Detailed Description

The essence of the present invention is the new characteristics of the quartz glass discovered by the inventors. It comprises a mass selective fluid band-pass filter (8). The mass selective fluid band pass filter is a subcooled liquid. The supercooled liquid is quartz glass (9). The quartz glass, wherein the quartz glass is composed of quartz of natural or artificial origin. The mass selective fluid band pass filter wherein the apparatus provides high selectivity in gas separation. The mass selective fluid band pass filter provides a method of very selectively filtering gases having close atomic mass unit values over the operating range of such filters. The mass selective fluid bandpass filter, wherein the particular atomic mass unit at which maximum transport occurs is affected by factors including: temperature of the glass, pressure differential across the glass, and composition of the glass. The mass selective fluid band made of quartz glass provides a method wherein the atomic mass unit of maximum transport is directly related to the temperature at which the mass selective fluid band made of quartz glass passes through the filter. The particular atomic mass unit at which maximum transport occurs is affected by factors including: a temperature of the mass selective fluid bandpass filter made of quartz glass, a thickness of the mass selective fluid bandpass filter made of quartz glass, a pressure differential in the mass selective fluid bandpass filter made of quartz glass, and a composition of the mass selective fluid bandpass filter made of quartz glass. The mass selective fluid band made of quartz glass provides a method in which species of a given atomic mass unit (species) are selectively transported while species of higher and lower atomic mass unit values are selectively blocked under set conditions, wherein the mass selective fluid band exhibits high quality or "Q" characteristics through a filter. The mass selective fluid band pass filter made of quartz glass provides a method by which the mass selective fluid band pass filter can selectively pass gas species of a predetermined atomic mass unit value under isothermal operation. The mass selective fluid band pass filter made of quartz glass provides a method of very selectively filtering gases having close atomic mass unit values over the operating range of such filters.

Said mass selective fluid band pass filter made of quartz glass provides a means of being selectively semi-permeable to the gas to be filtered by the apparatus. The effect of selective semi-permeability to the gas to be filtered is based on the conditions of glass thickness, glass temperature, glass composition and pressure differential across the glass.

The mass selective filter provides a means of separating a predetermined gas from a gas mixture or the atmosphere. The gas selection method consists of: a gas inlet structure (6), a gas inlet space (7), a mass selective fluid band pass filter, a gas outlet space (10) and a filtered gas outlet (11). The gas selection method provides two internal bounded spaces separated by a structure of titanium, stainless steel, borosilicate glass, sealing glass, quartz glass, and other metal alloys. The mass selective fluid band pass filter consists of a sintered metal tube (14) to which quartz glass has been sealed by the person skilled in the art (14). The quartz glass has a temperature sensor (16) on its surface and a temperature changing device (19) spirally wound on its surface. The sintered metal is comprised of a metal selected from the group consisting of: 1) titanium, 2) stainless steel, 3) aluminum, 4) alloys of these metals, or 5) another metal and/or alloy determined to be most suitable for a given condition. In an alternative embodiment, the mass selective fluid band pass filter consists of a quartz glass capped tube that is mated to a hybrid adapter tube (reflector) by a multi-layer sealing glass (not shown). The temperature sensor is on the glass surface and the temperature changing device is spirally wound on the glass surface. The structure of stainless steel, borosilicate glass and sealing glass is impermeable to the gases to be filtered through the apparatus. The quartz glass is selectively semi-permeable to the gas to be selected by the apparatus. The selective semi-permeability of the gas to be filtered by the device described is based on the conditions of glass thickness, glass temperature, glass composition and pressure differential across the glass. The selected method employs one or more effects selected from the group consisting of: 1) a gas inlet, 2) a gas inlet space, 3) a mass selective fluid band pass filter, 4) a gas outlet space, 5) a filtered gas outlet, and 6) an unfiltered gas outlet structure (12). The gas inlet, gas inlet space, mass selective fluid band pass filter, gas outlet space and unfiltered gas outlet arrangement mounted in the housing (21) and one or more end caps (20) combine together to form a mass selective fluid band pass filter (23) mounted in the housing. These units may be combined sequentially and in series. The temperature varying device is comprised of a device selected from the group consisting of: a) a metal resistance band; b) a flat tube for transporting a fluid at a predetermined temperature.

The mass selective fluid band pass filter is a high "Q" fluid band pass filter, one example of which is shown in fig. 1 and described above, which forms a means of separating a predetermined gas from a gas mixture or atmosphere. A mass selective fluid bandpass filter is disclosed. The filter is used to select gas molecules of a particular mass from a gas sample containing molecules of two or more mass species. The filter provides an operating means for selecting a predetermined gas from a group of gases or atmosphere. The filter is a supercooled liquid composed of quartz glass. The quartz glass of the mass selective fluid band pass filter is composed of quartz of natural or artificial origin.

