Control of H2S in the production of Biogas

H2S is a perennial problem for the production of biogas from the anaerobic digestion of organic material. Organics has a long track record in project management and the supply of equipment for environmental protection and renewable energy projects and H2S management is of supreme importance to ensure optimum operational conditions.

Our technology has been employed in many projects all over the world ranging from the supply of bespoke equipment to the design and execution of AD projects and turnkey systems. 

Tachang, Thailand

Project: Tachang, Thailand

This project involved the design, installation and commissioning of a closed lagoon bioreactor on the settling lagoon of a palm oil mill owned by the Sinar Mas Group, Indonesia’s largest palm oil producer.

The brief of the project was to treat the high levels of COD found in the Palm Oil Mill Effluent (POME) and to ensure that the methane gas produced could not escape to atmosphere and contribute to the greenhouse effect. 

The project commenced with the design phase and a period of testing to ensure that all parameters of the POME and the location were known before investment in the plant began. 

Project Specification

The project was designed to treat the palm oil effluent produced from the production of palm oil, one of the staple foods of Asia and a product used in many other products around the world.

It was designed to handle up to 3,000Nm3/hour of biogas, the equivalent of 4 MWe and enough energy to power the entire operation leaving an excess to export.

The lagoon was designed to accommodate 60,000m3 of wastewater from a factory that processes 80 tonnes per hour of Fresh Fruit Bunch.

 

Project Budget

Project budget of USD $4 million.

Project delivered within the specified programme and on budget. 

Features of CLBR POME
  • Proven Principle
  • Low construction costs
  • No internal baffles
  • High conversion efficiency through excellent internal mixing and high retention of anaerobic bacteria
  • Enhanced facility for periodic sediment solids removal from the lagoon reactor
  • Optional facility for floating scum removal and recycling
  • Internal gas storage for black starts
  • Enhanced cover design for high safety standards
  • Integrated storm water removal system
Advantages of CLBR
  • Proven technology with many sites constructed in SE Asia over the last 10 years
  • Low cost when compared with tank digesters
  • Corrosion resistant, low maintenance
  • Improvements on cover design with special emphasis on safety
  • Compact, integrated design of recycle and influent pumping station
  • Long hydraulic and solids retention time achieve excellent treatment efficiency of complex wastewater
  • No concerns on biomass retention
  • High process stability after shock loading
  • Versatile and adaptable to many different conditions
  • Use of durable and UV stabilized materials
  • Family of designs for specific purposes

PT Cam, Kendari, Southeast Sulawesi

Project: PT Cam, Kendari, Southeast Sulawesi

This project involved the design, installation and commissioning of a closed lagoon bioreactor on the settling lagoon containing wastewater from the production of cassava from tapioca at the PT Cam mill located in Southeast Sulawesi, Indonesia.

The brief of the project was to ensure that methane gas produced from wastewater treatment could not escape to the atmosphere and contribute to an increase in the greenhouse effect.

The project commenced with the design phase and a period of testing to ensure that all parameters were fully understood before investment in the plant began.

Project Specification

The project was designed to treat the palm oil effluent produced from the production of palm oil, one of the stable foods of Asia and a product used in many other products around the world.

It was designed to handle up to 3,000Nm3/hour of biogas, the equivalent of 4 MWe and enough energy to power the entire operation leaving an excess to export.

The lagoon was designed to accommodate 60,000m3 of wastewater from a factory that processes 80 tonnes per hour of Fresh Fruit Bunch.

 

Project Budget

Project budget of USD $5.5 million.

Project delivered within the specified programme and on budget. 

Features of H2S treatment
  • Treating biogas derived from POME
  • H2S bio-scrubber installation
  • Flow rate: 3,000 Nm3/hr
  • Inlet H2S: 2400 ppm
  • Outlet: <200 ppm

Tedco Agri Makmur, Bandur Lampung

Project: Tedco Agri Makmur, Bandur Lampung

The project included the design, installation and commissioning of a closed lagoon anaerobic bioreactor on the settling lagoon of a cassava mill; the Tedco Agri Makmur in Bandur Lampung, Sumatra.

The objective of the project was to treat the high levels of COD found in the mill effluent and to ensure that the methane gas produced could not escape to the atmosphere and contribute to the greenhouse effect. 

The project commenced with the design phase and a period of testing to ensure that all parameters of the wastewater and the location were known before investment in the plant began.
