关键词傅立叶变换红外光谱法氧化亚氮杂质分析一氧化氮纯气是一种重要的工业气体, 可用于硝化生产和聚氯乙烯制备。

在电子工业中用于硅氧化膜形成氧化和气相沉积等, 以及用于航天和卫星的推进剂, 还可用于大气检测标准混合气体的制备、[1]大气环境检测和相关仪器的检定校准。

而不同的应用领域对一氧化氮纯度要求各不相同, 子工业和标准物质制备行业, 氧化氮气体, 、氧化亚氮、二氧化碳、氮气、。

虽然使用气相色谱法可以对其中某些杂质进行定量分析, 但是由于某些杂质具有很强的腐蚀性和反应活性, 对色谱分离系统的要求较高, 所以该方法有明显的局限性; 而且相对于不同的组分常常需要改变色谱条件, 甚至更换色谱柱, 操作繁琐。

有文献研究表明, 使用的校正标准与待测样品的介质不同也会导致分析上的很大误[2]差。

TABLE OF CONTENTS Introduction (4)Specifications (6)Installation (7)Operational Start-Up (9)Troubleshooting (11)Flow Monitor Information (12)Repair Kit Information (13)Statement of Warranty (15)INTRODUCTIONFluid entering the meter passes through the inlet flow straightener which reduces its turbulent flow pattern and improves the fluid’s velocity profile. Fluid then passes through the turbine blades causing it to rotate at a speed proportional to the fluid velocity. As each blade passes through the magnetic field, created at the base of the pickoff transducer, AC voltage (pulse) is generated in the pick-up coil (see Figure 1). These impulses produce an output frequency proportional to the volumetric flow through the meter. The output frequency is used to represent flow rate and/or totalization of fluid passing through the turbine flow meter.FIGURE 1Schematic illustration of electric signalgenerated by rotor movementTURBINE METERThe FTB-1400 Series Turbine Flow Meter is designed to withstand the rigorous demands of the most remote flow measurement applications. The FTB-1400 Series Flow Meter maintains measurement accuracy and mechanical integrity in the corrosive and abrasive fluids commonly found in oil field waterflood project pipelines, in-situ mining operations, offshore facilities and plant locations. Simple to install and service, it can operate in any orientation (horizontal to vertical) as long as the“flow direction” arrow is aligned in the same direction as the actual line flow. For optimum performance, the flow meter should be installed with a minimum of 10 diameters upstream pipe length and 5 diameters downstream pipe length.FIGURE 2Typical cross-section of FTB-1411 throughFTB-1441 turbine flow meterSPECIFICATIONSMATERIALS of CONSTRUCTION: Body : 316 Stainless SteelRotor : CD4MCU Stainless SteelRotor Support and Bearings : 316 Stainless SteelRotor Shaft : Tungsten CarbideOPERATING LIMITATIONS:Temperature: -150 °F to +350 °F (-101 °C to +177 °C) The metershould not be subjected to temperatures above +350° F(177° C), or below -150° F (-101° C) or the freezingpoint of the metered liquid. High temperatures willdamage the magnetic pick-up, while lower temperatureswill limit the rotation of the rotor.Pressure : Maximum pressure ratings as follows:5,000 psi ─ all NPT meters up to 2"2,000 psi ─ 3" male NPT1,500 psi ─ 4" male NPT1,000 psi ─ 6" male NPT800 psi ─ all grooved end metersNote: Consult factory for pressure ratings for flanged meters. Accuracy:± 1.0% of reading Repeatability: ± 0.1%Calibration: Water (NIST Traceable Calibration) Corrosion: All FTB-1400 series turbine meters are constructed ofstainless steel and tungsten carbide. The operator mustensure that the operating fluid is compatible with thesematerials. Incompatible fluids can cause deterioration ofinternal components and cause a reduction in meteraccuracy.Pulsation andVibration: Severe pulsation and mechanical vibration will affectaccuracy and shorten the life of the meterFiltration: If small particles are present in the fluid, it is recommendedthat a strainer be installed upstream of the meter (see Table 1 WARNING: Pressure in excess of allowable rating may cause the housing to burst and cause serious personal injury.FLOW MONITOR:For a complete flow monitor package, Omega offers the FTB-1400 Series Flow Monitors (see Appendix B on page 12 for flow monitor information). These digital signal processing displays utilize the low-level frequency input from the FTB-1400 Series Turbine Meters to calculate flow rate and total. When ordered with an Omega FTB-1400 Series Turbine Meter, the included factory calibration will provide dependable and accurate flow information.REPAIR KIT:The FTB-1400 Series Turbine Meter Repair Kit is designed for easy field service of a damaged flow meter, rather than replacing the entire flow meter (see Appendix B on page 12 for repair kit information).Repair parts are constructed of stainless steel alloy and tungsten carbide and are factory calibrated to ensure accuracy throughout the entire flow range. Each kit is complete and includes