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
• Re-boiler

Production costs:

• 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
