METHOD OF USING HIGH PRESSURE LN2 FOR COOLING REACTORS

摘要

An apparatus for and method of delivering a liquid cryogen into a reaction vessel to cool an exothermic reaction within the vessel wherein the liquid cryogen can be supplied directly into the reaction vessel at a maximum high pressure of about 3000 psi is provided. The liquid cryogen may come directly from a high pressure liquid cryogen storage tank without any pressure regulators or control valve between the reaction vessel and the storage tank thereby reducing flashing and eliminating the need for sub-cooling the liquid cryogen.
