Gas Plant with Capacity 60000 Nm3/hour Hydrogen and 14500 Nm3/hour Carbon Monoxide

AIR LIQUIDE HyCO

Used hydrogen plant designed to produce high purity hydrogen and carbon monoxide from natural gas. Built by Air Liquide and first operated in 2015, shut down in August 2024.

Output capacity as follows:
- Hydrogen 60000 Nm3/hour with 99.99% purity.
- Carbon monoxide 14500 Nm3/hour with approximately 99% purity. (Actual purity depends on volume of nitrogen in the natural gas feedstock.)
- Superheated 40 bar steam by-product.

The HyCO plant includes the following (5) main sections:
- Syngas generation / steam reforming and steam generation
- Gas cooling
- CO2 scrubbing
