There are problems in the process flow 2 of the -1 air pressure source purification system. 1. The pneumatic large valve of the 500,000 cryogenic separation device is not flexible. In the gas pipeline inspection and removal in March this year, it was found that the water in the pneumatic valve chamber was the root cause of its inflexibility.
Breakpoints caused by corrosion of humid air and sulfur-containing natural gas result in More alarm stops.
3. In winter, due to the low outdoor ambient temperature, the moisture in the compressed air in the pipe is frozen and blocked, resulting in a poor air path, resulting in inaccurate operation of the pneumatic instrument and pneumatic regulating valve at the whole station.
1 Dryer regeneration effect analysis For the adsorption dryer, the regeneration of the adsorbent is an extremely important part. During the regeneration half-cycle, the adsorbed water must be completely desorbed and driven out of the tower. This consumes enough regenerative energy (including regeneration gas consumption and regeneration temperature), and the regeneration energy consumption is insufficient, which easily causes the adsorbent to “regenerate incompletely.†"The amount of residual water is left in the adsorbent bed." The presence of "residual water" equals an added value for the amount of adsorption, especially at the end of the adsorbent bed, which is the worst operating state in either the adsorption phase or the desorption phase. The accumulation of “residual water†increases at the end of the adsorbent bed, eventually causing the adsorbent in this region to lose its adsorption before other parts, which is equivalent to shortening the height of the adsorbent bed and reducing the contact time of the wet air with the adsorbent, resulting in drying. The outlet air dew point rises. Non-heat regenerative drying device dryer The drying air used for backflushing of silica gel is taken from the outlet of the dryer. It has a large moisture content and is not heated. It is used to improve the drying method of compressed air in the silica gel which has been saturated. Zhang Renmin Li Lianbao Shengli Oilfield Branch Oil and Gas Gathering and Transportation Plant Gudao Compressor Station Shandong Dongying 257231 can not meet the standard requirements in some problem dew points. Therefore, we propose to improve the drying equipment, improve the quality of compressed air, and ensure the smooth production.
Excessively from the negative bad quality of the damage to the high suction, the device must be used to separate the dry before the production of water efficiency of the thousands of valves, some of the low valve filter is enough to reduce the amount of dry and can be large, the agent should be Force attached. A good gas can absorb the evolution of the air. In the net fruit shrinking dust, the powder from the aging pressure is used as the gas separation agent and the empty line is added to the oil to be indented, and the suction and anti-repressor core machine is pre-closed and the filter is held. The air-protected load has a split-effect fruit filter. HyIs-x/XI force-absorbing and dry-drying fruit-absorbing device can contain thousands of water filters. Dust and dry!
