Organics Ltd provides engineering equipment that falls into two main categories: Environmental Protection and Renewable Energy. Their services include low emission flare systems, of which they have many hundreds of installation around the world, odor control, landfill gas extraction and utilisation, anaerobic digestion systems and advanced thermal processing (pyrolysis and gasification). They specialize in field and landfill engineering in particular.
Organics offers a range of standard waste-gas flaring and utilisation technologies designed to meet environmental controls. At the top end, the Organics SMART flare technology offers high temperature, extended retention time combustion, combined with exhaust gas recycling to minimise NOx formation mechanisms. The SC and MC Classes of flare are a basic tool for the combustion of landfill gas and biogas in Europe, the United States and Australia/New Zealand.
They provide varying degrees of environmental control to meet the varying standards of the countries involved and the environmental objectives of the end-user. The AC Range provides a no-frills combustion tool for locations where stringent environmental controls do not apply or where relatively clean gases are to be disposed of safely.
Simple elevated flares with visible flames and minimal control over the combustion process:
Shrouded flame flares with no visible flame and automated control of combustion air allowing a combustion temperature of 1,000ºC and 0.5 seconds retention time:
Shrouded flame flares which allow combustion up to 1,200oC and 0.5 seconds retention time:
Safe combustion of low calorific value gases.
The LHC (Low Heat Content) Range flare is designed specifically to address the problem of combusting gases with low calorific values, or heat contents. The optimisation of combustion control techniques ensures that heat loss is minimised, whilst air and gas mixing is maintained at a very high level.
In normal landfill gas flares, for example, the usual minimum methane concentration at which a flare will burn is around 15 to 20% methane. Codes of practice, indeed, suggest that combustion should be halted when methane drops below 20% to avoid the possibility of an explosion. The LHC Range flare is designed specifically to burn below 20%. It has inbuilt explosion protection measures and can operate down to as little as 5% methane in air.
Shrouded ground flares which, as well as allowing high-temperature combustion, include exhaust gas recycle to minimise the formation of NOx:
The Organics premier range of flares which, as well as allowing high-temperature combustion, include full facilities for exhaust gas recycle, combustion air staging and fuel-gas staging to minimise the formation of NOx:
