It is now globally agreed that renewable energy is one of the major mechanisms by which base-load energy requirements of the future will be met. Collective efforts must be employed to ensure that the circular economy is fully implemented and precious resources are conserved in the form of renewable energy.

Organics Energy’s success in renewable energy project development is the result of commercial experience, technical expertise, detailed local knowledge and a comprehensive network of partners.

The Organics Range of flare stacks provides control over the combustion process in both elevated and enclosed flame burners. Air is mixed with the combustion gases after exiting the burner port to ensure a clean burn, especially when the flow rate is reduced or the quality of the methane is below the optimum value for clean combustion.

The enclosed range of flare stacks controls heat loss to the environment and holds the gases at the design temperature for a specified period, referred to as the 'retention time'. Critical to a successful application of this approach to meet emission standards is control of the combustion air. This must provide homogenous conditions in the shroud, and is achieved by means of efficient mixing of fuel gas and combustion air within the combustion chamber.

Thermally-driven ammonia recovery was developed by Organics to offer an alternative route to that of pH adjustment for continuous-process ammonia recovery.

With a thermally-driven stripper no chemical additions are required, apart from the minor addition of anti-foam agent. The single important input is waste-heat with which to drive the chemical reactions.

If waste-heat is not available, the fuel-cost can be as prohibitive as that of chemical additions or carbon source requirements. Where waste-heat is available, from an engine-exhaust or unwanted biogas, the long-term operating cost can be confined to plant operation and maintenance, including electricity costs.

Biogas is a by-product of the anaerobic decomposition of biodegradable waste, either in a landfill site or an engineered anaerobic digestor. In its original state, biogas typically contains 50 - 60% methane (CH4) with a relatively high energy content of 36 megajoules (MJ) per cubic meter of CH4.

Methane is also a potent greenhouse gas with 25 times the global warming potential of carbon dioxide (CO2). An estimated 8 percent of global methane emissions released into the atmosphere comes from landfills alone. If biogas is captured and used for energy production, not only are these emissions reduced but a non-conventional source of energy displaces traditional fossil fuel use.

Organics has designed, constructed and delivered hundreds of biogas control and utilisation projects around the world. Download our datasheet to find out more about our services.
