Gasifiers Crude & Clean
Gasification is the process of extracting maximum amount of energy from combustible materials like coal, biomass and other carbonaceous materials through heating in an environment of controlled oxygen. The insufficient supply of oxygen allows the material to combust, thereby, producing quality producer gas. However, in order to extract more usable producer gas, the carbonaceous material should contain moisture content in it or artificial steam should be supplied from outside.
These days, coal usage has become widespread among manufacturing industries worldwide. The availability of coal reserves is much higher as compared to oil and gas reserves, which is the major reason behind the increasing use of coal gasification technology. Moreover, the increasing price of petroleum product like diesel, furnace oil, kerosene etc has made coal-firing as primary choice, a relatively less expensive carbon-containing material.
CASE Group understands coal as an excellent material to compete against other fuels more effectively. Therefore, the company offers state-of-art gasification technologies which are more environment-friendly and efficient for a number of industrial applications.
CASE Coal Gasification Process
CASE coal gasifier carbonaceous material undergoes four processes:
- 1. Drying & Charge Pre Heat: The producer gas flowing upstream through the reactor dries up the newly injected coal, thus making the next stage (Pyrolysis) easier and efficient.
- 2. Pyrolysis: Sometimes, called de-volatization, the condition occurs when the heated coal releases char and volatile resulting in up to 70% weight loss for coal. The volatiles being light in weight move upwards and the char moves downstream for the next process (Reduction).
- 3. Reduction: In this step, the char is acted upon by the Carbon dioxide and steam generated from the final process of gasification (Oxidation). Here the carbon dioxide and steam combines with char to give Carbon Monoxide and Hydrogen.
- 4. Oxidation: This is the final step of gasification where the reduced carbon (char) is burnt by blowing controlled air into the reactor. During this process, steam is injected simultaneously so that carbon gets oxidized in the presence of steam to generate Carbon Dioxide and Hydrogen.
Hot Gas Station
Crude Gas Station
We have successfully installed over 200 Gasifiers in steel industry, the application being majorly for Reheating Furnaces for Rolling Mills.
DRI Rotary Kiln
CASE in its endeavor to provide gasifier technologies, introduces the replacement of coal fines used in Rotary Kiln to coal gas.
Cold Gas Station
Pyrolysis Clean Gas Station
Pyrolysis Clean Gasifier works on the principle of partial combustion of coal thus producing primarily Carbon Mono Oxide called Producer Gas and further cleaning of gas.
Double Stage Gas Station
As the name suggests…. in this type of gasification technology there are two levels of gasification taking place. The first is the lower level gasification, which is that of Carbon in the coal...
