What is used to measure hydrogen and hydrocarbons in oil refining reforming?
Thread Content
In refinery catalytic reforming, the hydrogen and hydrocarbon content in the regeneration gas (nitrogen) is measured; the design institute specified the use of a thermal conductivity analyzer, but I think a FID would be better for this purpose. What type of analyzer are you using in this application? Share your opinions and let’s discuss!
Please correct the spelling mistakes first before we discuss it. It’s called “light hydrocarbons,” not “hydrogen hydrocarbons,” because there is nothing such as hydrogen hydrocarbons.
Reply 2# qugd is a hydrocarbon; the sample gas is mainly nitrogen, with hydrogen and hydrocarbon substances present
The thermal conductivity type works perfectly; I use a Rosemount Cat200 here, and it performs well. Using chromatography, however, requires too much maintenance
There is no need to use chromatography; as long as the stability shows good repeatability, highly precise measurements are not required. When UOP filed the patent, it designated only 2 companies; currently, in China, ROSEMOUNT is the preferred choice, as a fixed pattern has emerged for processes including pretreatment. Moreover, the technology for 15% HC-1% H2 is already in ROSEMOUNT’s possession, and the conversion formulas have not been made public.
