SRU enrichment

Solutions for oxygen enrichment on SRUs (Sulphur Recovery Units).

Sulphur recovery and acid gas plants

Oxygen used in SRU can increase the plant capacity and helps with contaminants and low hydrogen flows, or it can also be applied to boost heating. We can provide oxygen in two ways -intermittent or continuous.
