CO2置换可燃冰(natural gas hydrates,NGH)是传统NGH开发模式的主要方法之一[58]。CO2进入CH4水合物系统中后,会建立新的平衡体系,CO2将置换CH4,并以水合物的形式封存于地下(图1),有效避免可燃冰开采过程中地质结构的变化带来不利的影响,从而实现...
The plate-fin heat exchanger (PFHE), which has been widely used in natural gas liquefaction (LNG) industry at present, has some disadvantages such as being sensitive to the impurities in the feed gas, such as water, CO 2 and H 2 S. Compared with the PFHE, the brazed plate heat ...

Carbon dioxide liquefaction technology provides environmental and operational advantages. Recovering CO2from biogas upgrading, prevents atmospheric release, reducing greenhouse gas (GHG) emissions. This technology also produces high-quality, food-grade bioCO2, a valuable resource for industries like food and...
coalbed methane contains high amounts of CO2that induce solidification during liquefaction. Therefore, CO2has to be reduced below 2% to meet the pipeline transportation standards. In addition, CO2capture would reduce the amount of gas emissions to the atmosphere, thus mitigating global warming. Here,...
Our sensitivity analysis showed that the change in hydrogen cost had the greatest effect on overall cost for LSM, which varied from ~US$21–48/GJ when the hydrogen cost varied by ±50% ($1.2–3.6 per kg of H2). The capital costs for liquefaction and DAC were the next major components,...
CO2 liquefaction Hot energy Cold energy 1. Introduction In many countries, natural gas (NG) is regarded as the fastest growing energy resource, owing to its considerably lower air pollutant emissions, such as CO2, SOx, and NOx, compared to other fossil fuels [1], [2], [3]. In general,...
