Biological H2S removal is a danger for the environment

An amine plant is a cheap investment, but extremely expensive in production and maintenance.

H2S content from 10.000 up to 100 ppmV

Extra investment costs due to process equipment:

• Blower/booster compressor
• One (1) heat exchanger
• Sewage treatment plant to wash water

Production costs:

• Active coal 
• Extra electric power
• Water consumption
• Loss of methane (CH4)

Maintenance:

• Daily attention of biologicals
• Sulaway plant checkup each half year for gas compressor

Savings:

• Sewage water plant produces Sulphuric acid (4%)
• Sulaway decreases costs by transforming H2S in sulphuric acid (H2SO: 85%)
