Description

Насто щее изобретение касаетс  способа обезмасливани  белых вод, получающихс  при щелочной очистке нефт ных масел.The present invention relates to a method for de-oiling white waters resulting from alkaline refining of petroleum oils.

В литературе зже описаны способы обезмасливани  белых вод с применением раствора едкого натра дл  разрущени  эмульсии и керосинового щелочного отброса в качестве обезмасливающего реагента. Недостатком описанных способов  вл етс  очень большой расход керосинового щелочного отброса, ресурсы которого весьма ограничены. Расход этого реагента может быть значительно сокращен, если процесс обезмасливани  вести по способу, согласно насто щему изобретению, отличительной особенностью которого  вл етс  применение в качестве деэмульгатора концентрированного раствора едкого натра крепостью не ниже 16° Вё.Methods for de-oiling white waters using caustic soda solution to destroy the emulsion and alkaline kerosene waste as a deoiling agent are described in the literature. The disadvantage of the described methods is the very high consumption of kerosene alkaline garbage, the resources of which are very limited. The consumption of this reagent can be significantly reduced if the de-oiling process is carried out according to the method according to the present invention, the distinguishing feature of which is the use of a concentrated sodium hydroxide solution as a demulsifier with a strength of at least 16 ° Be.

Предлагаемый способ осуществл етс  следующим образом.The proposed method is carried out as follows.

Масл ные щелочные отбросы (белые воды), при температуре 70 - 80°, подвергаютс  обработке раствором едкого натра крепостью не ниже , до разрущени  эмульсии; концом реакции  вл етс  изменение цвета обрабатываемых белых вод (почернение ). Расход раствора NaOH при указанном процессе колеблетс  от 5 до на белые воды и определ етс  содержанием органики (нафтеновых кислот и минеральных масел) в белых водах. Обработанные таким образом белые воды отстаиваютс  без подогрева 10-12 часов, после чего раздел ютс  на два сло : верхний- масло с незначительным количеством мыл (1--0,) и нижний - щелочный раствор мыл с содержанием почти всех нафтеновых кислот, наход щихс  в исходных белых водах. При этом около , масла (от исходного его содержани  в белых водах) выдел етс  в верхний слой. Масло откачиваетс  в другую емкость, где подогреваетс  до температуры 80° дл  отделени  мыл, после чего используетс  по своему назначению (как целевой продукт - дестиллат соответствующего масла или черна  сол рка); отстоенные от масла мыла присоедин ютс  к щелочному раствору мыл. Щелочный раствор мыл подвергаетс  вторичной обрабЬтке крепким раствором NaOH крепостью не ниже 16°Вё в количестве от 3 до на белые воды (в зависимости от содержани  органики) дл  концентрации мыл иOil alkaline wastes (white waters), at a temperature of 70 - 80 ° C, are treated with a solution of caustic soda with a strength not lower than before the destruction of the emulsion; The end of the reaction is a change in the color of the treated white waters (blackening). The consumption of the NaOH solution in this process ranges from 5 to white waters and is determined by the organic content (naphthenic acids and mineral oils) in the white waters. The white waters treated in this way are settled without preheating for 10–12 hours, after which they are separated into two layers: top oil with an insignificant amount of soaps (1-0), and the bottom alkaline solution of soaps containing almost all naphthenic acids in the original white waters. At the same time, about oil, (from its initial content in white waters) is released into the upper layer. The oil is pumped to another tank, where it is heated to a temperature of 80 ° to separate the soaps, after which it is used for its intended purpose (as the target product is the distillate of the corresponding oil or black salt); separated from the soap oil are attached to an alkaline solution of soaps. The alkaline solution of soaps is subjected to secondary treatment with a strong solution of NaOH with a strength not lower than 16 ° Vy in an amount of from 3 to white water (depending on the organic content) for the concentration of soaps and
