Title: (EN) PARAFFIN PURIFICATION METHOD AND APPARATUS
Abstract:
(EN) ABSTRACT 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 5 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 10 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 15 step are performed continuously in parallel while the absorption liquid is circulated between the first step and the second step. 111111111111111111111 111111111111111111 *G00002*
