Abstract
Изобретение относится к области транспортировки высокозастывающих нефтей и позволяет улучшить их реологические свойства. Техническим результатом изобретения является улучшение свойств депрессорной присадки, снижение эффективной концентрации депрессорной присадки, температуры потери текучести и вязкости нефти и нефтепродуктов, подлежащих транспортировке. Технический результат достигается депрессорной присадкой, представляющей собой продукт конденсации сложного эфира полиоксиэтиленсорбитана с ангидридами карбоновых кислот, используемой в количестве 0,005-0,50 мас.%. Техническим результатом изобретения в части способа является его упрощение. Способ получения депрессорной присадки для нефтей и нефтепродуктов конденсацией многоатомного спирта с кислотным органическим компонентом в присутствии катализатора, отличающийся тем, что конденсацию осуществляют в среде апротонного органического растворителя с последующим добавлением разбавителя, а в качестве эфира многоатомного спирта используют сложный эфир полиоксиэтиленсорбитана в виде моно- и триолеата, монолаурата, моностеарата, в качестве кислотного органического компонента - диангидриды алифатических, алициклических, ароматических тетракарбоновых кислот, алкил- и галоидсодержащие диангидриды алициклических тетракарбоновых кислот. Депрессорную присадку используют в виде раствора в смеси апротонного органического растворителя с алкилбензолами и пиридином.The invention relates to the field of transportation of high-melting oils and allows to improve their rheological properties. The technical result of the invention is to improve the properties of the depressant, reducing the effective concentration of the depressant, pour point and viscosity of oil and oil products to be transported. The technical result is achieved depressor additive, which is a condensation product of polyoxyethylene sorbitan ester with carboxylic anhydrides, used in an amount of 0.005-0.50 wt.%. The technical result of the invention in part of the method is to simplify it. A method of producing a depressant for oils and petroleum products by condensation of a polyhydric alcohol with an acidic organic component in the presence of a catalyst, characterized in that the condensation is carried out in an aprotic organic solvent medium followed by the addition of a diluent, and polyoxyethylene sorbitan ester is used as a polyhydric alcohol. trioleate, monolaurate, monostearate, as an acidic organic component - dianhydrides of aliphatic, alicyclic, ap somatic tetracarboxylic acids, alkyl and halide-containing dianhydrides of alicyclic tetracarboxylic acids. A depressant additive is used as a solution in a mixture of an aprotic organic solvent with alkyl benzenes and pyridine.
