An ELM data-driven model for predicting erosion rate of string in underground compressed air storage Process Saf. Environ. Prot. (IF 7.8) Pub Date : 2024-03-07 Xinhong Li, Fafu Tian, Jianjun Wang, Guoming Chen
Underground compressed air storage has experienced rapid development in recent years. The string, as a critical component of underground compressed air storage, serves as a channel for gas injection and production. The high-speed gas flow can cause string failure due to erosion. This study presents a data-driven model to predict the erosion rate of string in underground compressed air storage. A Computational

Comparative study on the nutrient recovery from source-separated urine using magnesium-air fuel cell in different operating modes Process Saf. Environ. Prot. (IF 7.8) Pub Date : 2024-03-07 Lin-Feng He, Shu-Jie Hu, Di Wu, Meng-Yue Zhang, Hong Liu, Yuan Liu
To address the paucity of phosphorus reserves, on-site resource recovery from urine was a viable approach in line with sustainable development imperatives. In this context, an electrochemically induced precipitation system based on the principle of Mg-air fuel cells (MAFC), capable of precipitating NH-N and PO-P as struvite from urine, offered an alluring prospect. Given the dilemma of the recovered

Thermal runaway propagation behavior and gas production characteristics of NCM622 battery modules at different state of charge Process Saf. Environ. Prot. (IF 7.8) Pub Date : 2024-03-07 Lejun Xu, Shilin Wang, Yitong Li, Yang Li, Junli Sun, Feng Zhao, Huaibin Wang, Yong Wang, Chengshan Xu, Xuning Feng
Due to the complex thermal runaway propagation behavior of lithium-ion battery modules and the generation of a substantial amount of combustible mixed gases during the process, their safety performance is compromised, hindering their large-scale application in the fields of energy storage and automotive industries. Therefore, in this paper, the thermal runaway propagation behavior and gas production
