Description
Изобретение относитс к нефтепереработке , в частности подготовке нефти.The invention relates to refining, in particular the preparation of oil.
Известен способ обезвоживани и обессоливани нефти путем введени в нее ней оногенных деэмульгаторов, таких как диссольван 4411. Однако такие деэмульгагоры имеют различную эффективность в зависимости от типа перерабатываемой нефтги, кроме того, дл их производства необходимы большие количества окиси этилена и пропилена .There is a known method of dehydrating and desalting oil by introducing onogenic demulsifiers, such as dissolvan 4411, into it. However, such demulsors have different efficiencies depending on the type of oil being processed, in addition, large quantities of ethylene oxide and propylene are needed to produce them.
Целью изобретени вл етс расширение ассортимента доступных и эффективных деэмульгаторов. Дл этого предлагаетс в качестве деэмульгатора использовать продукт конденсации окиси этилена с полимерами этин лена и винилацетата. Содержание окиси этиле на в деэмульгаторе составл ет ЗО-80%. Раоход предлагаемых деамульгаторов 0,003-О,О0The aim of the invention is to expand the range of affordable and effective demulsifiers. To this end, it is proposed to use the condensation product of ethylene oxide with the polymers of ethylene oxide and vinyl acetate as a demulsifier. The content of ethyl oxide on the demulsifier is 30%. Rauhod proposed demulsifying agent 0.003-O, O0
Пример, ибезвоживание ромашкинской нефти деэмульгатором - оксиэтилированным полимером этилена и винилацетата.Example, and the dehydration of chamomile oil by demulsifier - ethoxylated polymer of ethylene and vinyl acetate.
К эмульсии нефть-вода приливают 0,ООЗ деэмульгатора и перемешивают 15 мин. Обработанную эмульсию термостатируют в течение 4 ч при 60 С, количество выделившейс воды замер ют. За деэмульгируюшую активность примен ют отношение количества вь епившейс воды к обшему содержанию воды в нефти в процентах.To the oil-water emulsion, 0 is poured, the demulsifier OPC and stirred for 15 minutes. The treated emulsion was thermostatic for 4 hours at 60 ° C, the amount of released water was measured. For the demulsifying activity, the ratio of the amount of saturated water to the total water content in oil is used as a percentage.
Деэмульгирующа активность рекомендуемого полимера составл ет 80-90%, аналогичные результаты показал и импортный высокоэффективный деэмульга тор диссоль- ван 4411.The demulsifying activity of the recommended polymer is 80-90%, and the imported high performance dissolving dissolve 4411 showed similar results.
