摘要
以活化碳酸钠溶液吸收二氧化碳的汽-液平衡分压为例,用最小二乘法和正交多项式,将一元拟合与二元拟合结合在一起,建立了汽-液平衡的一种有效算法,与实测数据拟合的很好,最大相对误差不超过3%.
Based on an application of the least square techniques combined with orthogonal polynomial expression,an algorithm was proposed to compute the gas-liquid balance problem commonly occured in various chemical reaction processes.A concrete example in the reaction process where CO, is absorbing by active NaCO3 liquid was computed.The computation shows that the proposed algorithm is very efficient.
