摘要
本文推导出最小回流比R_m与侧线采出流率S及热状况参数q_s之间关系式,指出在进料上方的侧线采出使二元精馏最小回流比R_m增加,最小回流比R_m计算为无侧线采出的最小回流比值加上因侧线采出所需补偿的值。
The article deduces the equation relating the minimum ieflux ratio R_m to the rate of side draw S and the sidestream thermal condition parameter q_s, and indicates that the sidestreams above the feed will increase the minimum reflux ratio in binary rectification. The actual minimum reflux ratio is calculated by adding the necessary compensating amounts due to sidestreams to no-sidestream minimum reflux ratio.
