How to
Recapture
Energy:

To change most forms of energy into another form requires heat. The method that has been used for many years is known as "gasification." However, there are issues with every one of the gasification units currently in use today.

The Problems:

  • Current units require clean-up. This means stopping the unit and flushing it with water to remove the ash and other materials that collect during the process of gasification. This results in downtime, and contaminates the ground.
  • Current units can only gasify one type of waste at a time in order to achieve a consistent end product. Most current units develop ethanol; a low-energy fuel.
  • All require some electrical energy during operation, and in generating electrical energy they exhaust pollutants into the atmosphere.

Our gasification system can gasify any hydrocarbon or any combination of hydrocarbons (municipal solid waste). The EDCI system is capable of creating syngas and/or liquid fuels, such as jet fuel, diesel fuel, and others... all sulfur-free.

This new system:

  • Puts nothing harmful into the ground, air or water, from the waste feed stock.
  • Is designed to operate 24 hours a day, 7 days a week.

Usable Waste:

EDCI Clean Energy Solutions are based upon "modular engineering design concepts" with built-in redundancy of key modules, and common maintenance and replacement parts which limit down-time and maintain nearly 100% energy production capacity.  Key technologies comprising EDCI Clean Energy Solutions involve:

  • pre-processing of variable waste or other organic feedstock (e.g. coal, municipal solid waste, agricultural and animal waste, sewage sludge, used tires, waste plastics, medical waste, etc.);
  • pyrolysis of single or multiple streams of organic feedstock resulting in the production of synthesis gas (CO and H2) and inert residue;
  • processing the synthesis gas into either liquid fuels (through a series of catalytic reactions) or into electricity (through combustion in a turbine or engine); and
  • processing the inert residue from the pyrolysis process into usable products (e.g. aggregate for fertilizer, building materials, etc.)
     

Landfill Bio-Reactor Summary

  • Every landfill is unique. Its age, size, trash depth, annual rainfall, and the percentage of buried organics all play a part in the gas extraction volume and the total amount of time it takes to deplete all the organics from the landfill.
  • EDCI can harvest landfill gas to supplement gasification process while reducing methane emissions.
  • Minimize cost by using portable collector tubes.


Gasification Technology:

EDCI gasification is a simple, safe, efficient industrial waste treatment process that substantially reduces the weighted volume of the gasifying media, and destroys all hazardous effluents and emissions.

This closed-loop process (permitted in California and by the EPA) requires no additional emissions control, even where local air quality regulations are excessively demanding--and the residual ash is safe to discard in municipal waste or fill dirt. The residual ash is composed primarily of silica compounds (grit and sand) and common minerals (Al, Ca, Cu, Na, Mg, Fe, etc.), and is ideal as an additive to cement and fertilizers.

The system safely disposes of all waste, no matter how contaminated, by indirectly heating the feedstock chamber (while under vacuum) to approximately 1000 fahrenheit. The chamber is automatically maintained at a constant negative pressure to ensure efficient gasification.

A high-pressure blower sends the gasified volatile organic compounds(VOC) and other gases directly to a holding tank or a combustor, where they're mixed with the incoming fuel source and are used as fuel while being destroyed in the burner flame. These gases are then streamlined into and held at the burner flame's highest temperature zone, ensuring complete combustion. The process recirculates combustible gaseous products directly into the combustor, providing partial self-fueling of the process, and/or storing the extra combustible gases for future fuel requirements.

Technologies
for a W2E Project:

  • Gasification System: Gasifies the waste streams to create syngas.
  • Slurry Reactor: Converts the syngas into liquid fuels. Dryer: Dries the waste stream (if necessary) before gasification.

Technologies in Development

  • Hyperbaric Compressor: Supplies high pressure for gasification efficiency.
  • Variable Speed Alternator: Provides a constant frequency of electrical power at variations of speed, as waste streams and demands for electrical power fluctuate.
  • High Pressure Engine: This comes in two forms, both of which function at a pressure range that provides enough oxygen to burn all the fuel in the combustion chamber, thus operating pollution-free.
  • Turbine Engine: For the generation of electrical power in support of the grid.
  • Piston Engine (2 megawatts): For the generation of electrical power in support of small communities, hospitals, military outposts and shopping malls.

Requirements for Project Initiation:

  • Secure long-term access to waste stream
  • Secure site needed for operation
  • Permitting (i.e., meet all necessary government requirements and regulations)
  • Secure buyers for produced commodities (e.g., electricity, liquid fuels, etc.)
  • Arrange needed funding
  • Fabricate and install
  • Operate and expand the facility

Retrofitting:

Existing facilities can be retrofitted with new gasification technologies, saving the time and expense of creating brand new facilities.
