Based on column heat load and column temperature difference, rules of thumb are proposed for judging the economics of distillation systems with heat-integration. After determining the best separation trains, the new rules of thumb are capable of assigning a small number of near optimal heat integrated schemes for the most promising sequences. The primary value of the new rules is to provide quick initial schemes with heat integration for evolutionary synthesis methods. The effectiveness of the rules of thumb is demonstrated on a separation problem of light hydrocarbons. The results obtained by employing the new rules of thumb are identical to the distillation schemes provided by synthesis strategy, including optimization.
