Biogas Desulfurization

Company Description:

ECOTEC – Ecología Técnica, S.A. is a company with more than 30 years of experience in the environmental field.

Since their establishment in 1991, they specialized in industrial exhaust gases treatment and water treatment equipment design and manufacturing.

In recent years, and as a result of strategic collaboration agreements, ECOTEC has developed dBiox®: highly specialized solutions for the biological treatment of gases with very high content of H2S by bioscrubber and biotrickling filter.

In water treatment, they have launched innovative patents and technologies for lamella clarification systems, aimed at improving efficiency and reducing operating and maintenance costs.

ECOTEC’s main objective is to offer customers sustainable and reliable solutions at competitive prices and minimum operating costs.

Technology Description:

A bioscrubber comprises a biological system in two stages that facilitates the immediate absorption of contaminants in an alkaline medium, obtaining transfer efficiencies greater than 99% and thus achieving emissions of undiluted biogas free of H2S.

The Empty Bed Residence Time (EBRT) inside the scrubber is minimal, which leads to lower investment costs. Consequently, the H2S(l) is conducted to a bioreactor (liquid phase), where anaerobic microorganisms perform biological oxidation in alkaline pH.

These systems enable both an efficient and economical removal of H2S present in biogas in concentrations greater than 10,000 ppmv and flow rates up to 6,000 m3/h.

In order to maximize the effectivity of microorganisms, the equipment incorporates an advanced control system for air batching, as well as for temperature, redox potential, pH and nutrient control devices. The reclaimed water is subsequently recycled by the scrubber.

The consumption of reagents and water in this biological system is minimal, which reduces operating costs significantly compared to alternative technology.

A small flow of acidified liquid effluent is generated by using this process and it has applications in different industrial sectors without the need for additional expensive treatment. All operating parameters are continuously recorded and stored, which ensures that the installation is monitored effectively.

Technology Strengths, Weaknesses and Critical Indicators

NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.

General Support & Other:

  • Can be an integral part of many manure management systems
  • Most projects have at least some equipment that supports operations of the main technology
  • This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.

Newtrient Comments/Opinions:

Ecotec has recently been added to the technology catalog, Newtrient will continue to work with them to further refine the cost and performance information, publishing it and updating the 9-Point score as information becomes available and as new commercial dairy installations come online.
