“…In turn, cold energy from liquefied natural gas reduces the cost of maintaining the required temperature for the hydrate formation process. These options undoubtedly increase the hydrate formation’s energy efficiency and make it competitive with well-developed techniques [ 11 , 12 , 13 , 14 ]. However, such solutions can decrease the hydrate gas capacity, need promoter regeneration/water remediation, and significantly complicate the apparatus for continuously producing hydrates, especially at high pressures.…”

Three-Dimensional-Printed Polymeric Cores for Methane Hydrate Enhanced Growth

et al. 2023

Polymeric models of the core prepared with a Raise3D Pro2 3D printer were employed for methane hydrate formation. Polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), carbon fiber reinforced (UltraX), thermoplastic polyurethane (PolyFlex), and polycarbonate (ePC) were used for printing. Each plastic core was rescanned using X-ray tomography to identify the effective porosity volumes. It was revealed that the polymer type matters in enhancing methane hydrate formation. All polymer cores except PolyFlex promoted the hydrate growth (up to complete water-to-hydrate conversion with PLA core). At the same time, changing the filling degree of the porous volume with water from partial to complete decreased the efficiency of hydrate growth by two times. Nevertheless, the polymer type variation allowed three main features: (1) managing the hydrate growth direction via water or gas preferential transfer through the effective porosity; (2) the blowing of hydrate crystals into the volume of water; and (3) the growth of hydrate arrays from the steel walls of the cell towards the polymer core due to defects in the hydrate crust, providing an additional contact between water and gas. These features are probably controlled by the hydrophobicity of the pore surface. The proper filament selection allows the hydrate formation mode to be set for specific process requirements.

“…SCHs are attractive as gas separation media because of their high selectivity and stability. − Selectivities of SCHs for CO 2 /N 2 gas mixtures range from 3 to 40, depending on conditions of temperature, pressure, type of promoter, and their concentration . In the simulation of CO 2 recovery from flue gas (CO 2 /N 2 ) by SCH slurries, setting a two-stage process with CO 2 /N 2 selectivities of 30 and 40 resulted in a CO 2 recovery cost of $35/ton-CO 2 , which was below the goal of the U.S. Department of Energy ($40/ton-CO 2 in 2025) . However, in the simulation of systems that use the theoretical maximum absorption (H 2 O/CO 2 = 38:3) with TBAB for CO 2 capture, a significant amount of energy is required to cool the slurry, which is related to the amount of heat that forms during SCH formation and SCH dissociation.…”

“…The same amount of heat in the reaction is produced with opposite signs, so integrating the heat requirements for the process can improve energy efficiency . In the process simulations, operating pressures have ranged from 1.6 to 3.1 MPa. − Gas separation simulations have shown that the compression process consumes the most energy among configurations at high-pressure (>2 MPa) conditions . Lowering the operating pressure can be expected to reduce the energy consumption in SCH-based CO 2 capture systems.…”

Hydrate-based carbon capture technology offers simple operation and adaptation to small-scale regional biomass systems. Absorption of CO 2 by tetra-n-butylammonium bromide semiclathrate hydrate (SCH) slurries was investigated with a temperature-swing bubble column to elucidate clathrate formation mechanisms. At a constant temperature (278 K), the amount of CO 2 absorbed into the hydrate phase was 0.43 mmol-CO 2 /mol-H 2 O at 0.15 MPa CO 2 partial pressure. When the temperature was lowered to 276 K and held constant for 30 min, the amount of CO 2 absorbed increased (1.25 mmol-CO 2 /mol-H 2 O). When the temperature was raised to 278 K and held constant for 30 min, the amount of CO 2 absorbed decreased (1.08 mmol-CO 2 /mol-H 2 O), which was attributed to preferential decomposition of SCH with low CO 2 occupancy, because these particles have low thermodynamic stability. CO 2 absorption capacity in SCH slurries in bubble columns can be doubled by temperature swing since SCH dynamic formation with CO 2 absorption is faster than CO 2 absorption in existing SCH.

“…The most critical one is that the process has a high energy consumption requirement that is equal up to the 30% of power plant’s produced energy, resulting in a CO 2 capture cost of 40–100 $/ton and rise in electricity price of 50–90% [ 8 , 9 ]. This forced the world’s chemical engineering society to design new energy efficient processes that agree with the modern green chemistry principles [ 10 , 11 , 12 , 13 , 14 ].…”

The present paper deals with the complex study of CO2 capture from combined heat power plant flue gases using the efficient technological design of a membrane cascade type of «Continuous Membrane Column» for binary gas mixture separation. In contrast to well-known multi-step or multi-stage process designs, the cascade type of separation unit provides several advantages. Here, the separation process is implemented in it by creating two counter current flows. In one of them is depleted by the high-permeable component in a continuous mode, meanwhile the other one is enriched. Taking into account that the circulating flows rate overcomes the withdrawn one, there is a multiplicative increase in separation efficiency. A comprehensive study of CO2 capture using the membrane cascade type of «Continuous Membrane Column» includes the determination of the optimal membrane material characteristics, the sensitivity study of the process, and a feasibility evaluation. It was clearly demonstrated that the proposed process achieves efficient CO2 capture, which meets the modern requirements in terms of the CO2 content (≥95 mol.%), recovery rate (≥90%), and residual CO2 concentration (≤2 mol.%). Moreover, it was observed that it is possible to process CO2 with a purity of up to 99.8 mol.% at the same recovery rate. This enables the use of this specific process design in CO2 pretreatment operations for the production of high-purity carbon dioxide.
