Abstract
Description
Изобретение относится к области нефтепереработки и нефтепромысловой химии, в частности к реагентам-нейтрализаторам сероводорода и легких меркаптанов в жидких углеводородных средах, и может быть использовано в нефтедобывающей промышленности.The invention relates to the field of oil refining and oilfield chemistry, in particular to reagents that neutralize hydrogen sulfide and light mercaptans in liquid hydrocarbon media, and can be used in the oil industry.
Сероводород и легкие меркаптаны являются одними из самых опасных и нежелательных компонентов в нефтях и газоконденсатах. Это обусловлено их высокой токсичностью по отношению к человеку и живым организмам, а также высокой коррозионной активностью, что негативно отражается на технологическом оборудовании, используемом в нефтедобыче. Поэтому содержание сероводорода и легких меркаптанов в товарной нефти строго ограничено и регламентируется по ГОСТ Р 51858-2002 с изм. №1 от 01.01.2006 г., согласно которому содержание сероводорода в товарной нефти должно составлять не более 20 ppm, а легких метил- и этилмеркаптанов в сумме не более 40 ppm. При этом в добываемой нефти содержание сероводорода и легких меркаптанов может варьироваться от нескольких десятков до нескольких тысяч ppm. Поэтому задача снижения содержания сероводорода и легких меркаптанов является актуальной для нефтедобывающих предприятий. Одним из перспективных направлений решения данной проблемы является удаление сероводорода и легких меркаптанов непосредственно в нефти, путем добавления реагентов нейтрализаторов.Hydrogen sulfide and light mercaptans are among the most dangerous and undesirable components in oils and gas condensates. This is due to their high toxicity to humans and living organisms, as well as high corrosive activity, which negatively affects technological equipment used in oil production. Therefore, the content of hydrogen sulfide and light mercaptans in commercial oil is strictly limited and is regulated according to GOST R 51858-2002 as amended. No. 1 of 01/01/2006, according to which the hydrogen sulfide content in commercial oil should be no more than 20 ppm, and light methyl and ethyl mercaptans in total no more than 40 ppm. At the same time, the content of hydrogen sulfide and light mercaptans in produced oil can vary from several tens to several thousand ppm. Therefore, the task of reducing the content of hydrogen sulfide and light mercaptans is relevant for oil producing enterprises. One of the promising directions for solving this problem is the removal of hydrogen sulfide and light mercaptans directly from oil by adding neutralizing reagents.
Из уровня техники известен нейтрализатор сероводорода, включающий уротропин, формалин, а также дополнительно водорастворимую соль карбоновой кислоты, преимущественно формиат и/или ацетат щелочного металла и метанол (RU 2470988, кл. МПК C10G 29/20, опубл. 27.12.2012). Указанный состав позволяет достигать высокой степени очистки сероводорода до 98%.A hydrogen sulfide neutralizer is known from the prior art, including methenamine, formalin, and also an additional water-soluble salt of a carboxylic acid, predominantly formate and/or alkali metal acetate and methanol (RU 2470988, IPC class C10G 29/20, published 12/27/2012). This composition makes it possible to achieve a high degree of hydrogen sulfide purification up to 98%.
Недостатком данного состава нейтрализатора является применимость только для удаления сероводорода, при этом нет данных об эффективности применения реагента для удаления одновременно сероводорода и легких меркаптанов.The disadvantage of this neutralizer composition is its applicability only for the removal of hydrogen sulfide, while there is no data on the effectiveness of using the reagent for simultaneously removing hydrogen sulfide and light mercaptans.
Из уровня техники известен способ очистки нефти, нефтепродуктов и газоконденсата от сернистых соединений путем их обработки смесью азотной кислоты с железом (RU 2134285, кл. МПК C10G 17/02, C10G 29/04, опубл. 10.08.1999). Указанный способ позволяет удалять до 100% меркаптановой серы.The prior art knows a method for purifying oil, petroleum products and gas condensate from sulfur compounds by treating them with a mixture of nitric acid and iron (RU 2134285, IPC class C10G 17/02, C10G 29/04, publ. 08/10/1999). This method allows you to remove up to 100% of mercaptan sulfur.
