Abstract
1. Установка очистки этанизированной широкой фракции легких углеводородов от двуокиси углерода, содержащая трубопровод подачи жидкой углеводородной смеси, колонну фракционной перегонки, снабженную снизу выходом очищенного жидкого потока, сверху - выходом газового потока, который соединен с холодильником, выход которого соединен с рефлюксной емкостью, имеющей выходы газа и жидкости, последний соединен через насос с верхом колонны фракционной перегонки, мембранный блок, имеющий выходы пермеата и ретентата, узел подогрева низа колонны фракционной перегонки, отличающаяся тем, что трубопровод подачи жидкой углеводородной смеси соединен через запорно-регулирующую арматуру с трубопроводом, соединяющим выход газового потока из колонны фракционной перегонки с холодильником, и с трубопроводом, соединяющим насос с верхом колонны фракционной перегонки, кроме того, установка дополнительно имеет колонну выделения углеводородов из кислого газа, снабженную в нижней части входом для газового потока, вверху - выходом кислых газов и внизу - выходом жидких углеводородов, при этом вход для газового потока соединен с выходом газа из рефлюксной емкости, выход кислых газов соединен с мембранным блоком, а выход жидких углеводородов соединен через установленный насос с колонной фракционной перегонки, кроме того, колонна выделения углеводородов из кислого газа в верхней части имеет встроенный холодильник, соединенный с источником хладагента.2. Установка очистки этанизированной широкой фракции легких углеводородов от двуокиси углерода по п.1, отличающаяся тем, что выход пермеата соединен с установкой низкотемпературной ко1. Installation for the purification of ethanized wide fraction of light hydrocarbons from carbon dioxide, comprising a liquid hydrocarbon mixture supply pipe, a fractional distillation column equipped with a bottom for the output of the purified liquid stream, and a top for the outlet of the gas stream, which is connected to the refrigerator, the outlet of which is connected to a reflux tank having gas and liquid outlets, the latter is connected through a pump to the top of the fractional distillation column, a membrane unit having permeate and retentate exits, a heating unit for the bottom of the fr distillation distillation, characterized in that the pipeline for supplying a liquid hydrocarbon mixture is connected through shut-off and control valves with a pipeline connecting the outlet of the gas stream from the fractional distillation column with a refrigerator, and with a pipeline connecting the pump to the top of the fractional distillation column, in addition, the installation additionally has a column for the extraction of hydrocarbons from acid gas, provided in the lower part with an inlet for a gas stream, at the top with an outlet of acid gases and at the bottom with an outlet of liquid hydrocarbons, while for the gas stream is connected to the gas outlet from the reflux tank, the acid gas outlet is connected to the membrane unit, and the liquid hydrocarbon outlet is connected via the installed pump to the fractional distillation column, in addition, the column for the separation of hydrocarbons from acid gas in the upper part has a built-in refrigerator connected to source of refrigerant. 2. The installation for the purification of an ethanized broad fraction of light hydrocarbons from carbon dioxide according to claim 1, characterized in that the permeate outlet is connected to a low-temperature unit
