Abstract

1. Способ двухколонной пропановой деасфальтизации нефтяных остатков в двух последовательно соединенных экстракторах, по которому сырье смешивают с жидким пропаном, смесь охлаждают и вводят в первый экстрактор для разделения на раствор деасфальтизата I и асфальтовую фазу, отличающийся тем, что сырье смешивают с частью пропана, с вводом охлажденной смеси на несколько ступеней выше нижнего ввода оставшегося количества пропана, раствор деасфальтизата I без нагрева наверху первого экстрактора направляют вниз второго экстрактора, в котором за счет повышения температуры верха разделяют на рисайкл и раствор деасфальтизата II, с регенерацией из него пропана путем постепенного нагрева и снижения давления в испарителях пропана до давления в системе конденсации пропана, с дополнительным нагревом раствора деасфальтизата II из последнего испарителя пропана до 240-250°C, с возвратом рисайкла насосом наверх первого экстрактора, с подачей полученных продуктов в отпарные колонны, работающие без подачи в них водяного пара.2. Температура верха второго экстрактора не превышает 55°C.1. The method of two-column propane deasphalting of oil residues in two series-connected extractors, in which the raw material is mixed with liquid propane, the mixture is cooled and introduced into the first extractor for separation into a solution of deasphalting agent I and the asphalt phase, characterized in that the raw material is mixed with a part of propane, with by introducing the cooled mixture several steps above the lower input of the remaining amount of propane, the solution of deasphalting agent I without heating at the top of the first extractor is sent down to the second extractor, in which and due to the increase in the temperature of the top, the deasphalting solution II is divided into a risicl and a solution of deasphalting agent II, with propane regenerating from it by gradually heating and reducing the pressure in the propane evaporators to a pressure in the propane condensation system, with additional heating of the deasphalting solution II from the last propane evaporator to 240-250 ° C , with the return of the risiclele by the pump to the top of the first extractor, with the supply of the products obtained in stripping columns operating without supplying water vapor to them. 2. The top temperature of the second extractor does not exceed 55 ° C.
