Description

В насто щее врем  нафталин и- антрацен выдел ютс  из соответственных фракций каменноугольной смолы кристаллизацией в ваннах в течение б-10 суток . Аппаратура дл  кристаллизации громоздка и требует значительного количества т желого ручного труда.At present, naphthalene and anthracene are separated from the corresponding coal tar fractions by crystallization in baths for b-10 days. The crystallization apparatus is cumbersome and requires a significant amount of heavy manual labor.

Автором найден новый способ выделени  нафталина и антрацена, устран ющий продолжительную кристаллизацию и значительно сокращающий применение ручного труда.The author has found a new method for separating naphthalene and anthracene, which eliminates prolonged crystallization and significantly reduces the use of manual labor.

Сущность найденного автором метода заключаетс  в следующем.The essence of the method found by the author is as follows.

Четкие фракции каменноугольного масла, содержащие нафталин и антрацен в паровой фазе, направл ютс  в полые безнасадочные холодильники непосредственного действи , орощаемые технической водой.The clear fractions of coal oil, containing naphthalene and anthracene in the vapor phase, are sent to hollow, direct-flow, non-condensing refrigerators, irrigated with process water.

В результате происходит практически мгновенное выделение нафталина или антрецена (в соответственных холодильниках ) и конденсаци  масл ных погонов, им сопутствующих.As a result, almost instantaneous release of naphthalene or anthresen (in the respective refrigerators) and condensation of oil shoulder straps associated with them occur.

После разделени  вод ного и дестиллатного сло  в отстойниках сырые фракции кристаллами направл ютс  на фугование , нутчевание, прессование и т. д., водный же слой после охлаждени  в трубчатых холодильниках или градирн х вновь направл етс  на охлаждение погонов.After separation of the water and distillate layer in the settling tanks, the crude fractions are sent to crystals for fugging, grinding, pressing, etc., and the water layer, after cooling in tubular refrigerators or cooling towers, is again sent for cooling the shoulder straps.

Этот принцип может быть также использован в промышленности разгонки первичной смолы, буроугольной смолы, нефти и т. д.This principle can also be used in the distillation industry for primary resin, lignite resin, petroleum, etc.

Одновременно с охлаждением фракций представл етс  возможным производить и мойку их от фенолов, если в качестве охлаждающей жидкости примен ть раствор щелочи.Simultaneously with cooling the fractions, it is possible to produce and wash them from phenols, if an alkali solution is used as a coolant.

Непосредственному охлаждению водой подвергаютс  лищь фракции, содержащие нафталин и антрацен. Другие фракции каменноугольной смолы могут быть охлаждаемы в обычных трубчатых холодильниках.Water fractions containing naphthalene and anthracene are directly cooled with water. Other coal tar fractions may be cooled in conventional tubular refrigerators.

Отделение антраценовой и нафталиновой фракций от охлаждающей воды может производитьс  в отстойниках непрерывного действи , расположенных непосредственно под холодильниками.Separation of the anthracene and naphthalene fractions from the cooling water can be carried out in continuous settling tanks located directly below the refrigerators.

Предмет изобретени .The subject matter of the invention.

Способ выделени  нафталина и антрацена из содержащих их фракций каменноугольной смолы, отличающийс  тем, что получающиес  при разгонке каменноугольной смолы пары фракции.A method of separating naphthalene and anthracene from coal tar fractions containing them, characterized in that the fraction fractions obtained during the distillation of coal tar.
