摘要
对液相中伴有复杂反应平衡的高度非理想体系,平衡闪蒸计算宜采用联立求解问题的非线性方程组的方法。本文以二异丙醇胺-环丁砜-水吸收了H_2S、CO_2、CH_4的体系为例,构造非线性方程组进行联解,可直接一次求得结果,无需多层迭代,收敛速度较快,获得较满意的效果。
It is suggested that the method of solving related non-linearequations simultaneously should be adopted to flash calculation of highly non-ideal system with complex reaction equilibria existing in the liquid phase. The flash computution of aqueous di-isopropanolamine and sulfolane solution with H_2S, CO_2, CH_4 absorbed is carried out bythis method as an example. The results are satisfactory and the convergence is rapid.
