“…Roostaie and Leonenko , developed an analytical approach of wellbore heating coupled with hot water circulation and investigated the NGH decomposition behaviors in the reservoir. Yadav et al and Wang et al both proposed a microwave heating technology for NGH exploitation and found that this technology could significantly improve gas recovery and achieve a high energy efficiency. Despite the different methods used, the essential concept of these methods was to provide external heat to promote hydrate decomposition.…”

In this work, a new approach of seawater flooding was proposed for offshore natural gas hydrate (NGH) exploitation, whose feasibility was numerically evaluated based on a large-scale NGH reservoir situated in the Shenhu Area of the South China Sea. Then, two artificial means of well location rearrangement and hydraulic fracturing, as well as their combination, were proposed to be incorporated with seawater flooding to promote gas production from offshore NGH deposits. Simulation results indicated that seawater flooding had great advantages over depressurization and could substantially promote hydrate dissociation, effectively prevent secondary hydrate formation, and greatly facilitate gas production. Furthermore, a stable gas production period could be achieved for a long duration, which made the most significant contribution to gas production. The two artificial means of well location rearrangement and hydraulic fracturing could both promote hydrate dissociation and enhance gas recovery, but the promotion mechanisms were different. When these two methods were combined, hydrate dissociation in the whole hydrate-bearing layer could be further facilitated, and a favorable gas production rate could be obtained with a low water production and a high gas−water ratio, which demonstrated great superiority of the combined method over these two methods when used alone. Therefore, it is expected that the newly proposed approach of seawater flooding combined with well location rearrangement and hydraulic fracturing can be applied in the future commercial offshore NGH development.

“…In the conventional drying process, the direction of steam diffusion is opposite to the temperature gradient, which leads to spreading obstruction and heat transfer efficiency reduction. Microwave technology has effectively improved the current situation, during the drying treatment of the microwave, the water in the inner layer and the surface layer of the material is selectively heated by the microwave at the same time Mahmoud et al 2022;Manno et al 2023;Yadav et al 2022). The moisture will vaporize immediately after being heated, the temperature gradient and heat transfer direction inside the material are the same as the water vapor transfer direction, so it is characterized by internal and external heating, which shortens the drying time (Huang et al 2022;Li et al 2023).…”

The extraction and utilization of low-grade manganese ore can alleviate the industrial impact of the extreme lack of high-grade pyrochlore resources. The dry pre-processing of minerals is a necessary condition to ensure the safe and efficient operation of the subsequent extraction process. In this paper, green microwave technology was utilized for studying the dynamics of drying experiments at the different initial moisture content of 10%, 15%, 20%, 25%, 30%, and 35%, respectively. The experimental results explain that the initial moisture content of a mineral was positively correlated with its drying rate. Furthermore, the basic theoretical features and dynamics of microwave drying of manganese ore were discussed by fitting and analyzing experimental data with a model of thin-layer drying dynamics. The average correlation coefficient (R2) of the Quadratic model was 0.976. The RSS values obtained by fitting the Quadratic model were 0.01368, 0.01939, and 0.01986, respectively. Compared to the other two models, the Quadratic model can more accurately describe the microwave drying kinetic process of manganese ore than the other two models. Interestingly, the infrared spectrum tests indicated that microwave drying can basically remove the O-H bond, and the change of mineral weight in the drying process was entirely caused by water loss. Through microscopic characterization of minerals, it has been found that microwave drying can reduce the size of mineral particles, which is beneficial to the subsequent roasting and leaching process. The interesting and important findings from this work can be applied to explore more extraction methods for manganese.
