Problem 4. In this problem, we will walk through how to derive the Kremser equation from component mass balances. (a) In class, we showed that, when CMO assumption is valid, for any stage n and any component i, the term Vyin+1 - LXin is a constant throughout the column (we denoted this constant as de in class, which stands for the net material upward flow for component 1). Meanwhile, we know that yi,n+1 = KXintu and Yin - Kixin as well (VLE relation), assuming that the K-value K is constant throughout the column. Based on these two sets of relations, show that: Yi.N+1 - Yin 2) * Cia - .) u Hint: Start by writing down Vyin+1 - LXin for n = N and n= N - 1 and apply the VLE relation. Note that, once we convert yin and yio respectively to Kii.n and KX1,0 (which are physically present in the absorption column) using the VLE relation, we will recover the first form of the Kremser equation introduced in lecture. (b) Following the same procedure in Part a), derive the second form of the Kremser equation in terms of liquid compositions: YN+1 TEN KA 1.1 11 (65) X10 -Ki
