| Abstract | A method for purifying reclaimed polyethylene, such as polyethylene reclaimed from post-consumer use or post industrial use, is disclosed. The method involves obtaining the reclaimed polyethylene and contacting it at an elevated temperature and pressure with a fluid solvent to produce an extracted reclaimed polyethylene. The extracted reclaimed polyethylene is dissolved in a solvent at an elevated tem perature and pressure to produce a polyethylene solution, which is purified at an elevated temperature and pressure by contacting the polyethylene Solution with Solid media to produce a purer polyethylene Solution. A purer polyethylene is then separated from the purer polyethylene solution. |
