Description

Деасфальтизаци  масл ных гудронов и концентратов осуществл етс  в промышленности с применением в качестве растворител  пропана высокой степени частоты при соотношении по весу 4 : 1 между растворителем и сырьем.Oil tars and concentrates are deasphalted in industry using high-frequency propane as a solvent, with a ratio by weight of 4: 1 between the solvent and the raw material.

Большое количество расходуемого в этом процессе жидкого пропана требует установки испарителей с большой поверхностью нагрева и больших расходов пара и охлаждающей воды дл  регенерации пропана.The large amount of liquid propane consumed in this process requires the installation of evaporators with a large heating surface and high consumption of steam and cooling water to regenerate propane.

Описываемый новый способ деасфальтизацип основан на применемии в качестве растворител  неожиженных сжатых углеводородных газоп, которые под давлением 100-150 атм хорошо раствор ют углеводородную часть сырь , но не раствор ют его асфальтово-смолистых компонентов .The described new method of de-asphalt-freezing is based on using as solvent a non-liquefied compressed hydrocarbon gas, which, under a pressure of 100-150 atm, dissolves well the hydrocarbon part of the raw material, but does not dissolve its asphalt-resinous components.

При снижении давлени  до 50 атм из газового раствора выпадают деасфальтизированные продукты и газовый растворитель регенерируетс .As the pressure decreases to 50 atm, deasphalted products fall out of the gas solution and the gas solvent is regenerated.

Деасфальтизаци  газовым растворителем применима дл  различных видов нефт ного сырь  от нефтей до гудронов и крекинг - остатка.Gas solvent deasphalting is applicable to various types of crude oil from oils to tars and cracking residue.

На чертеже изображена принципиальна  технологическа  схема процесса деасфальтизации газовым растворителем.The drawing shows a process flow diagram of the deasphalting process with a gas solvent.

В смеситель / насосом 2 подают сырье и дожимающим компрессором 3 газ-растворитель при количественном их соотношении по весу от 1 : 2 до 1 : 3. Углеводородна  часть сырь  при этом раствор етс  в газе, а асфальтово-смолиста  часть сырь  в виде битума или сухого порошка выпадает на дно смесител . Газовый раствор из смесител  / вывод т в сепаратор 4 с редуцированием его давлени  до 50 атм при одинаковой температуре в смесителе и сепараторе, котора  должна быть несколько выше критической температуры газа-растворител .Raw materials and a booster compressor 3 are supplied to the mixer / pump 2 with a solvent gas in a quantitative ratio by weight from 1: 2 to 1: 3. The hydrocarbon part of the raw material is dissolved in the gas, and the asphalt-resinous part of the raw material is in the form of bitumen or dry the powder falls to the bottom of the mixer. The gas solution from the mixer / outlet to the separator 4 with the reduction of its pressure to 50 atm at the same temperature in the mixer and the separator, which should be slightly above the critical temperature of the solvent gas.

Дл  пронан-пропиленовой фракции, например, температура в смесителе и сепараторе должна быть равной 100°.For pronane-propylene fraction, for example, the temperature in the mixer and the separator must be 100 °.

Снижение давлени  в сепараторе вызывает выпадение из газового раствора деасфальтизированного продукта и одновременно регенерацию газового растворител , который поступает в дожимающий компрессор и далее в смеситель дл  доасфальтизации новых порций сырь .Reducing the pressure in the separator causes the deasphalted product to fall out of the gas solution and at the same time regenerate the gas solvent that enters the booster compressor and then into the mixer to asphalt the new batches of raw materials.

Битумпа  часть сырь  из смесител  и деасфальтизированный продукт из сепаратора непрерывно отвод тс  дл  выделени  из них остатков растворенного газа, составл ющих дл  битумов 0,5/о и дл  деасфальтизированного продукта 2%. Процесс ведут непрерывно с циркул цией газа, первоначально введенного в установку.The bituminous part of the raw material from the mixer and the deasphalted product from the separator are continuously drained to extract residual gas from them, comprising 0.5 / o for the bitumen and 2% for the deasphalted product. The process is conducted continuously with the circulation of the gas initially introduced into the installation.

Предмет изобретени Subject invention

Способ обессмоливани  нефт ного сырь  с использованием растворител , отличающийс  тем, что, с целью повыщени  эффективности процесса, в качестве растворител  примен ют сжатые до 100- 150 атм. углеводородные газы, в количестве 2-3 части по гзесу на 1 часть нефт ного сырь .A method for de-tarting petroleum feedstock using a solvent, characterized in that, in order to increase the efficiency of the process, compressed to 100-150 atm is used as the solvent. hydrocarbon gases, in the amount of 2-3 parts of oil per 1 part of crude oil.
