Abstract
A gravitational separator for separating solids from liquefied natural gas having a closed tank having a conical lower portion angled at least 60.degree. from the horizontal and terminating at the bottom in an apex opening in communication with a valve means for removing settled solids from the tank, a vertically positioned cylindrical shell, defining a stilling chamber, located at least partially below a predetermined level of liquified gas, a conical shell vapor disengaging means located above the stilling chamber, conduit means for feeding a gas or liquefied gas containing impurities terminating in the stilling chamber below the level of a liquefied gas in the tank, means for withdrawing a gas or vapor from the tank. A process of separating impurities from a stream of methane by feeding the stream to a tank through a conduit terminating inside of a stilling chamber beneath the level of liquefied methane, said stilling chamber being defined by a cylindrical shell located in the tank at a position to depend at least partially below a level of liquefied methane in the tank and extending to below the terminus of the feed conduit, said tank being closed and having a conical lower portion angled at least 60.degree. from the horizontal and terminating at the bottom in an apex opening in communication with a valve, settling out solidified impurities in the lower portion as a slurry with liquefied methane, removing the slurry, and withdrawing methane vapor from the upper space of the tank.
