Description
Изобретение относитс к технике транспортировани нефти трубопроводным транспортом и может быть использовано при подготовке высоков зких нефтйй к транспортированию.The invention relates to a technique for transporting oil by pipeline and can be used in the preparation of highly viscous oils for transportation.
Цель изобретени - повышение эффективности подготовки нефти путем снижени в зкости за счет обработки т желой нефти в течение 25ч спиртовым раствором щелочи при соотношении нефть раствор щелочи 1 2,5-5 и затем п тикратным количеством слабого раствора сол ной кислоты рН 3,5- 4.0The purpose of the invention is to increase the efficiency of oil treatment by reducing the viscosity by treating heavy oil for 25 hours with an alcoholic alkali solution at an oil ratio of alkali solution 1 2.5-5 and then with fivefold amount of a weak hydrochloric acid solution pH 3.5-4.0
Способ осущест вл ют следующим образомThe method is as follows.
Пример 1 В нефть с кинематической в зкостью 510 сСт добавл ют спиртовой раствор щелочи в соотношении 1 5 Смесь интенсивно перемешиваетс в течение 2,5 ч, Затем добавл ют п тикратный обьем слабого раствора HCI рН 5 Нефть и водна фаза расслаиваютс , водный раствор отдел ют .Example 1 Into an oil with a kinematic viscosity of 510 cSt, an alcoholic alkali solution is added in a ratio of 1 to 5. The mixture is vigorously stirred for 2.5 hours. .
Пример 2. Берут нефть и спиртовой раствор щелочи в соотношении 1:5 и сол ную кислоту рН 4 В зкость снизилась в 2 раза.Example 2. A 1: 5 oil and alcohol alkaline solution and hydrochloric acid pH 4 were taken. The viscosity decreased by a factor of 2.
Пример 3. Берут нефть и спиртовой раствор щелочи в соотношении 1 5, рН сол ной кислоты равен 3,5 Снижение в зкости достигает 60%Example 3. Take oil and alcohol solution of alkali in the ratio of 1 to 5, the pH of hydrochloric acid is 3.5. The decrease in viscosity reaches 60%.
Пример 4 Берут нефть и спиртовой раствор щелочи в соотношении 1.10, рН сол ной кислоты равен 4 В зкость нефти снизилась на 32%Example 4 An oil and alcohol solution of alkali is taken in a ratio of 1.10, the pH of hydrochloric acid is 4. The viscosity of oil has decreased by 32%.
Пример 5 Берут нефть и спиртовой раствор щелочи в соотношении 1 2,5, рН сол ной кислоты равен 4 Снижение в зкости достигает 39%Example 5 An oil and alcohol solution of alkali in a ratio of 1 to 2.5 is taken, the pH of hydrochloric acid is 4. The decrease in viscosity reaches 39%.
Пример 6 Берут нефть и спиртовой раствор щелочи в соотношении 1 5, рН сол ной кислоты равен 2 5 Снижение в зкости достигает 22%.Example 6 An oil and alcohol solution of alkali is taken in a ratio of 1 to 5, the pH of hydrochloric acid is 2 5. The decrease in viscosity reaches 22%.
Данные приведены в таблицеThe data are given in the table.
Как видно из таблицы, дополнительна обработка нефти слабым раствором сол ной кислоты рН 3.5-4 позвол ет снизить кинематическую в зкость на 60-84% Повышение или снижение рН относительно за вл емого интервала приводит к снижению эффекта.As can be seen from the table, additional processing of oil with a weak solution of hydrochloric acid pH 3.5-4 allows to reduce the kinematic viscosity by 60-84%. Increasing or decreasing the pH relative to the stated interval leads to a decrease in the effect.