These components and structures are assembled in accordance with current practice by those skilled in the art. The assembly provides two vacuum and pressure tight external connections to connect to the internally contained gas inlet structure and gas outlet structure. The space defined by the assembly provides two internally defined spaces separated by the structure of the mass selective fluid band through the filter. The quartz glass is selectively semi-permeable to the gas to be filtered by the apparatus. The selective semi-permeability of the gas to be filtered is based on the conditions of glass thickness, glass temperature, glass composition and pressure differential across the glass.

Gases containing species having different atomic and molecular masses are introduced into the gas inlet space through the gas inlet. A predetermined gas mass species from the gas mixture is selectively transmitted through the semi-permeable quartz glass portion of the mass selective fluid band pass filter. The filtered gas is collected in the gas outlet space and discharged through the filtered gas outlet. The outlet gas may be used directly or repeatedly passed through a mass selective fluid filter(s) mounted in the housing(s) to bring the purity of the gas to the level required by the application, as the "Q" value and selectivity may vary for different predetermined gas species.

The semi-permeable quartz glass mass selective fluid band pass filter behaves like an electrical series resonant circuit consisting of a resistor, a capacitor and an inductor. Gas transmission is highest under equivalent conditions of series resonance, where capacitive and inductive reactances cancel out and circuit transmission is limited by the Direct Current (DC) resistance of the circuit. In this case, resonance represents a molecular or atomic mass species in the AMU.

The particular AMU at which the maximum transmission occurs is affected by factors including: temperature of the glass, pressure differential across the glass, and composition of the glass. It has been observed that the maximum transmitted AMU is directly related to the temperature of the glass. A positive correlation between AMU and glass temperature has been observed over the range of temperatures observed during the experiment. Higher values of AMU are typically selectively passed as the temperature increases.

The filter is a mass selective fluid bandpass filter in which species of a given AMU are selectively transported, while species of higher and lower AMU values are selectively blocked, under set conditions. The filter exhibits high quality or Q characteristics. Q is defined as the rejection characteristics of a species slightly above or below the AMU value, relative transmission at a given AMU value.

The selectively passed AMU value for a given set of operating characteristics of the glass composition and pressure differential is controlled by the temperature of the glass. By adjusting the activity of the temperature-varying device wrapped on the glass, and by adjusting the temperature and rate of fluid flow through the heat exchanger fluid line (5) and within the heat exchanger (4), the auxiliary electronics (29) determines the glass temperature and maintains it within a predetermined temperature range. The temperature is monitored and controlled by temperature sensors, electronics, cable(s) (28), heat exchangers and temperature changing devices. A mass spectrometer (17) monitors the mass of the gas.

By operating at a constant temperature, the mass selective fluid bandpass filter is capable of selectively passing gas species of a predetermined AMU. The observed selectivity profile indicates that species within 1AMU of its range can be selectively transported or excluded. The temperature of the glass can be adjusted to change the given substance that permeates at a given time.

The pressure differential in the mass selective fluid bandpass filter is at 1E^-8To within a total pressure window of 10,000 PSI. The pressure differential is set for a particular selected gas and operating conditions.

The gas temperature in the gas inlet space and the temperature of the mass selective fluid band-pass filter are maintained at predetermined temperatures. Maintaining the temperature by one or more devices selected from the group consisting of: 1) means for regulating the temperature and rate of fluid flow through the fluid lines of the heat exchanger and within the heat exchanger, 2) temperature varying means wound directly on the glass surface of the mass selective filter, 3) temperature sensors at predetermined locations, 4) electronics, 5) insulation means (not shown) of given parameters adapted to the particular application. The temperature of the mass selective fluid band passing through the filter is maintained within a total temperature window of-200 to +1000 ℃. The temperature is set for the particular selected gas and operating conditions.

In the case of artificial quartz, the invention comprises adding a predetermined chemical modifier in a predetermined amount during the manufacture of the artificial quartz glass. The chemical modifier is one or more elements in the element group with the atomic numbers of 1, 3-9, 11-17, 19-35, 37-53, 55-85 and 87-109; wherein the form of the element is selected from: metals, gases, molecules, salts, rare earths, oxides, chlorides, ions, carbonates, acids, bases or other forms suitable for the conditions of glass manufacture.

(a) the quartz glass film was thinned starting from our initial experimental conditions.

(b) Pressure is applied to the gas in contact with the glass.

(c) Increasing the pressure differential across the glass.

(d) A plurality of tubes are used in the filter structure.

(e) The thin quartz glass layer is supported by a sintered quartz glass support.

(f) The thin quartz glass layer is supported by a sintered metal support.

(g) And heating at high temperature to fuse the glass to cover the supporting sintered material.

(h) The thickness of the quartz glass film is increased to raise "Q".

In the above description, we propose what we consider to be the correct theory of operation. Although we believe these theories are correct, we do not wish to be bound by them. While the principles of the invention have been described above in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation on the scope of the invention. Accordingly, the scope of the present invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
