如何選擇合成塔工藝氣91福利片导航网

傳統的氨合成塔氣分析由於NH3和CO2的存在,使分析方法變的困難和複雜,國內大型合成氨廠都需要2-3台色譜儀多次進樣才能得到分析結果,而且還需要3+1的硫酸溶液來吸收氨才能得到H2、O2、N2、CO、CH4的含量,如此分析更是難以定量,隻能再通過複雜的計算才能得到分析所需要的濃度。

而我公司的合成塔工藝氣91福利片导航网GC-7860-DW有效地解決了合成塔工藝氣分析中長期困饒的問題,該儀器采用進口閥件及管路,配置操作簡單、維護方便且分析效率高;所有組分均出在一張譜圖上方便使用校正歸一法計算,能夠得到準確的全組分含量 ;檢測範圍為0.01%-100%(體積分數)。

合成塔工藝氣91福利片导航网GC-7860-DW適用範圍: 氨合成塔工藝氣    尿素合成塔工藝氣    合成塔循環氣、入塔氣、出塔氣、馳放氣、放空氣、再生氣等

合成塔工藝氣91福利片导航网GC-7860-DW分析過程:用工藝氣樣品衝洗取樣係統的定量管,跟大氣平衡後,轉動十通進樣閥;樣品由進樣十通閥導入分析係統,先經過柱1,在柱1 NH3得到分離,其餘的組分流出進入柱2,NH3保留在柱1中,切換十通閥反吹柱1,NH3流出在TCD檢測器響應;在柱2 中CO2同時也得到了保留,H2、O2(Ar)、N2、CO、CH4等氣體進入柱3,在H2還沒流出柱3時轉動六通閥使CO2流出柱2進入TCD檢測器,zui後在放出柱3中的氣體,分析過程結束。
