09机组是合成装置中的关键设备,若出现意外停车,将使合成系统连续生产中断,造成极大的经济损失。要使09机组正常运行,必须保证润滑油质。另外,润滑油还起着密封压缩介质——氨气的作用。 由于润滑油不可避免地要与工艺介质接触,因此,经常出现油中进氨,使其质量指标(主要是破乳化度)超标,从1989年试运行至今,已先后换过七次油,仅油品价值一项就达12.6万元。因此,必须设法将09机组润滑油的质量指标控制在合格范围内。 经对每次换下的油品进行分析,润滑油的破乳化时间达到或接近80分钟,而其它各项质量指标均在正常范围内。因此,油品破乳化指标偏高是09机组频繁换油的主要原因。
09 unit is the key equipment in the synthesis device. If there is accidental stoppage, the continuous interruption of the synthesis system will be caused, resulting in great economic loss. 09 unit to make the normal operation, we must ensure that lubricating oil quality. In addition, the lubricating oil also plays a role of sealing the compressed medium - ammonia. As the lubricant inevitably come into contact with the process medium, ammonia is often introduced into the oil so that the quality index (mainly the degree of demulsification) exceeds the standard. Since the pilot operation in 1989, the oil has been changed seven times and has been changed only seven times A value of oil reached 126,000 yuan. Therefore, we must try to 09 units of lubricating oil quality control in the qualified range. After each replacement of the oil for analysis, the demulsification of lubricating oil time to reach or close to 80 minutes, while the other quality indicators are in the normal range. Therefore, the high oil demulsification index 09 unit is the main reason for frequent oil changes.
