Description
Известный способ обессоливани и обезвоживани нефти состоит в использовании деэмульгаторов - поверхностно-активных веществ . В предлагаемом способе, с целью повыше- 5 ни эффективности обессоливани и обезвоживани т желых высокосернистых нефтей, в качестве деэмульгатора примен ют продукт конденсации уротропина и моноэтаноламина. Дл получени деэмульгатора в реактор за- 10 гружают 23% технического уротропина и 77% мопоэтаноламина, которые при перемешивании нагревают до 80-80° С. Затем к ним добавл ют 10% катализатора CuS04 и 17% HoSO и продолжают нагрев 6 час до 170° С. По ист е- 15 чении указанного времени температуру реакционной смеси поднимают до 180-190° С и выдерживают ее при этой температуре 30 мин. Полученный продукт охлаждают до 80° С и выгружают. Он представл ет собой сиропооб- 20 разную жидкость темно-бурого цвета, хорошо растворимую в воде. Испытани деэмульгируюш ,ей способности деэмульгатора проводили при термохимической обработке нефтей. Сравнительные данные эффективности различных 25 деэмульгаторов прп термохимическом обессоливанпи бугурусланской нефти показаны в таблице. той серноводской нефти показали, что он ает хорошие результаты при подаче его и в лектрическую ступень обессоливани при птимальном расходе 5 г/т нефти. Степен.ь обессоливани серноводской нефти 90-94%. Предмет изобретени Способ обессоливани и обезвоживани нефти с применением деэмульгаторов, отличающийс тем, что, с целью повышени степени обессоливани и обезвоживани высокосернистых т желых нефтей, в качестве деэмульгатора используют продукт конденсации уротропина и моноэтаноламина.A known method of desalting and dehydrating oil consists in using demulsifiers - surfactants. In the proposed method, in order to increase the efficiency of desalting and dehydrating heavy sour oils, the condensation product of hexamine and monoethanolamine is used as a demulsifier. To obtain a demulsifier, 23% of technical urotropine and 77% of mopoethanolamine are loaded into the reactor, which are heated to 80-80 ° C with stirring. Then 10% of CuS04 catalyst and 17% HoSO are added to them and the heating is continued for 6 hours to 170 ° C. After this time, the temperature of the reaction mixture is raised to 180-190 ° C and maintained at this temperature for 30 minutes. The resulting product is cooled to 80 ° C and unloaded. It is a syrup-like liquid of a dark brown color, well soluble in water. The tests are demulsified, her ability to demulsifier was carried out during thermochemical treatment of oils. Comparative data of the effectiveness of various 25 demulsifiers prp thermochemical desalting of Buguruslan oil is shown in the table. This sernovodsk oil showed that it achieves good results when it is supplied to the electrical desalting stage with a minimum consumption of 5 g / t of oil. The degree of desalting of sernovodsk oil is 90-94%. The subject of the invention is a method for desalting and dehydrating oil using demulsifiers, characterized in that, to increase the degree of desalting and dehydration of sour heavy oils, the product of condensation of hexamine and monoethanolamine is used as a demulsifier.
