Topic: Social Economy to Affordable Energy

Problem:
Conventional Flaring is defined as a process of controlled burning of exhaust gases which generates heat and noise. Flaring is a common practice in oil/gas exploration, production and processing operations. Flare stacks emit a lot of emissions and much more energy is wasted in this whole process, if we save the energy being wasted from all the flares stacks of the refineries across the globe we can power a whole continent: Africa.

Solution:
HiTAC or High Temperature Air Combustion uses a combustible mixture with a low oxygen concentration which is preheated by recycling the heat from the flue gases. Like that, HiTAC highly reduces heat losses. Instead of air, HiTAC can even use flue gases enriched with oxygen. HiTAC is the perfect technology to solve this problem, because it works better with high temperature gases which are exactly what feeds the flare stacks.

The HiTAC technology can provide:

  •  Enlarged flames;
  • Stable and homogeneous flames;
  • Low NOx emissions.

The differences in the flame include increased thermal field uniformity in the combustion zone, high efficiency and reduced emission of pollutants with HiTAC. The HiTAC furnaces have the following advantages: significant energy savings (reduced fuel consumption), low environmental impact, NOx emission reduction, efficient and stable combustion, enhanced heat transfer and reduced combustion noise.

Scope & Objective:
The scope of this project is to address the energy wastage and reduction of amount of emissions from the flare stacks, by high performance, low fuel consumption, very low emission of NOx, CO, soot, hydrocarbons, CO2 and other greenhouse gases. Furthermore, low heating value fuel can be utilized without any auxiliary fuel. Smaller size of the furnace for performing the same function means savings in materials and resources. This in turn means further energy savings and pollutants reduction. This technology has been shown to provide large energy savings in industrial furnaces and power systems.

Furthermore, the heat emitted from the furnace can be incorporated in the power generation cycle to use this heat efficiently, which can be further used for different energy applications such as heating applications, air conditioning cycles and combined heat power cycles.

Addressee:
As mentioned above the addressee of this project will be the oil/gas exploration plants, production and processing plants such as refineries, chemical process plant and landfills. The surplus energy produced by this project will be provided to the community, also providing better air quality to the population in the vicinity.
