Description

A SYSTEM AND METHOD FOR CAPTURING CARBON DIOXIDE (CO₂)

FIELD OF THE INVENTION

The present disclosure relates to a gas-liquid contact systems, methods, and solvents, including carbon dioxide capture system and method for the capture of CO₂.

BACKGROUND OF THE INVENTION

Energy is a crucial factor in the growth of any country. Rapid advances in industrialization and transportation have caused a significant rise in emissions from point and non-point polluting sources. Carbon dioxide emissions from the burning of fossil fuels cause global warming. To impact of climate change can be "cured" of the air pollutants by reducing the volume and concentration of CO₂ emissions must be decreased. From the pre -industrial revolution, around 1850, until 2022, the global average atmospheric CO₂ concentration increased substantially from 285 to 419 ppm, and we are currently going up at the rate of 2.5 ppm per annum. The United Kingdom meteorological office estimates a global average surface temperature increase of about 0.97 to 1.21 °C from 1850 to 2022. Carbon capture and storage (CCS) technologies target CO₂ removal from large fixed-point sources. CO₂ capture processes can be divided into three main categories: post-combustion, pre-combustion, and oxy-combustion. Post-combustion carbon dioxide capture is based on chemical absorption, a mature technology, and easily retrofitted to existing industrial plants. Absorptive CO₂ Capture (ACC) is widely embraced to mitigate CO₂ emission, but it is energy-intensive and expensive to implement commercially.

In the CO₂ capture process, the emissions from a process plant are passed through an absorber where the solvent absorbs the carbon dioxide. The solvent is then regenerated by heating in a regenerator to separate the absorbed CO₂. The solvent can be reused in the absorber, and the CO₂ gas is stored and sent for further utilization. Conventional plants for CO₂ are energy intensive. Hence it is necessary to reduce the energy consumption pattern of CO₂ capture using a novel eco-friendly solvent.

The CO₂ capture facility enables screening of efficient and low energy consumption capture of CO₂ using deep eutectic solvent (DES). The hydrophobic DES comprises a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD) in different molar ratios. The selection of ratio is based on its activity coefficient. The chemistry of the interaction mechanism between DES and CO₂ needs exploration. This facility provides a technical reference for applying new solvents developed in the laboratory to practical industrial processes. This setup is a part of research efforts to improve the solvent's CO₂ absorption capacity and reduce undesired product/contaminants formation with an optimal design process to operate at maximum efficiency.

C0₂ capture needs an effective and sustainable technology. The existing technology for CO₂ capture is based on various solvents and processes, such as amine-based solutions, amino acid salt, ammonia solution, carbonate solution, ionic liquid, microencapsulated and membrane absorption, nanofluids and phenoxide salt solution and phase changing absorbent, Amine- and NH₃-based absorbents are widely used but associated with high regeneration cost, corrosiveness, reagent loss and secondary pollution caused by NH₃ escape. Phase-changing absorbents are gaining attention due to their lower price and energy penalty. Adding nanoparticles to solvents could improve CO₂ absorption performance and reduce energy requirements.

Chemical solvents, such as activated MDEA, enable CO₂ removal and improves the purity of the produced CO₂-rich stream. The production of highly pure CO₂ if the carbon source is used to manufacture bulk chemicals. New, cheaper solvents need to be developed before the implementation of the laboratory studies. Special efforts are being made in the following areas: (1) Increasing reaction rates, absorption capacity, reducing solvent circulation rates and equipment sizes; (2) Reducing the reaction enthalpy and reducing regeneration energy required in the desorption process, and (3) Improving the thermal stability and resistance to oxidative degradation, reducing makeup solvents and extra process on solvent waste.

Lab scale and pilot scale tests of chemical solvents are critical in industrial applications. The most commonly used chemical solvents in carbon capture are amine solvents, categorized as simple alkanolamines and sterically hindered amines. Simple alkanolamines include MEA, DEA and MDEA (primary, secondary and tertiary amine) solvents. Recently cyclic diamines, especially piperazine (PZ), have been proposed to improve the performance of MEA as PZ enhances reaction rate, higher absorption capacity and resistance to thermal and oxidative degradation. Blending amines at different proportions also provides another degree of freedom to estimate the selectivity of the solvent, which can optimize separation performance and reduce the cost of the carbon capture process. Mangalapally and Hasse have tested novel solvent mixtures of PZ and carried out pilot plant trials.

Amino acid salt (AAS) based systems, like amine -based systems, capture CO₂ faster. AAS achieve high cyclic loading, have a high resistance to oxidative degradation, are environmentally benign and have low binding energy. Ammonia-based systems, including aqueous ammonia and chilled ammonia, are considered alternative solvents for CO₂ capture. Aqueous carbonate solutions, mainly potassium carbonate (K₂CO₃), have increased recently. Compared to amine -based solutions, K₂CO₃ solvent has several advantages. K₂CO₃ is less volatile, less corrosive, non-toxic and has minimum oxidative degradation. K₂CO₃ solutions can also capture S0_x and N0_x to produce fertilizers. Ionic liquids (IL) are gaining attention due to: Good thermal stability, high polarity, low CO₂ equilibrium partial pressure, and Non-toxicity.

A new class of ILs, Deep eutectic solvents, possess most of the properties of ILs and advantages in terms of economic benefits. DES-based choline salts are one of the promising solvents for CO₂ separation. The viscosity of the synthesized DESs is high and has a low mass transfer rate. The CO₂ solubility in the DESs needs to be enhanced. Water as a co-solvent for the glycerol-based DES will give high viscosity and offers scope for research. The physicochemical properties and water effects of choline -based DESs need comparison with those of conventional ILs. Traditional scrubbing towers are filled with structured packing, and a counter-current flow of gas to liquid is employed.

In the view of the forgoing discussion, it is clearly portrayed that there is a need to have a system and method for capturing carbon dioxide.
