METHOD AND APPARATUS FOR PURIFYING PARAFFIN |
摘要 |
<p>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.</p> |
