Corrosion behaviors of carbon steel in 55% LiBr solution containing PWVA inhibitor / X. Q. Hu in Materials and corrosion, Vol. 62 N° 5 (Mai 2011) 

Public ISBD [article]  in Materials and corrosion > Vol. 62 N° 5 (Mai 2011) . - pp. 444–448 Titre : Corrosion behaviors of carbon steel in 55% LiBr solution containing PWVA inhibitor Type de document : texte imprimé Auteurs : X. Q. Hu, Auteur ; C. H. Liang, Auteur ; X. N. Wu, Auteur Année de publication : 2011 Article en page(s) : pp. 444–448 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Corrosion  Corrosion  test  Inhibition  Inhibitor Index. décimale : 620.1 Essais des matériaux. Défauts des matériaux. Protection des matériaux Résumé : The inhibition performance of PWVA inhibitor on carbon steel was studied in 55% LiBr + 0.07 mol/L LiOH solution. Results indicated that PWVA inhibitor decreased both anodic and cathodic polarization current density and widened the passive potential region of carbon steel in the test solution. It could be classified as mixed inhibitor. PWVA has a strong oxidizability. It could form an intact and compact film which consisted of Fe2O3 on carbon steel surface in the test solution. The passive film retarded Br− which corroded the metal matrix in the test solution. When the concentration of PWVA was 300 mg/L, it showed an excellent inhibition effect. However, when the temperature was higher than 173 °C, the corrosion rate of carbon steel in 55% LiBr + 0.07 mol/L LiOH solution increased rapidly.

Independent air dehumidification with membrane-based total heat recovery / C. H. Liang in International journal of refrigeration, Vol. 33 N° 2 (Mars 2010)

H. Liang, Auteur ; L.Z. Zhang, Auteur ; L.X. Pei, Auteur Année de publication : 2011 Article en page(s) : pp. 398-408 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Air  conditioning  Dehumidification  Membrane  Heat  recovery  Modelling  Experiment Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : Fresh air ventilation is helpful for the control of epidemic respiratory disease like Swine flu (H1N1). Fresh air dehumidification systems with energy recovery measures are the key equipments to realize this goal. As a solution, an independent air dehumidification system with membrane-based total heat recovery is proposed. A prototype is built in laboratory. A detailed model is proposed and a cell-by-cell simulation technique is used in simulation to evaluate performances. The results indicate that the model can predict the system accurately. The effects of varying operating conditions like air-flow rates, temperature, and air relative humidity on the air dehumidification rates, cooling powers, electric power consumption, and thermal coefficient of performance are evaluated. The prototype has a COP of 6.8 under nominal operating conditions with total heat recovery. The performance is rather robust to outside weather conditions with a membrane-based total heat exchanger.