Недостатком данного способа является применение больших объемов азотной кислоты высокой концентрации, что вызывает проблемы с утилизацией отработанной кислотыThe disadvantage of this method is the use of large volumes of high concentration nitric acid, which causes problems with the disposal of waste acid
Из уровня техники известен метод удаления сероводорода из сырой нефти путем добавления вещества, содержащего в своем составе карбонильную группу (US 4909925 (A), кл. МПК C10G 29/20, опубл. 20.03.1990). Указанный метод позволяет с высокой эффективностью удалять сероводород.The prior art knows a method for removing hydrogen sulfide from crude oil by adding a substance containing a carbonyl group (US 4909925 (A), IPC class C10G 29/20, published 03/20/1990). This method makes it possible to remove hydrogen sulfide with high efficiency.
Недостатком данного способа является применимость для удаления только сероводорода, при этом отсутствуют данные о возможности его применения для удаления легких меркаптанов.The disadvantage of this method is its applicability for the removal of hydrogen sulfide only, while there is no data on the possibility of its use for the removal of light mercaptans.
Из уровня техники известен метод удаления сероводорода путем контакта с реагентом, представляющим собой продукт реакции гетероциклического альдегида (такого как фурфурол) с первичным амином (US 5266185 (A), кл. МПК C07D 307/14; C07D 307/52; C07D 333/20; C09K 8/54; C10G 29/20; C10L 1/228; C10L 1/232; C10L 1/24, опубл. 30.11.1993). Метод позволяет с высокой эффективностью удалять сероводород в том числе в тяжелых нефтяных фракциях.The prior art knows a method for removing hydrogen sulfide by contact with a reagent that is a reaction product of a heterocyclic aldehyde (such as furfural) with a primary amine (US 5266185 (A), IPC class C07D 307/14; C07D 307/52; C07D 333/20 ; C09K 8/54; C10G 29/20; C10L 1/228; C10L 1/232; C10L 1/24, publ. 11/30/1993). The method makes it possible to remove hydrogen sulfide with high efficiency, including in heavy oil fractions.
Недостатком данного метода является применимость только для удаления сероводорода, при этом отсутствуют сведения о возможности применения данного метода для удаления легких меркаптанов.The disadvantage of this method is its applicability only for the removal of hydrogen sulfide, while there is no information about the possibility of using this method for the removal of light mercaptans.
Наиболее близким к заявленному нейтрализатору является поглотитель сероводорода, включающий амидины и полиамидины (US 5223127 (A), кл. МПК: C09K 8/54; C10G 29/00; C10G 29/20; C10L 1/228; C10L 1/232; C23F 11/14, опубл. 29.06.1993). Указанные реагенты позволяют с высокой эффективностью снижать содержание сероводорода в жидких углеводородных средах. Недостатком указанного способа является ограниченная применимость только для удаления сероводорода.The closest to the claimed neutralizer is a hydrogen sulfide absorber, including amidines and polyamidines (US 5223127 (A), IPC class: C09K 8/54; C10G 29/00; C10G 29/20; C10L 1/228; C10L 1/232; C23F 11/14, publ. 06/29/1993). These reagents make it possible to highly effectively reduce the hydrogen sulfide content in liquid hydrocarbon media. The disadvantage of this method is its limited applicability only for the removal of hydrogen sulfide.
Таким образом, все известные реагенты-поглотители сероводорода и легких меркаптанов обладают рядом недостатков, в частности использованием больших количеств концентрированных кислот или ограниченным применением только для удаления сероводорода.Thus, all known reagents that absorb hydrogen sulfide and light mercaptans have a number of disadvantages, in particular the use of large quantities of concentrated acids or limited use only for the removal of hydrogen sulfide.
