FIELD: chemistry.SUBSTANCE: device for purification of liquefied hydrocarbon gases from acidic components includes pipeline 1 of supply of flow of liquid hydrocarbons for purification, connected with evaporation unit 2, which has pipeline 7 of output of flow of liquefied hydrocarbon gases and pipeline 3 of output of gas phase flow, connected with unit 4 of removal of acidic components, provided with pipeline 5 of output of purified gas phase flow. Installation is provided with unit 6 of absorption of gas phase purified flow from unit of removal of acidic components, as well as connected through additionally installed unit 8 of cooling with pipeline 7 of output of flow of liquefied hydrocarbon gases from evaporation unit 2. Absorption unit 6 has pipeline 9 of output of purified flow of liquefied hydrocarbon gases and pipeline 10 of output of undissolved part of gases. Unit 6 of absorption of gas phase purified flow can be connected with pipeline of output of gas phase purified flow from unit 5 of removal of acidic components through additionally installed unit 11 of gas phase washing or through additionally installed unit 17 of gas phase drying.EFFECT: invention makes it possible to purify flow of liquefied hydrocarbon gases from acidic components and obtain purified hydrocarbons in liquid form.1 dwg, 1 ex |
