Heat protective atmosphere of nitrogen engineering design station

Operating procedures. * 32 * 1998 cryogenic technology 4.4-4. 3 fixture to prevent the wrong equipment for filling joints, to prevent the gases mixed. 4 -. 4.4 pairs of factory to provide the pressure 14.7MPa pressure ~ z5x3.5mm strength check calculation of copper were found inadequate safety margin, we changed to $ 28x5mm brass tube, which increases strength, to ensure security. 4.5 Construction of the laboratory to improve the operation of air separation equipment, the quality of our press equipment safety, the requirements of economic operation of the laboratory building. We will run an air separation plant gas samples of the control points, through the sampling tube connected to the laboratory control valve, pressure regulator valve connected filters and analytical instruments, major projects are: 4.5.1 After the high-pressure air purification system Determination of dew point and co2, the use of the instrument is produced by Shanghai Instrument Factory of Tangshan DWS. Ⅱ B-type analyzer and trace water in Nanjing Analytical Instrument Factory production of DD. t0-type micro co2 analyzer. Thus, we can understand the work of purification devices, molecular sieve effect of how it sets the switching period fitness, etc., can effectively avoid the water, co2 into the fractionation tower block caused by freezing, which is a stable production yield and reducing consumption are good guide. 4.5.2 ammonia, oxygen purity monitoring, the use of third Nanjing Analytical Instrument Factory production ZO. t02A Pei oxide oxygen analyzer. 4.5.3 liquid oxygen, liquid air, oil and hydrocarbon matter content of Taiwan, Shanghai Third Analytical Instrument Factory with the production of 722 grating spectrophotometer.
