【摘要】 利用电解质气液相平衡的特点,建立了柠檬酸-柠檬酸钠缓冲溶液和SO₂系统的相平衡模型。以此种缓冲溶液为吸收剂,将高效规整填料应用于吸收塔和解吸塔,进行了全流程吸收-解吸试验。研究了在中试规模下解吸塔汽提解吸SO₂操作中影响解吸效率的若干重要工艺参数。对解决我国的SO₂大气污染问题提供了理论和应用的基础。更多还原

【Abstract】 : The model of citric acid - sodium citrate buffer in equilibrium with SO2 system is built up by taking the feature of electrolyte gas-liquid phase balance. The buffer used as absorbing agent will have high efficient iso-tactic packing served in absorption tower and desorption tower. Overall flow adsorption- and desorption test is carried out. Under the scale of pilot plant, some main process parameters affecting on desorption efficiency are studied in the operation to desorb SO2 by desorption tower stripping. Many theoretic and practical bases are presented for solving atmosphere pollution caused by SQ2 in our country.更多还原
