Title: (JA) パラフィンの精製方法および精製装置
Abstract:
(JA)

炭素数2〜6のパラフィンおよび炭素数2〜6のオレフィンを含む原料からパラフィンを精製するための方法は、吸収塔1において、所定の温度および圧力下で銀イオン含有溶液(吸収液)に原料を接触させて、吸収液に原料中のオレフィンを優先的に吸収させつつ当該吸収液に吸収されなかった非吸収ガスを回収する第1工程と、放散塔2において、所定の温度および圧力下で上記第1工程を経た吸収液からガス成分を放散させて排出する第2工程とを含む。第1工程と第2工程との間で吸収液を循環させながら、第1工程と第2工程とが並行して連続的に行われる。
