H2S Chemical Scrubber
KEY FEATURES
Cleaner less corrosive gas
Instant start up after plant shutdown
Reduced engine downtime for maintenance
PRODUCT OVERVIEW:
Consumables: Sodium hydroxide, electricity, water
Discharge: Wastewater
The process
Our H2S Chemical scrubbers are particularly effective on sites with a medium to high H2S loading. The single stage, counter-current, process uses sodium hydroxide, also known as caustic soda, to reduce the content of hydrogen sulphide in the biogas.
The raw biogas flows upwards through the media packed vertical tower. Simultaneously, the recirculated sodium hydroxide solution is sprayed downwards through the media, absorbing the hydrogen sulphide (H2S) from the biogas.This process is reliable and efficient and you will have cleaner, less corrosive biogas as a result.
Other benefits include:
- small footprint
- well proven process
- easily retrofitted
- instant start up after plant shutdown
- ideal for variable H2S loadings
