介绍了合成氨厂在液氮洗精制气未合格之前的状况，采取了提前用氮气开启氢氮气压缩机打内循环、待液氮洗精制气合格后完成无间隔接气的措施，结果表明：缩短了约2h的开车时间，减少了约16万m3的精制气放空，大大降低了开车成本。
介紹瞭閤成氨廠在液氮洗精製氣未閤格之前的狀況，採取瞭提前用氮氣開啟氫氮氣壓縮機打內循環、待液氮洗精製氣閤格後完成無間隔接氣的措施，結果錶明：縮短瞭約2h的開車時間，減少瞭約16萬m3的精製氣放空，大大降低瞭開車成本。

This paper introduces the condition of ammonia unit before purified gas from liquid nitrogen wash section is offspec. After taking the meas-ure of adopting nitrogen to startup H2/N2 compressor for internal circulation in advance and realizing interval-free switch over after the purified gas from liquid nitrogen wash section reach the standard, the results show that the startup time is shortened by about 2 hours and 160 000 m3 purified gas vented to the air is reduced, which greatly cuts down the startup cost.
