Demonstration of a Technology to Clean Raw Biogas for Electricity Generation

Demonstration of a Technology to Clean  Raw Biogas for Electricity Generation


The research aims to identify and demonstrate suitable technology to clean raw biogas for use in generating electricity. Preliminary results indicated that the project was viable and gas of sufficient concentration could be produced for electricity generation. A new digester was fabricated and delivered to Copperbelt University. However, an impurity of concern is Hydrogen Sulphide (H2S) gas which is not only a pollutant but is also corrosive to pipes, machine components and vessels. Consequently, the focus of current work is to desulphurise the biogas and a number of techniques are under evaluation.
