Abstract
A process and apparatus for liquefying natural gas includes a heavies recovery system. In another aspect, a liquefied natural gas (LNG) facility may employ an ethylene independent heavies recovery system. The recovery system may thus operate relying only on fluid input from upstream of an ethylene refrigeration cycle. A heavies-depleted stream recovered from a liquid withdrawn from a heavies removal column in the heavies recovery system may combine at a location downstream of the heavies removal column with an overhead withdrawn from the heavies removal column for further cooling of such combined stream into liquefied natural gas product.
