A method of obtaining greater amounts of distillate feedstocks from the heavy gasoil recovered by vacuum distillation of the products of thermal cracking of petroleum resids was examined. At the Novo-Ufa Petroleum Refinery, a two-furnace thermal cracking unit was reconstructed, adding a vacuum section for distillation of the cracked tar. A simplified flow plan of this unit is shown. Vacuum resid from atmospheric-vacuum tubestill units is heated in double-pipe heat exchangers, using heat from the gasoil and cracked tar. The new method makes it possible to curtail production of boiler fuel, expand the resources of feed, and improve the quality of petroleum coke.
