原料气带氨冲击事故如何处理？
参考答案：
本装置采用烧氨工艺，原料气允许氨含量在5～8％（V），原料气中的氨主要来自Ⅱ汽提装置的含氨酸性气。如果Ⅱ汽提生产波动，可能引起装置酸性气氨含量波动，少量的氨含量增加，及时提高酸性气预热器温度设定，提高酸性气进反应炉温度，同时适当提高反应炉温度，如反应炉温度较低，反应炉补瓦斯提高温度；如氨含量波动较大，Ⅱ汽提装置作降量或停工处理，Ⅱ汽提含氨酸性气停进本装置。

| I've celebrated Christmas many times, but this is the first time with family and relatives. My cousins from my mum's side invited us for Christmas celebration at their house this year. I don't see them often, as generally we're not that close to them. A bit history of them here. They were the children of my second uncle. He had two wives. The cousins I met there were from both. Four daughters and a son from the first, and two sons from the second. The rest were not around. The house we went to is in Tropicana, which was extremely large. I enjoyed the celebration we had yesterday. It's the usual stuff I've seen on TV, and heard from friends who celebrate them. Caroling (圣颂歌), having dinner, social talks, introduction of who is whose children etc., and not to miss, the food, delicious. I like the turkey sandwich. As usual, I looked and walked around after dinner, and to my surprise, two of my nephews, aged 22 and 25, look really beautiful, just like movie stars. The nieces were not bad at all. Some are very pretty, and the rest are all above average. We left about 11:30 pm. I sure hope to meet them again in the near future. Hopeful]y when rny cousin that I meet quite regularly, had her open house, also in Tropicana. | ||||||||||||
