Aries - Fluidized Bed Gasification System
Fluidized bed gasification is a process that converts carbon-containing waste material into a synthetic fuel gas, along with a very small amount of inert char. Waste feedstock is fed into the gasifier and a controlled amount of oxygen is introduced. Once necessary temperatures are achieved and maintained, a thermo-chemical process converts the biomass into a combustible syngas primarily composed of carbon monoxide, hydrogen and methane. That sustainable fuel can be deployed in a commercial dryer to remove moisture from biosolids. The system can cleanly reduce volume by as much as 95%.
Because our patented fluidized bed gasification technology consumes little oxygen and results in lower air emissions, it is an attractive alternative to conventional disposal processes such as burning or land application. In fact, the Environmental Protection Agency has specifically established that fluidized bed gasification is not classified as incineration.
Aries Clean Energy brings extensive experience in working with engineering firms, contractors, vendors, and financial entities to assist in the smooth integration of our gasifier into an overall biosolids treatment system. Siting facilities is easier than with alternative methods due to the clean emissions profile associated with our gasification process.
The most suitable feedstocks for the Aries Clean Energy fluidized bed gasification system are biosolids from municipal wastewater treatment plants, or biomass residues from certain types of industrial manufacturing and processing operations.
The primary use of syngas resulting from our fluidized bed systems is the reduction and disposal of biosolids utilizing conventional industrial gas-powered drying technology.
Our fluidized bed systems give customers a much more environmentally friendly method of biosolids disposal, and can lower their dependency on fossil fuels. Sustainability benefits for our systems typically can be found in:
- Achieving zero landfill and/or land application goals for industry and municipalities.
- Reducing carbon footprints. New green energy production measurably offsets former use of fossil fuels. A considerable reduction in trucking operations also contributes to reducing CO2 by thousands of tons per year. These carbon and greenhouse gas reductions are calculated using EPA standards.
- Enhancing the brand value of a community or an industry can be an integral element in the sustainability value of a gasification system.
Analyzing the financial benefits of a fluidized bed gasification project can be quite straightforward in many cases. In other instances, with multiple partners and cost/income centers involved, putting together the true financial picture becomes more complex.
From an economic standpoint, projects are almost always based on some combination of two benefit factors:
- Biosolids disposal cost reductions and offsets. These include not only tipping fees, but usually sizable transportation costs. There can be financial benefits in meeting government regulations and avoiding fines imposed for non-compliance in disposal practices.
- Energy (electrical or thermal) production and the value that brings in terms of offsetting current costs, as well as additional monetary value of utilizing sustainable/renewable power.
