TL;DR: In this article, an improved CO2 separation and purification system is proposed based on in-depth analyses of cryogenic separation and distillation theory as well as the phase transition characteristics of gas mixtures containing CO2.

TL;DR: In this article, the authors conducted a thermodynamic analysis and optimization design of the heat recovery system using boiler exhaust gas in coal-fired power plants, and some recommendations on optimization design parameters were proposed, with full consideration of various factors such as the decrease on fuel cost due to energy conservation and the investment cost of heat recovery retrofitting.

TL;DR: In this paper, the particle sizes and sintering temperatures of the top surface deposits were also determined at probe temperatures of 773 K and 873 K, where fine particles had melted and incorporated into the coarse particles and the formation of a new mineral phase with low melting-point, hauyne (Al6Ca2Na6O32S2Si6).

TL;DR: In this article, the phase transition characteristics of CO 2 and CO 2 /H 2 mixture are analyzed, and ideas for improving the cryogenic separation method are drawn, and a novel CO 2 cryogenic liquefaction and separation system is put forward.

TL;DR: In this paper, the sintering and fusion characteristics of pulverised Zhundong lignite and its blends combusted at different temperatures in a muffle furnace were investigated.
