The package consists of one compressor, a cooler, a scrubber and two towers with Sulago® beads.
To operate successfully the following precautions are necessary.
Design criteria:
- Diameter (low contact speed causes insufficient absorption).
- Height (crushing pressure)
- Two vessels (heat transfer)
- Stainless steel (hot H2S + H2O is aggressive)
- Drain water is acid, toxic and explosive in contact with water (dangerous: add water not inverse).
This system is suitable for small capacities (<1000 Nm3/h) and low H2S values (<250 ppmv H2S).
