Multipoint flux monitoring by the hydrogen collection method using a new wide temperature range flux measurement probe

摘要

The hydrogen collection method is used widely to measure hydrogen flux in various oil processing environments. The inherent advantages are the method's non-intrusivity, ease of application, speed and dynamic range of measurement, and tolerance of variable steel temperature and curvature. In this paper we present preliminary measurements from a newly developed device based on the hydrogen collection method of flux measurement, which enables readings to be taken from up to four external probes sequentially, within a short time cycle. Prospective applications of the new tool will be discussed in the context of the results presented, such as for hydrogen bake out monitoring.
