1,3-丁二烯测毒管 1,3-Butadiene CH2=CHCH=CH2 2.5-100ppm

简要描述:

168SC 1,3-BUTADIENE 1,3-丁二烯测毒管 1,3-Butadiene CH2=CHCH=CH2 2.5-100ppm,在乙烯裂解气、加氢裂解汽油气摆塔里硫化氢的监控也使用硫化氢检测管法。硫化氢检测管还常常用于加氢裂化、液化气回收、加氢精制、铂重整等装置中高分气、低分气、循环气、产品分离气、塔顶气以及补充氢中硫化氢的中间控制。在加氢裂化催化剂还原、活化过程中的硫化氢监控分析,使用检测管法更显示它的优越性。因为在催化剂还原过程中半小时一次的控制分析是其它分析方法所不能胜任的。
