Is venting the formed H2 gas through chemical hood ok or should a dedicated venting line be fabricated? The project in question involves methanol reforming at lab scale using a small reformer. Reactors and compression fittings are ¼-inch OD SS 316 lines.

Even if a small experiment is being run inside a fume hood, the best practice is to use a dedicated vent line for hydrogen which vents hydrogen to a safe location outside.  This is especially recommended for planned venting.   This practice avoids situations where flammable mixtures could develop. Each system is unique and should be evaluated and approved for  use independently…

Is it safe to use an inert gas nitrogen compressor for hydrogen service?

Such a compressor should NOT be used for hydrogen. There are many issues with converting a compressor to hydrogen service. First and most important, this must be approved by the manufacturer. Examples of concerns for a non-hydrogen compressor used for hydrogen service include (but are not limited to): 

  1. Are the materials compatible with hydrogen permeation, embrittlement,…
