Sulaway versus Amine plant Flow scheme
Sweetening of sour gas
An amine plant is a cheap investment, but extremely expensive in production and maintenance.
Extra investment costs due to process equipment:
- Two (2) heat exchangers
- Two (2) pumps
- Steam boiler
- Reflux drum
- Basic material Amine
- Consumption of steam and water
- Sulaway decreases costs by transforming H2S in sulfuric acid (H2SO)
Maintenance costs daily for amine plant
- Sulaway plant checkup each half year for gas compressor.
- The cleaning process of biogas using a amine plant, is not an acceptable process on agricultural land due to the heavy sewer water pollution
