Proven waste to electric technology – gasification.

wastelectric is our future’s answer to cleaning up the way we put out the trash! What we have typically thrown in the garbage or our recycling bins, can now be converted into viable, green energy (electricity) or valuable products, such as ammonia, urea, nitrogen based fertilizers, and hydrogen.This in turn translates into money and jobs that feed our economy.

At wastelectric, we are recovering energy from waste through Gasification! Much of the abundant energy in our collection of waste goes untapped. Gasification is recovering this unused energy and converting it into green electricity. Not only are we reducing waste and eliminating our dependency on fossil fuels, but we are reducing the emissions of harmful methane gases and leaching of toxins into our water and soil; a thermal solution!

Imagine a world without toxic landfills. No more emissions of hazardous gas and taking up our much needed land that once landfills occupied. The numbers are impressive! A facility that treats 750 tons of municipal waste a day can provide enough power for up to 40,000 homes, while one ton of waste can create approximately 1.3 megawatts of power.

wastelectric is bringing waste project opportunities together with the appropriate funding partners, in order to most effectively collaborate on this astounding technology. This is an amazing opportunity to participate in an endeavor that is dramatically improving the health of our planet!

 

Gasification:

Gasification is an advanced conversion technology (ACT) that provides an environmentally friendly opportunity for municipality and business waste producers to convert their waste into Thermal Energy. The “energy” generated can provide heating and electricity along with many other benefits.

ACT is a process that operates within a oxygen deprived environment subjecting waste to temperatures of approximately 500 degrees celsius for up to 16 hours to enable and achieve 100% degradation of the waste to “white ash”. The waste in the first phase or Primary Cell conversion (Wt-Gas) process produces SYN-Gas that is collected and transferred to the Thermal Reactor or Secondary Cell where it is fired at high temperatures of 1,200 plus degrees celsius producing Thermal Energy. High temperatures are transferred to a heat recovery boiler for the production of high temperature high-pressure steam, which is used to drive steam turbine electrical generators and thermal energy distribution and utilization.

 

A Sustainable Solution with Environmentally Superior Benefits:

  • Enables waste 100% total resource utilization and up to 100%
  • Landfill diversion.
  • Recovers all recyclable materials
  • Converts residual waste after recycling into syn-gas for firing to produce renewable energy.
  • Reduces HAP’s (hazardous air pollutants) by up to 99% as compared to firing of fossil fuels.
  • Reduces millions of tones of fossil fuel consumption and dependence upon natural resources.
  • Reduces millions of tones of CO2 – greenhouse gas emissions.
  • Qualifies for renewable energy grants and carbon credit trading.
  • Provides one of the cleanest non-nuclear fuel thermal type energy sources known to mankind.
  • 100% Pathogen Destruction.

 

Process Description – The syn-gas production:

The Advanced Conversion Technology Chamber receives the waste derived fuel (WDF) and heats it to the required temperature in an oxygen-deprived environment. (Sub-stoichiometric) The thermal degradation process used is low temperature gasification – as it approaches semi-pyrolysis with condensable gases and some vapors being produced, the organic material within the solid feed is converted into a volatile and energy rich gas with properties similar to that of methane, and is referred to as “SYN-gas”.

Of significance to environmental management is that the gasification process produces the valuable non-fossil fuel resource of SYN-gas in an environmentally sustainable thermal process. The volatile constituents of the SYN-gas have very high energy content and as such are utilized downstream in the process for energy generation. Significantly, the SYN-gas is a relatively clean gas as heating and gasification is conducted in quintessential and low velocity conditions that minimize entrainment of pollution concerns.

In summary, the SYN-gas is a volatile and energy rich combustible gas and is used downstream in the process for high efficiency energy generation.

 

Pyrolytic Gasification Chamber:

  • Receives the waste or biomass and subjects it to low temperature-substiochiometric gasification; so as to heat and convert it into methane like gases high in CO, CH4 & CnHn hydrocarbons, which are referred to as syn-gas.
  • The process is around 1/20th the air input and around 1/50th the velocity and turbulence of conventional combustion, that maximizes the volatility of the syn-gas, plus minimizes entrainment of pollution concerns into it.
  • This results in the syn-gas being a relatively clean gas that’s available
  • for immediate utilization without further refining or treatment.
  • The feedstock of the gasification process is subjected to regular churning and stoking by a Churning, Stoking & Distribution System so as to expose all matter to the actual gasification process.
  • The feedstock is processed over a period of around 16-24 hours to ensure complete gasification.

 

Process Description – The Syn-Gas Burner:

First Air Quality Control Stage:

The SYN-gas Burner receives SYN-gas produced by the Advanced Conversion Technology (gasification) and fires it instead of fossil fuels. Due to its high-energy content it can be utilized in the same way as fossil fuels, including firing of boilers, gas engines and if refined then to fire gas turbines, fuel cells, etc. In this case the SYN-gas Burner (a technologically advanced high efficiency and low NOX gas-burner device) is used to fire the SYN-gas at temperatures of 1,200 plus degrees C.

For the 1st air quality control stage the resulting high temperature and “clean” off-gas is subsequently retained at high temperature with adequate retention in a Thermal Reactor so as to maximize destruction rate efficiency of principal organic pollutants, mainly dioxins and VOC’s.

The SYN-gas Burner firing results in an untreated off-gas that is environmentally superior to firing of many conventional fuels – Diesel, fuel oil, coal and wood, even natural gas.

 

Second Air Quality Control Stage:

The above-mentioned firing of SYN-gas produces an untreated off-gas that is environmentally superior to firing of conventional fossil fuels; however, so as to comply with stringent regulatory environmental regulations and provide minimal environmental impact a 2nd Air Quality Control Stage/System is provided to minimize solid and gaseous emissions.

 

Energy Utilization Stage:

The SYN-gas is fired at temperatures of 1,200 plus degrees C, thus a significant heat energy source is available for utilization. An Energy Utilization Heat Exchanger or steam boiler receives the off-gas produced by firing of the SYN-gas and utilizes the heat energy for steam generation which is subsequently utilized downstream for steam turbine electrical power generation.

The environmental analysis for the firing of SYN-gas and subsequent steam generation is environmentally superior to most any other form of its use.
