Advantages of Sulaway plant Flow scheme
Upgrading of bio gas
An active carbon plant is a cheap investment, but extremely expensive in production and maintenance.
SULAWAY versus active coal
Active carbon can only be applied for H2S content smaller than 100 ppmV.
Extra investment costs due to process equipment:
- Blower/booster compressor
- One (1) heat exchangers
- Active coal
- Extra electric power
- Transport and processing of polluted waste, mainly carbon.
- Sulaway decreases costs by transforming H2S in sulfuric acid ( H2SO).
- Regular replacement of coal
- Sulaway plant checkup each half year for gas compressor.
