摘要： In a method for separating argon by cryogenic distillation, in which a flow containing argon, oxygen and nitrogen and being more rich in argon than the air is sent to a distillation column, and an argon-rich gas flow is withdrawn at the top of the column, a portion of the argon-rich gas flow is mixed with beads to form a gas mixture containing beads, the beads being capable of adsorbing oxygen in the presence of argon at the column operating temperatures; the portion of the argon-rich gas flow mixed with the beads is condensed and then sent to the top of the column; and a bottom liquid containing beads is withdrawn from the column and treated to remove the beads, the beads removed being regenerated to remove the adsorbed oxygen and being again mixed with the argon-rich gas flow.

摘要： Disclosed herein are new processes for adsorbing oxygen using adsorbent compositions comprising RHO zeolites kinetically selective for oxygen. The RHO zeolites can be used in pressure swing adsorption processes for separating oxygen from oxygen containing streams, such as for, but not limited to, purifying a crude argon feed stream or separating oxygen from an air feed stream.

摘要： The present invention generally relates to a method to enhance heat transfer in the temperature swing adsorption process (TSA) and to an intensified TSA process for gas/liquid purification or bulk separation. Helium is designed as the heat carrier media to directly bring heat/cool to the adsorbent bed during the TSA cycling process. With helium's superior heat conductivity, the time consuming regeneration steps (warming, regeneration and precooling) of TSA process can be significantly reduced and allowing for the TSA process to be intensified.

摘要： An optimal material composition that allows for the purification of at least one feed component from a fluid feed stream such that the adsorbent has an oxygen capacity of at least 10 weight percent is described. More specifically, the material is an adsorbent for purification of a fluid feed stream having an oxygen to argon selectivity greater than or equal to a ratio of 3:1 and an oxygen capacity of greater than or equal to 10 weight percent, wherein the oxygen capacity is measured at a pressure in the range of about 9-10 Torr and a temperature of 77 degrees Kelvin after 4 hours of equilibration time and wherein the oxygen to argon selectivity is obtained by dividing the oxygen capacity by the argon capacity of the adsorbent measured at a pressure in the range of about 697-700 Torr and a temperature of 87 degrees Kelvin after 8 hours of equilibration time. The adsorption capacities are measured on a pure component basis.

摘要： This invention is directed to a method for recovering, purifying and recycling an inert gas on a continual basis in connection with a silicon crystal pulling process. Silicon oxide impurities generated during the crystal growth process are completely oxidized by in-situ oxidation with a regulated amount of an oxidizing source gas mixture to form silicon dioxide impurities, which can be removed by a particulate removal device. The particulate-free effluent enters a purification unit to remove the remaining impurities. The inert gas emerging from the purification unit can be fed back into the crystal puller apparatus and/or mixed with the oxidizing source gas mixture. As a result, the ability to increase silicon crystal throughput, quality and at the same time reduce the costs associated with recycling the inert gas can be achieved.
