求教,以下东西在吸收塔里边的设置。? 找了一份 吸收塔 的资料,不知道这些东西在哪里设置。大侠留步解答。 7. Mass transfer coefficient method: Bravo et al (1985) 8. Interfacial area method: Bravo et al (1985) 9. Interfacial area factor: 0.6 10. Heat transfer coefficient method: Chilton and Colburn 11. Holdup correlation: Billet and Schultes (1993) 12. Film resistance options: Discrxn for liquid film, and Film for vapor film 13. Additional discretization points for liquid film: 0.0001, 0.001, 0.01, 0.1 and 0.5 另外 4. Reaction: Reaction ID is K2CO3-R for all stages; when calculation type is equilibrium stages, Residence Times is used, and in this file, the liquid Residence time = 0.001s 停留时间是指一块塔板上的还是全塔的,还是另有玄机,各位帮帮忙了。查看更多7个回答 . 3人已关注
