Abstract

1,045,707. Electrostatic separation. CONCH INTERNATIONAL METHANE Ltd. Sept. 27, 1965 [Oct. 15, 1964], No. 41026/65. Addition to 1, 017. 660 Heading B2J. The process described with reference to Fig. 1 of the parent Specification is modified in that, prior to reducing the pressure of the mixture of liquified gases, the mixture is subjected to an ionization step in order to produce an increased concentration of charged solid particles during the pressure reducing step. The process may be applied to the separation of mixtures including two or more different gases, e.g. the separation of CO 2 and/or H 2 S from natural methane gas, CO 2 from air or CO 2 from a nitrogen/CO 2 mixture. One form of apparatus for separating CO 2 from methane gas, Figs. 1 and 2 (not shown) is as described in Figs. 1, 3 and 4 of the parent Specification except that a section of the pipeline leading from the liquefaction plant to the throttling valve is protected by lead shielding and contains a source of gamma radiation, e.g. a radioactive material such as Cobalt 60, for ionizing the mixture of liquefied gases before throttling. Ionization may alternatively be effected by means of a charging electrode 30 leaving sharp points 31, Fig. 3, located in a conductive pipe 3<SP>1</SP> before the throttling valve 8<SP>1</SP>.
