Process for the purification of a cryogenic fluid by filtration and/or adsorption

摘要

Process and apparatus for the purification of a cryogenic fluid in liquid, diphase, gaseous or supercritical state, having a boiling point Pe, with at least one of its impurities having a boiling point Pe', with Pe'>Pe. The process includes at least one step selected from the group comprised by: a filtration step of at least one impurity in solid state, and an adsorption step of at least one impurity in liquid or gaseous state; and in which there is recovered at least one portion of the cryogenic fluid at least partially purified.
