摘要
文中介绍了GEAR法在粗酚间歇精馏计算中的应用情况,指出,该计算法的精度优于RONGE-KUTTA法,为避免用复杂的刚性微分方程组的求解,可用三对角矩阵代替。该法也适用于其他的间歇蒸馏过程。
The application of GEAR method to the calculation for the batch fractionating process of crude phenol is described in this paper,Pointing out that the GEAR method is more accurate than the RONGE-KUTT method,and that the tridiagonal matrix can be used to replace the complicated rigidity differential equation group for sulution. This GEAR met hod is also applicable to the batch distillating process for others.
