Herein, we provide eco-friendly and safely operated electrocatalytic methods for the selective oxidation directly or with water, air, light, metal catalyst other mediators serving as only oxygen supply. Heavy metals, stoichiometric chemical oxidants, harsh conditions were drawbacks of earlier oxidative cleavage techniques. It has recently come to light that a crucial stage in deconstruction plastic waste utilization biomass is activation inert C(sp

In liquefied natural gas (LNG) power plants, a significant amount of heat and cold energy is consumed to capture store carbon dioxide (CO 2 ) emitted during the combustion fossil fuels. The proposed system addresses this problem by utilizing temperature difference between waste as source generate electricity. study, novel recovery for postcombustion LNG plant was developed using an organic Rankine cycle (ORC). To design system, process model with following five parts: (i) vaporization, (ii) combined (NGCC), (iii) amine scrubbing, (iv) CO liquefaction, (v) injection. used lean cooling liquefaction. pressurized meet injection pressure requirements. ORC uses high-temperature exhaust from NGCC high-pressure sink. economic feasibility demonstrated assessment, net profit evaluated sensitivity analysis considering variations in water, electricity, equipment costs. Consequently, exhibited 18.6% increase production compared conventional system. addition, 76.7% confirming its feasibility.

Ammonia-soda process, which produce soda ash, emits flue gas containing a large amount of CO2 and SOx. The wastewater discharged from the ammonia-soda process contains cations, such as Na+ Ca2+, can be recovered reacted with In this study, we designed SOx utilization for sustainable production sodium carbonate using recovery system, extracting Ca2+. proposed involved following steps: (1) metal-ion separation, produces NaOH Ca(OH)2; (2) capture (3) Ca(OH)2, respectively. economic feasibility was verified by comparing its total annualized cost (TAC) those conventional processes. Approximately 99% captured to high-purity desulfurized gypsum, transformed into CaCO3. To confirm reduction carbon dioxide equivalent (CO2e) calculated evaluating greenhouse gases. CO2e decreased 71.4% compared that process. TAC 10.67% 19.63% Hou processes, Thus, study proposes an industrially potential design utilizing recycling, without additional reactants, making it more economically viable.

Many countries discharge considerable amounts of desalination wastewater directly into the ocean, which cause environmental pollution, destruction ecosystems, and economic losses. Desalination contains valuable metal ions such as Na+, Ca2+, Mg2+, react with carbonate sulfate ions; therefore, it has high potential to reduce NOx, SOx, CO2. Thus, this study designed process for utilization capture utilize CO2 using NH3. A model was developed, composed following three steps: (1) ion separation in based on pH swing processes separating Ca2+ Mg2+ Ca(OH)2 Mg(OH)2, respectively; (2) NOx SOx generated (3) Subsequently, demonstrate validity suggested process, an assessment conducted total annualized costs (TACs) conventional proposed were compared. As a result, ~96 % captured, efficiency 99 %, ~94.7 captured. reduction 11.2 TAC achieved indicating its feasibility.
