ABSTRACT:
A method and apparatus for recycling the bottoms product from an absorber tower back to the absorber tower. However, before the bottoms product is returned to the tower, the solid particles entrained therein are removed via one or more centrifuges closely coupled to the absorber tower. These centrifuges are located adjacent the tower and are elevated with respect to the tower such that their centrate can be directly returned or delivered back to the absorber tower via gravity.
