Our Unique Position in India

Radhe stands apart with 65% of total installation of Gasification Technology

from the rest in India, as per the survey by Karnataka State Council of Science &

Technology and Submitted to DSIR (Department of Science and Industrial Research)

Gasification Reaction:C + O2 → CO2 (Combustion)C + H2O → CO + H2 (water gas)C + CO2 ⇄ 2CO (Boudouard Reaction)CO + H2O → CO2 + H2 (water shift Reaction) C + 2H2 → CH4 (Methane Reaction)

What is Gasification ?

producer gas compositions:Carbon Monoxide (CO) : 20 ±2%Methane (CH4 ) : 03±1%Hydrogen (H2 ) : 12±2%Carbon Dioxide (CO2 ) : 03±2%Nitrogen (N2 ) : 50±5%CV of Producer Gas : 1200-1350 Kcal/Nm3

Gasification is a thermo- chemicalprocess, which converts any solid

carbonaceous material intocombustible gases called

Producer / Coal Gas.

About Cold Gas Filtration & Cleaning Technology

Aim to Utilize Direct Clean and Cold Gas

Tar is being removed in ESP

Moisture present in producer gas is being removed in

both condensers.

Waste water is disposed by Evaporator.

Tar is utilized as a fuel in Sodium Silicate & Cement

industries having energy value around 7500 Kcal/Kg

Outlet gas temperature will be around 35-40°C

Fully automatic SCADA control system

About Hot Gas Filtration & Hot Gas Cleaning Technology

Aim to Utilize Direct Clean and Hot Gas

Tar is Remain In to gaseous Form & Utilize in

Furnace as a Fuel With Coal Gas

Outlet Temperature of Gas up to 300-450°C

Utilization coal as a Filter Media for cleaning of Hot

Gas which can re utilize easily with fresh feed coal.

Hot Filtration Technology operates fully automatic

with SCADA & Based On Pressure Drop
