Hydrogen Applications in Refineries |
| Hydrogen demand will increase in the upcoming years as a result of stricter environmental legislation, more extensive processing of residues and higher diesel demand compared with gasoline.
There are various hydrotreating processes in a refinery. To name only a few of them:
- Hydrodesulfurization: sulfur compounds are hydrogenated to hydrogen sulfide H2S as feed for Claus plants
- Hydroisomerization: normal paraffins are converted into iso-paraffins to improve the product properties (e.g. RON)
- Dearomatization: aromatics are hydrogenated to cyclopa-raffins or alkanes
- Hydrocracking: long-chain hydrocarbons are cracked to shorter chains in the gasoline range
The picture below shows the basic flow diagram of a refinery:

Hydrogen volumes consumed increasingly exceed those produced in a platformer and have to be supplemented by other sources.
Main processes for hydrogen on-site supply:
- Steam reforming of methane or other hydrocarbons
- Recovery from refinery off-gases
- Recovery from syngas
- Gasification of oil refining residues
Our service options for hydrogen applications:
- Process consulting
- Plant financing, erection and start-up
- Hydrogen plant operation (over-the-fence-supply), maintenance and repair
- Emergency supply arrangements
