Description

Изобретение относитс  к промысловой обработке и подготовке природного газа и конденсата к транспортировке.This invention relates to field processing and the preparation of natural gas and condensate for transportation.

Известен способ разделени  сжатых газовых смесей, например природных газов, низкотемпературной ректификацией в колонне с предварительным разделением смеси в вихревой камере на холодный и гор чий потоки.A known method for separating compressed gas mixtures, for example, natural gases, by low-temperature distillation in a column, with preliminary separation of the mixture in the vortex chamber into cold and hot streams.

Однако при реализации известного способа не полно используетс  пластова  энерги  газа.However, the implementation of this method does not fully utilize the gas formation energy.

Предлагаемый способ отличаетс  тем, что гор чий поток используют дл  испарени  легких фракций углеводородов нижнего продукта колонны, а холодный - дл  конденсации т желых фракций.The proposed method is characterized in that the hot stream is used to evaporate the light fractions of hydrocarbons of the bottom product of the column, and the cold stream to condense heavy fractions.

Это позвол ет более полно использовать пластовую энергию природного газа.This allows more complete utilization of the natural gas reservoir energy.

На чертеже изображена схема установки. Она включает холодильник /, сепаратор 2, колонну 3, вихревую камеру 4, гор чий поток 5 вихревой камеры, холодный поток 6 вихревой камеры, сепаратор-конденсатор 7, контактные устройства 8, регул тор 9 расхода потоков, ввод абсорбента 10.The drawing shows the installation diagram. It includes a cooler /, separator 2, column 3, vortex chamber 4, hot stream 5 of the vortex chamber, cold stream 6 of the vortex chamber, separator-condenser 7, contact devices 8, flow rate controller 9, introduction of absorbent 10.

Природный газ, пройд  первую ступень сепарации близ скважины, поступает в холодильник 1, где предварительно охлаждаетс  отбензиненным потоком газа. Затем газ поступает в сепаратор 2 дл  отделени  от капель The natural gas, having passed the first separation stage near the well, enters the refrigerator 1, where it is pre-cooled by stripped gas flow. The gas then enters separator 2 to separate from the droplets.

жидкости. Конденсат из сепаратора может транспортироватьс  отдельно или подаватьс  вниз колонны на переработку.fluid. Condensate from the separator can be transported separately or downstream of the column for processing.

Затем поток газа направл етс  в вихревую камеру 4, где он, тер   часть давлени , раздел етс  на холодный и гор чий потоки. Холодный поток под собственным давлением подаетс  в сепаратор-конденсатор 7 колонны 3, где используетс  как хладагент дл  конденсации паров более т желых углеводородов и низкотемпературной сепарации поднимающихс  паров.Then the gas flow is directed to the vortex chamber 4, where it, being rubbed by a part of the pressure, is divided into cold and hot streams. The cold flow under its own pressure is fed to the separator-condenser 7 of the column 3, where it is used as a refrigerant for condensing vapors of heavier hydrocarbons and low-temperature separation of the rising vapors.

Дл  этого можно использовать устройство, совмещающее функции л алюзийного сепаратора и конденсатора пластинчатого типа, имеющего значительные поверхности теплообмена, которое может быть смонтировано непосредственно в колонне. Сепаратор-конденсатор может быть выполнен как вертикального, так и горизонтального типа.To do this, you can use a device that combines the functions of an alluvial separator and a plate-type condenser with significant heat exchange surfaces, which can be mounted directly in a column. The separator-capacitor can be made of both vertical and horizontal type.

Сконденсировавша с  часть паров используетс  дл  орошени  контактных устройств и позвол ет более глубоко осуществл ть процесс отбензинивани .The condensed portion of the vapor is used to irrigate the contact devices and allows for a deeper process of stripping.

Дл  улучщени  отбензинивани  абсорбент подают через ввод 10.To improve the stripping, the absorbent is fed through the inlet 10.

Поток газа, отдавший часть холода, подаетс  затем в колонну в качестве питани .The gas stream, which gave up part of the cold, is then fed to the column as food.

Гор чий поток в виде парожидкой смеси, выйд  из гор чего конца вихревой камеры, попадает в кубовую часть массообменной колонны , где происходит испарение легких фракций и теплообмен между продуктом низа колонны (частична  деметанизаци ).The hot stream in the form of a vapor-liquid mixture leaving the hot end of the vortex chamber enters the bottom part of the mass transfer column, where evaporation of light fractions and heat exchange between the bottom product of the column occurs (partial demethanization).

Разница температур и фракционного состава потоков вверху и внизу колонны позвол ет с помощью монтал ных устройств (тарелок) добитьс  массообмена, углубл ющего процесс отбензинивани .The difference in temperature and fractional composition of the flows at the top and bottom of the column allows using mass-transfer devices (plates) to achieve mass exchange, which deepens the process of topping.

Температура гор чего потока регулируетс  при помощи регул тора 9 расхода гор чего потока.The temperature of the hot stream is regulated by means of the hot flow controller 9.

При использовании регул тора расхода гор чего потока давление на выходе равно или незначительно больше давлени  холодного потока. Это позвол ет применить сепараторконденсатор пластинчатого типа.When using the hot flow controller, the outlet pressure is equal to or slightly greater than the cold stream pressure. This allows the use of a plate-type separator.

Во избежании перегрева гор чий конец вихревой камеры может охлаждатьс  конденсатом в нижней части колонны.In order to avoid overheating, the hot end of the vortex chamber may be cooled by condensate at the bottom of the column.

Инжекционное устройство, установленное на гор чем конце вихревой камеры, повышает эффективность контактировани . При этом происходит распыление продукта гор чим потоком газа.An injection device mounted on the hot end of the vortex chamber increases contact efficiency. When this happens, the product is sprayed with a hot gas stream.

Предлагаемый способ .может быть также проведен в аппарате, где вместо контактных устройств будет примен тьс  инжекци  гор чего и холодного потоков из одной или -нескольких точек.The proposed method can also be carried out in an apparatus where, instead of contact devices, hot and cold flows will be injected from one or several points.

При этом повышаетс  скорость процесса, т. е. увеличиваетс  производительность.This increases the speed of the process, i.e., increases productivity.

При осуществлении описанного способа отбензинивание природного газа практически производитс  в одном аппарате без применени  насосов, испарителей, холодильников, подогревателей за счет утилизации части пластовой энергии природного газа.In the implementation of the described method, natural gas is practically removed in one unit without the use of pumps, evaporators, refrigerators, heaters due to utilization of a portion of the natural gas reservoir energy.
