Title (EN) METHOD AND APPARATUS FOR PURIFYING PARAFFIN
(FR) PROCÉDÉ ET APPAREIL DE PURIFICATION DE PARAFFINE
(JA) パラフィンの精製方法および精製装置
Abstract:
(EN) A method of paraffin purification for obtaining purified paraffins from a raw material comprising C2-6 paraffins and C2-6 olefins, the method comprising: a first step in which the raw material is brought into contact with a solution containing silver ions (absorbing solution) in an absorption column (1) at a given temperature and a given pressure to cause the absorbing solution to preferentially absorb the olefins contained in the raw material, and an unabsorbed gas which has not been absorbed in the absorbing solution is recovered; and a second step in which gaseous ingredients are released in a stripping column (2) from the absorbing solution which has undergone the first step, at a given temperature and a given pressure and are discharged.  The first step and the second step are continuously performed in parallel while circulating the absorbing solution through the first step and the second step.
(FR) La présente invention concerne un procédé de purification de paraffines permettant d'obtenir des paraffines purifiées à partir d'une matière première contenant des paraffines C2-6 et des oléfines C2-6, le procédé comprenant : une première étape au cours de laquelle la matière première est amenée en contact avec une solution contenant des ions d'argent (solution absorbante) dans une colonne d'absorption (1) à une température donnée et à une pression donnée de façon à amener la solution absorbante à absorber de préférence les oléfines contenues dans la matière première, et un gaz non absorbé qui n'a pas été absorbé dans la solution absorbante est récupéré ; et une seconde étape au cours de laquelle des composants gazeux sont libérés de la solution absorbante qui a subi la première étape dans une colonne d'extraction (2) et à une température et une pression donnée, puis sont déchargés. La première et la seconde étape sont réalisées en continu et en parallèle pendant que l'on fait circuler la solution absorbante au cours de la première et de la seconde étape.
(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。
