微库仑在线测硫仪的研制

Design of an on-line total sulfur analyzer based on micro-coulometry

介绍了一种用微库仑法测定气体中总流的在线分析仪，用于合成氨脱硫净化气或其它有机气体中总硫的连续自动测定。仪器测定范围为0．01～1000mg3，精密度为2％，响应时间为2min（90％响应值），已在合成氨生产线连续运行了3年。

An on-line total sulfur analyzer based on micro-coulometry was designed for continuous determination of total sulfur in desulfurized gas of sguthetic ammonia or other organic gases. The measurement range is 0. 01 ~ 1000mg/m3, the relative standard deviation is ≤2 .0 % and the response time is 2 min (90 % response value). The analyzer has been used on the preduction line of synthetic ammonia for three years successfally.