the calibrated K-factor which is used to recalibrate the flow monitor or other electronics to provide accurate output data.INSTALLATION INSTRUCTIONSPrior to installation, the flow meter should be checked internally for foreign material and to ensure the turbine rotor spins freely. Fluid lines should also be checked and cleared of all debris.The flow meter must be installed with the flow arrow, etched on the exterior of the meter body, pointing in the direction of fluid flow. Though the meter is designed to function in any position it is recommended, where possible, to install horizontally with the magnetic pick-up facing upward.The liquid being measured should be free of any large particles that may obstruct rotation of the rotor. If particles are present, a mesh strainer should be installed upstream before operation of the flow meter. (See Table 1 on page 8.)TABLE 1 Strainer Mesh Installation DetailsThe preferred plumbing setup is one containing a by-pass line (Figure 3 on page 10) that allows meter inspection and repair without interrupting flow. If a by-pass line is not utilized, it is important that all control valves be located downstream of the flow meter (Figure 4 on page 10).This is true with any restriction in the flow line that may cause the liquid to flash. If necessary, air eliminators should be installed to ensure that the meter is not incorrectly measuring entrained air or gas.PARTNUMBER STRAINER MESH CLEARANCE FILTER SIZE FTB-1411, FTB-142160 × 60 .0092 260 Micron FTB-1412, FTB-142260 × 60 .0092 260 Micron FTB-1413, FTB-142360 × 60 .0092 260 Micron FTB-142460 × 60 .0092 260 Micron FTB-1425 60 × 60 .0092 260 MicronFTB-1431 20 × 20 .0340 .86mm FTB-1441 20 × 20 .0340 .86mmCAUTION: Damage can be caused by striking an empty meter with a high velocity flow stream.It is recommended that a minimum length, equal to ten (10) pipe diameters of straight pipe, be installed on the upstream side and five (5) diameters on the downstream side of the flow meter. Otherwise, meter accuracy may be affected. Piping should be the same size as the meter bore or threaded port size.Do not locate the flow meter or connection cable close to electric motors, transformers, sparking devices, high voltage lines, or place connecting cable in conduit with wires furnishing power for such devices. These devices can induce false signals in the flow meter coil or cable, causing the meter to read inaccurately.If problems arise with the flow meter and monitor, consult Appendix A (Troubleshooting Guide) on page 11. If further problems arise, consult the factory.If the internal components of the turbine flow meter are damaged beyond repair, turbine meter repair kits are available. Information pertaining to the turbine meter repair kits is referenced in Appendix B on page 12.OPERATIONAL START-UPThe following steps should be followed when installing and starting the meter.WARNING: Make sure that fluid flow has been shut off and pressure in the line released before attempting to install the meter in an existing system.1. After meter installation, close the isolation valves and open theby-pass valve. Flow liquid through the by-pass valve for sufficient time to eliminate any air or gas in the flow line.CAUTION: High velocity air or gas may damage the internal components of the meter.2. Open upstream isolating valve slowly to eliminate hydraulic shockwhile charging the meter with the liquid. Open the valve to full3. Open downstream isolating valve to permit meter to operate.4. Close the by-pass valve to a full closed position.5. Adjust the downstream valve to provide the required flow ratethrough the meter. Note: The downstream valve may be used as a control valve.FIGURE 3Meter installation utilizing a by-pass line(Shown with an FTB-1400 Series Flow Monitor)FIGURE 4Meter installation without utilizing a by-pass lineAPPENDIX ATROUBLESHOOTING GUIDE Trouble Possible Cause RemedyMeter indicates higher than actual flow rate -Cavitation-Debris on rotor support-Build up of foreign materialon meter bore-Gas in liquid-Increase back pressure-Clean meter-Clean meter-Install gas eliminatorahead of meterMeter indicates lower than actual flow rate -Debris on rotor-Worn bearing-Viscosity higher than calibrated-Clean meter and add filter-Clean meter and add filter-Recalibrate monitorErratic system indication, meter alone works well (remote monitor application only) Ground loop in shielding Ground shield one placeonly.
