在合成氨的生产过程中,从造气到氨的合成,生产介质都是气体,流量大,压力高。生产过程中使用催化剂多,因此开停工的时间长,放空声音大,尤其在更换催化剂时,六种催化剂升温还原,有时竟达到二十几天时间。开停工时因气体放空声音大,尤其是压控—11处氮氢气的放空,严重地影响了周围的环境,使合成车间附近的车间、分厂及总厂厂部都不得安宁,刺耳的声音使人心情烦燥疲劳乏困,甚至关窗闭门谈话和打电话仍感到困难,会议也收不到好的效果,严重地影响了工作,
In the synthesis of ammonia production process, from gas to ammonia synthesis, the production of media are gas, large flow, high pressure. Due to the use of more catalysts in the production process, it takes a long time to shut down and emit loud sounds. In particular, when the catalyst is replaced, the temperature of the six catalysts is reduced and sometimes reaches twenty days. Opening and closing work due to the sound of the gas venting, especially the pressure-controlled nitrogen and nitrogen at the 11 of the vent, has seriously affected the surrounding environment, so that the workshop near the synthetic plant, plant and plant plant are not allowed peace, harsh sound Make people feel tired and sleepy mood, and even close the window to close the door and still feel difficult to call, the meeting also received no good results, seriously affecting the work,