Технический результат, на получение которого направлено изобретение, заключается в расширении арсенала реагентов-нейтрализаторов сероводорода и легких меркаптанов, в том числе, без использования больших количеств концентрированных кислот и позволяющих удалять более 50% сероводорода и легких меркаптанов.The technical result to which the invention is aimed is to expand the arsenal of reagents that neutralize hydrogen sulfide and light mercaptans, including without the use of large quantities of concentrated acids and allowing the removal of more than 50% of hydrogen sulfide and light mercaptans.

Использование нейтрализатора, содержащего органическую основу и кислоту, выступающую в роли катализатора и ускоряющую процесс реакцию между органической основой и сероводородом и/или легкими меркаптанами, обеспечивает возможность достижения заявленного технического результата в виде расширения арсенала реагентов-поглотителей сероводорода и легких меркаптанов. При этом существенно улучшены результаты по сравнению с аналогами, так как уже при комнатной температуре удается достичь конверсии сероводорода и легких меркаптанов 50-100% в зависимости от дозировки и состава. The use of a neutralizer containing an organic base and an acid that acts as a catalyst and accelerates the reaction between the organic base and hydrogen sulfide and/or light mercaptans makes it possible to achieve the stated technical result in the form of expanding the arsenal of hydrogen sulfide and light mercaptan scavenger reagents. At the same time, the results are significantly improved compared to analogues, since already at room temperature it is possible to achieve a conversion of hydrogen sulfide and light mercaptans of 50-100%, depending on the dosage and composition .
Согласно изобретению, поглотитель получен путем смешивания указанных компонентов в указанных соотношениях любым способом, обеспечивающим равномерное смешивание составляющих.According to the invention, the absorbent is obtained by mixing the specified components in the specified ratios in any way that ensures uniform mixing of the components.
При использовании реагента-поглотителя сероводорода и легких меркаптанов, по настоящему патенту, реагент добавляют в нефть любым из известных способов.When using a reagent-scavenger for hydrogen sulfide and light mercaptans, according to this patent, the reagent is added to oil by any of the known methods.
Анализ уровня техники показал отсутствие технических решений, аналогичных заявляемому по совокупности признаков, и с наличием вышеуказанных свойств, что позволяет сделать вывод о соответствии заявляемого решения критериям «новизна» и «изобретательский уровень».An analysis of the level of technology has shown the absence of technical solutions similar to the claimed one in terms of the totality of features and the presence of the above properties, which allows us to conclude that the claimed solution meets the criteria of “novelty” and “inventive step”.
В таблице 1 приведены примеры, иллюстрирующие осуществление изобретения и получаемые результаты. Полученные составы испытывали на образце нефти с исходным содержанием сероводорода 900 ppm, метилмеркаптана 300 ppm и этилмеркаптана 2400 ppm. Определение активности проводили путем добавления реагента-поглотителя в образец нефти. Образец нефти, содержащий реагент, перемешивали при комнатной температуре в течение 2 ч. Дозировку рассчитывали исходя из массовых соотношений, соответственно:Table 1 shows examples illustrating the implementation of the invention and the results obtained. The resulting compositions were tested on an oil sample with an initial content of hydrogen sulfide of 900 ppm, methyl mercaptan of 300 ppm and ethyl mercaptan of 2400 ppm. Activity determination was carried out by adding a scavenger reagent to an oil sample. The oil sample containing the reagent was stirred at room temperature for 2 hours. The dosage was calculated based on the mass ratios, respectively:
- реагент: сумма сероводорода и легких меркаптанов - от 4:1 до 7:1,- reagent: sum of hydrogen sulfide and light mercaptans - from 4:1 to 7:1,
Конверсию сероводорода, метил- и этилмеркаптана рассчитывали как отношение разницы между исходным и остаточным содержанием к исходному содержанию сероводорода, метил- или этилмеркаптана, умноженному на 100%.The conversion of hydrogen sulfide, methyl and ethyl mercaptan was calculated as the ratio of the difference between the initial and residual content to the initial content of hydrogen sulfide, methyl and ethyl mercaptan, multiplied by 100%.
