1) LCO2 Recovery Plant from Carbon - contained Fuel

Basic situation of raw material being used: LNG, Oil like diesel, gasoline, Coal, Acid base neutralization or other source


2) Industrial emission sources

(1) Fossil fuel combustion flue gas

-Source: Coal/gas power plants, boilers, industrial kilns, etc.
-Characteristics: Low concentration of CO2 (usually 10% -20%), requiring pre-treatment (dust removal, desulfurization, denitrification, etc.), and high recovery cost.
-Technology: commonly used amine absorption methods (such as MEA), membrane separation, or low-temperature distillation.

(2) Chemical production process

-Source: Synthetic ammonia/hydrogen production: high concentration of CO2 in by-product gas (15% -30%).
-Ethylene production: The flue gas from the cracking furnace contains CO2.
-Cement production: The concentration of CO2 in the kiln tail gas is about 20% -30%.
-Characteristics: High concentration, relatively economical recycling.

(3) Refining and Steelmaking

-Refinery: Catalytic Cracking (FCC) unit emits CO2
-Steel plant: Blast furnace gas and converter gas contain CO2 (20% -30%).

(4) Biomass energy

-Bioethanol fermentation: The concentration of CO2 in the fermentation exhaust gas is nearly 100%, with extremely high purity, and can be directly liquefied and recovered.

3) High purity natural CO2 source

(1) Natural gas field

-Associated CO2: Some gas fields contain high concentrations of CO2 (such as Jilin Oilfield in China and Sleipner Gas Field in Norway), which can be directly separated and purified

(2) Geothermal well

-Some geothermal fluids contain CO2, such as the carbon capture project at the Hellishei ð i geothermal power plant in Iceland.

Biogenic sources

-Biogas: Anaerobic fermentation produces a mixture of CO2 (30% -50%) and methane, which needs to be separated.

-Biomass combustion: The smoke from burning wood or crops has a CO2 concentration similar to that of fossil fuels.
