Sublimation systems and associated methods

摘要

A system for vaporizing and sublimating a slurry comprising a fluid including solid particles therein. The system includes a first heat exchanger configured to receive the fluid including solid particles and vaporize the fluid and a second heat exchanger configured to receive the vaporized fluid and solid particles and sublimate the solid particles. A method for vaporizing and sublimating a fluid including solid particles therein is also disclosed. The method includes feeding the fluid including solid particles to a first heat exchanger, vaporizing the fluid, feeding the vaporized fluid and solid particles to a second heat exchanger and sublimating the solid particles. In some embodiments the fluid including solid particles is liquid natural gas or methane including solid carbon dioxide particles.

1. A method, comprising:
feeding a slurry comprising solid particles suspended in a first fluid to a first heat exchanger; feeding a second fluid comprising gas having a higher temperature than the slurry into the first heat exchanger to mix with the first fluid and to vaporize the first fluid in the first heat exchanger to form a first gas; feeding the first gas and the solid particles to a second heat exchanger; and feeding at least a portion of the second fluid comprising gas having a higher temperature than the slurry into the second heat exchanger to mix with the first gas and the solid particles and to sublimate the solid particles in the second heat exchanger to form a second gas.
