TL;DR: In this paper, the authors presented an analysis for the degree of temperature departure between two pseudo-homogeneous models under plug flow conditions with no axial dispersion, and the analysis yields two important parameters: α, the ratio of solid to gas thermal capacitances, and β, which is closely related to the number of interphase heat transferase units.

TL;DR: In this article, solvent sublation in a continuous countercurrent mode for the removal of three hydrophobic organic compounds (viz pentachlorophenol, 2,4,6-trichlorophenols and naphthalene) from water into mineral oil was investigated using a steady state "stagewise" model along with the determination of key hydrodynamic parameters for the bubble column such as bubble radius and number of equilibrium stages.

Journal ArticleDOI
TL;DR: In this article, a dispersion model with mass transfer was solved to obtain the frequency response for a countercurrent liquid extraction column, and a least-squares method in the frequency domain was used to test the model against data taken on a laboratory column.

TL;DR: In this paper, a system for recovering water in high-humidity flue gas by contact-type circulating heat exchange and removing PM25 at the same time is presented, where the adsorbents can be recycled after contact heat exchange, so that the purposes of saving water resources and protecting the environment are achieved.
Abstract: The invention discloses a system for recovering water in high-humidity flue gas by contact-type circulating heat exchange and removing PM25 at the same time A contact-type heat exchanger is additionally arranged at an outlet of a desulfurization tower in a thermal power plant; a high-pressure overcooled liquid adsorbent enters the heat exchanger and is subjected to countercurrent contact-type heat exchange with desulfurization flue gas in a filler layer; and PM25 in the flue gas is attached on the pipe wall of the heat exchanger and immersed in condensed liquid, and flows down along with the condensed liquid to be collected A gas adsorbent is boosted through a compressor and condensed through a condenser to become high-pressure overcooled liquid; and the high-pressure overcooled liquid is filtered through a dry filter and decompressed through a throttle valve to enter the heat exchanger for continuing to circularly exchange heat with the desulfurization flue gas According to the system, the adsorbents are used for recovering the water in the desulfurization flue gas and performing capture settling on PM25 at the same time; and the adsorbents can be recycled after contact heat exchange, so that the purposes of saving water resources and protecting the environment are achieved
