Patent GB-657748-A (GB)
Title: Improvements in or relating to methods and apparatus for separating gaseous mixtures into their components
IPC: F25J3/04
Filed: 1947-04-01
Abstract: 657,748. Separating gases. KELLOGG CO., M. W. April 1, 1947, No. 8786. Convention date, May 1, 1944. [Class 8(ii)] In a process for cooling a compressed gas mixture, e.g. air containing a condensible constituent, e.g. carbon dioxide in a heat exchanger 39, Fig. 1, by counterflowing gas, e.g. nitrogen from a rectifying column 50 not greater in mass quantity than the mixture, and deriming the exchanger 39 by a reverse flow of a gaseous stream free of condensibles and containing at least a portion of the counterflowing nitrogen, the difference between the temperature at which condensation occurs and the temperature of the counterflowing gas is maintained less than it would otherwise be by passing through an adjacent separate auxiliary path 74 a counterflowing stream, e.g. returning nitrogen or air leaving the exchanger 39 thereby providing a mass of counternowing gas greater than that of the mixture being cooled. In operation and with a four way valve 28 in the position shown compressed air to be separated in the column 50 is cooled to -253‹F in paths 32, 33, 34, 35 of exchangers 36, 37, 38, 39 in countercurrent heat exchanger with returning oxygen gas at -288‹F in paths 62, 63, 64, 65 and with returning nitrogen at -282‹F in paths 80, 81, 82, 83. Condensed water and carbon dioxide ice is sublimed from the paths 35, 34, 33, 32 by adjusting valves 78, 41 and the valve 28 to which they are coupled so as to direct the nitrogen along the paths 35, 34, 33, 32 to a discharge duct 84 and the air to be cooled along the paths 83, 82, 81, 80 to the valve 41. The temperature of the nitrogen returning from the column 50 along a duct 71 to the valve 78 is increased from -275‹F to the working temperature of -262‹F at which carbon dioxide is effectively sublimed by allowing a portion of the nitrogen stream to traverse the duct 74 where it absorbs heat from the exchanger 39 before passing along a duct 75 to rejoin the main stream at the valve 78. The cooled air after leaving the valve 41 and a surge drum 43 is divided into two portions, the larger of which is liquified by returning nitrogen at a liquefier 46 and enters a reboiler 48 at -274‹F from which liquid air is led through a duct 51 and a carbon dioxide filter 52 to the top of the column 50, and the remainder of the cooled air is expanded at an expander 55 to 25 lbs. per square inch pressure at -304‹F and is then fed at a duct 56 into the coloumn 50. Air is byepassed at a duct 85 for starting purposes. In a modification the duct 74a, Fig. 2, is traversed by a portion of the cooled condensible-free air leaving the duct 35a and which rejoins the main stream at a duct 42a prior to its entry into the surge drum.
