【摘要】 提出了“三临二优”（系指临界操作压力比R~-、临界选择系数α~-、临界进料浓度x_f~-和最优操作压力比R~+、最优选择系数α~+）新概念,通过计算、分析和优化等手段,在x_f≥0.40、R≤100、a≤100范围内获得如下通用回归公式R~-=2+B/（α~-+A）,式中A、B仅与临界进料浓度x_f~-有关,并对他们分别进行了回归。此外,还在R≤1000、a≤1000范围内给出了x_f~-=0.95和0.50时的回归公式。更多还原

【Abstract】 Concepts of "the three criticals and the two optimums", i. e the critical operating pressure ratio (R-), selectivity coefficient (α-) and feed concentration (x1-) ,and the optimum operating pressure ratio and selectivity coefficient are first proposed. And through calculation, analysis and optimization in the range of x1≥0.4, R≤100 and α≤100, a general regression equation is obtained and shown as followsR-=2+B/(α-+A)where parameters A and B are related to x1- only, and the regression equations of xf- and A B are also obtained respectively. Moreover the following regression equations are obtained in the range of R≤1000and α≤1000R-=2+2. 15205/(α-)1.000568+2.07563 for xf-=0.95R-=2+6.2727/(α-)0.960+3.8307 for xf-=0.50更多还原
