1. A method for separating solid carbon dioxide particles from a carrier liquid and producing a substantially pure liquid carbon dioxide stream from the separated solid dioxide particles, the method comprising the steps of:
a. introducing a slurry stream (150) comprising a carrier liquid and solid carbon dioxide particles into an inlet section (140) of a vertical column vessel (102) under pressure;
b. allowing the solid carbon dioxide particles to settle by gravity into the lower end of the vertical column vessel (102) which defines a heating section (142), while displacing the less dense carrier liquid up, towards the upper end of the vertical column vessel (102);
c. heating the heating section (142) of the vertical column vessel (102) to melt the solid carbon dioxide particles to form a product liquid stream (151) of substantially pure carbon dioxide;
d. driving a majority carrier liquid stream (154) out of the vertical column vessel (102) through a carrier liquid stream outlet extending through the top of the vertical column vessel (102); and
e. driving the product liquid stream (151) of substantially pure carbon dioxide out of the vertical column vessel (102) through a product outlet at the lower end of the vertical column vessel (102) that is separate and distinct from the carrier liquid outlet.
