Competitive Behavior of Polar and Nonpolar Shale Oil During CO2-Induced Mobilization in Water-Bearing Nanopores

Abstract The efficiency of CO2-enhanced oil recovery (EOR) in shale reservoirs is critically influenced by formation water and the complex chemistry of the crude oil. However, the roles of components in shale oil and its underlying mechanisms are lacking. In this work, molecular...

Principles and Practical Measurement and Control Strategies for Achieving Ultrahigh CO2 Capture Rates in Amine Post-Combustion Capture Plants

Abstract This study presents a practical feedback control strategy for conventional amine post-combustion capture (PCC) plants that is capable of achieving up to around 100% added CO2 capture (i.e., the exit CO2 is equivalent to the CO2 in the combustion air) with moderate energy...

Thermodynamic Degradation and Life-Cycle Carbon Mitigation of a 350 MW Supercritical Coal-Fired Unit During Deep Peak Shaving to 20% Load

This study couples a plant-validated steady-state boiler–turbine model of a 350 MW supercritical unit with life-cycle carbon accounting, renewable-accommodation sensitivity analysis, entropy-weighted TOPSIS, and a constrained load-adaptive operating strategy over 100–20% load. Ma...

Integrating human linguistic insights into AI: theory-driven representation for multilingual text-to-speech

This paper explores the integration of human linguistic insights into multilingual text-to-speech (TTS) systems by evaluating the Featurally Underspecified Lexicon (FUL) as a theory-driven input representation. Unlike data-intensive end-to end models, FUL offers a compact, interp...

Study on Roof‐Control Technology for Gob‐Side Entry Retaining Under Composite Roofs

ABSTRACT This paper addresses the challenge of roof control during gob‐side entry retaining under a composite roof. Taking the 15210 working face of Hecaogou No. 1 Mine as the engineering background, borehole‐camera exploration, numerical simulation, and field measurements are in...

Calculation of water storage space and changes in underground coal mine reservoirs

In view of the limited limited water storage space and unstable structure in traditional caving mining, and the invisibility of goaf leads to the difficulty of accurate calculation of water storage space, this paper proposes a comprehensive technical method for the digitization o...
