The output material (product(s))of TCG plant
The output material (product) of the TCG technology is a combustible SynGas that contains hydrogen, carbon monoxide, carbon dioxide, methane ( H2, CO, CO2, and CH4 ) and in miniscule quantity other gases. The produced SynGas is an excellent feedstock material for electricity generation in gas motor/generator sets, and for the Fisher-Tropsh syntheses based processes to produce important liquid fuels such as ethanol, methanol, diesel and Jet Fuel.
To produce synthetic natural gas (SNG), electricity, hydrogen and liquid hydrocarbon fuels, the SynGas is further processed in specially designed and built downstream facilities.
Synthetic natural gas (SNG)
The SynGas is subjected to a methanation process in a downstream plant that produces synthetic natural gas (CH4). The SNG when burned in gas motors emits 50 – 60 % less toxic or harmful gas (CO2) than natural gas.
Electricity
The SynGas when utilized (burned) in gas motor/generator sets is converted to electric power (electricity with tenth of MWe capacity) with very high efficiency. Since the input (feed) material into the TCG plant can be municipal solid waste, the overall economic of such a power generation system can be very high because the “input material” can be very inexpensive or, in many cases the municipalities pay for the power plant to take over (dispose) the waste for power generation.
Heat power
The modern gas motors and turbines are fully furnished with auxiliary systems that collect the waste heat energy during combustion with very high efficiency. The collected and usable (waste) heat energy can be significant, several MWh of energy that can be utilized for district heating, or in industrial and agricultural heating systems.
Liquid hydrocarbon fuels
The produced SynGas subjected to specifically designed and built plant(s) to Fisher – Tropsh (FT) synthesis processes to produce liquid hydrocarbons (fuels) such as diesel, kerosene, methanol, ethanol, etc. The TCG produced SynGas is uniquely qualified for FT processes due to its cleanness and best suited compositions.
Hydrogen
The TCG plant can produce SynGas with set gas composition with high efficiency and accuracy. Consequently due to the flexibility of this technology, it is possible to set the produced gas composition in such a way that the hydrogen (H2) content in the produced gas is as high as 80 – 85% (or even higher). This is one of the very highly appreciated advantages of the TCG plant.
The picture below depicts a TCG system whose SynGas product can be utilized for further processing or utilizing for many different final products. The electricity and heat energy (including waste heat) can be utilized in a wide range of industries in addition to heat energy to district heating or the plant’s offices:
