Renewable Energy From Solid Wastes With Gasification
Gasification conserves the chemical energy of waste in the syngas produced. The process accepts a wide range of waste and produced purified syngas as well as granulates metals and minerals that can be used in industry and construction.
The thermo chemical conversion changes the chemical structure of the biomass by means of high temperature. The gasification agent allows the feedstock to be quickly converted into gas by means of different heterogeneous reactions. The combustible gas contains CO2, H2,CH4,H2O, trace amounts of higher hydrocarbons, inert gases present in the gasification agent, various contaminants such as small char particles, ash and tars.
A gasification system is made up of three fundamental elements:
The gasifier, useful to produce the combustible gas
Optimize Kinetik
The gas cleaning system, necessary to remove harmful compounds from the combustible gas
The energy recovery system
The system is completed with suitable sub-systems useful to control environmental impacts (air pollution, solid waste production and wastewater)
