1. CO2 recovery plant from low-concentration CO2 feed gas
We cooperate with top university in CO2 capture filed in China. Our internationally patented advanced technology for low concentration feed gas does not adpot MEA solution, which enables clients to use the solvent without any replacement for 2-3 years. Our plant has lower electricity and steam consumption, easy operation mode and highest capture efficiency in the market. The solvent in the process does not corrode the pressure vessels and does not react with oxygen or CO2, which is much superior than the traditional MEA technology. There is no polluted residue after production in our process. This technology has more than 30 plants in operation up to 9 years both at home and abroad, which were installed in cement factory, steel plant, chemical factory, limekiln, etc.
2. CO2 recovery plant from high-concentration CO2 feed gasOur pioneering low-temperature distillation washing process can remove alcohols, aldehydes, ethers, and water with boiling points higher than that of carbon dioxide. This eliminates the need for water washing, potassium washing, molecular sieve drying, and other devices, making it a major highlight of this technology.
Unique measures for heat and cold utilization are employed, with key heat exchange equipment utilizing plate-fin wett technology, ensuring the temperature difference between cold and heat is precisely controlled within 1ºC, effectively reducing product consumption;
The only one in China that uses a cold box distillation unit, utilizing heat pump distillation and multi-stage refrigeration technology;
The fermentation tail gas enters the low-temperature condensation system directly from the main pipe (the original dilute alcohol recovery tower is disabled during production). The alcohol in the tail gas can be fully recovered, saving water and steam. Moreover, the selling price of alcohol is much higher than that of liquid carbon dioxide, and the recovered alcohol can greatly reduce production costs.
By using environmentally friendly and safe refrigerants, the investment in safety and environmental protection can be significantly reduced, and land use can be conserved.
We use advanced and reliable made-in-China CO2 compressors, instead of conventional compressors, improving the operational stability of the system; and the use of high-end industrial DCS control system enables remote control and unmanned operation on site.

Feed gas sources:
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.
