Title: (DE) VERFAHREN UND VORRICHTUNG ZUR AUFREINIGUNG VON PARAFFIN
(EN) METHOD AND APPARATUS FOR PURIFYING PARAFFIN
(FR) PROCÉDÉ ET APPAREIL DE PURIFICATION DE PARAFFINE
Abstract: front page image
(EN) A method for purifying a paraffin from a source material containing a paraffin having 2 to 6 carbon atoms and an olefin having 2 to 6 carbon atoms includes a first step of bringing the source material into contact with a silver ion-containing solution (absorption liquid) at a predetermined temperature and pressure in an absorption column 1 and recovering a non-absorbed gas not absorbed by the absorption liquid while the olefin in the source material is preferentially absorbed by the absorption liquid, and a second step of desorbing and discharging a gas component from the absorption liquid having undergone the first step at a predetermined temperature and pressure in a desorption column 2. The first step and the second step are performed continuously in parallel while the absorption liquid is circulated between 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.
