm, and the diameter of fractions tower is 1800mm, whose height is 28000mm, the number of whose plate is 47, and the diameter of anthraquinone tower is 1800mm, the number of whose tower plate is 21 and whose height is 17000mm, and the cooler area of a condensation heat and the limonene condensation heat are respectively 72m2 and 296m2,and the heat transfer area of anthracene oil submerged type cooler is 12m2 etc.
