Johnson Controls sees rising interest in NH3/CO2 in Korea

2019-4-19 · "Korea is one of the signatories of the Kigali Amendment," remarked Kai Lee, Johnson Controls' technical support lead. "So we have to phase down HFCs. HFOs are one solution but we are talking about low-temperature applications. In terms of low-temperature applications, HFOs are not a good solution at this point in time."

Pumping CO2 Deep Under The Sea Could Help Korea Hit Net Zero

May 11, 2021 · South Korea’s plan helps “geotechnical stability” because pumping CO2 back into the subterranean rock strata would balance the loss of the extracted gas, said Kwon Yikyun, a geo-environmental sciences professor at Kongju National University, who’s working on the Donghae feasibility study. The technique has been used previously by the energy industry to force out crude oil or gas …

Physical property changes of sandstones in Korea derived ...

Laboratory experiments and calculation of the dissolution constant were performed to investigate the physical property changes of sandstones in Korea resulting from the geochemical reaction of CO2 under sequestration conditions. To simulate the sub-surface storage condition (100 bar and 50 °C), the high pressurized stainless cell and chamber were used and the supercritical CO2 fluid was ...

Solubility of CO2 in Aqueous Methyldiethanolamine Solutions

For 5.0, 20.5, 50.0, and 75.0 mass % methyldiethanolamine (MDEA) aqueous solutions, solubilities of CO2 were measured at 323.15, 348.15, and 373.15 K, respectively. Isothermal absorption capacities of CO2 as a function of MDEA concentration are presented. Lastly, the absorption enthalpy of CO2 in 50.0 mass % MDEA solution was calculated to be 54 kJ·mol-1 CO2.

Prediction of CO2 solubility in multicomponent …

abstract = "Prediction of CO2 solubility in electrolyte solution is important for the design of various industrial processes using CO2. A large amount of experimental data is needed to predict the solubility accurately, as a consequence of the complex composition of electrolyte solution. 1384 experimental CO2 solubility data in various electrolyte solutions (containing mostly Na+, Ca2+, Mg2 ...

2018-1-1 · Also, it does not require CO2 pre-separation which accounts for 70-75% of the cost of CCS chain. (Sanna, Uibu, Caramanna, Kuusik, & Maroto-Valer, 2014). It can sequestrate CO2 using the chemical reaction of CO2 with an alkaline solution or metal oxide. One of the examples of CO2 mineralization is the SkyMine® project ex cuted by Skyonic Co.

9 New Ideas to Cut Carbon Emissions | Audubon

The Idea: Fertilize grasslands with composted cow manure and plant waste.The Marin Carbon Project wants farmers to apply the organic mix to their pastures to vastly increase their ability to act as carbon sinks.. Why It Might Work: By composting cow manure in giant digesters, farmers can keep the smelly stuff from emitting methane—a greenhouse gas 30 times more potent than CO2.
