Source of acid mist-alkaline solution equilibrium data

I would like to ask everyone: In Chapter 3, Section 3.4.3 – Case Study, of the book \"Atmospheric Pollution Control Engineering\" edited by Shao Zhenhua, the design calculations for a packed tower used to absorb sulfuric acid mist with a 5% sodium hydroxide solution are discussed. In subsection 3.4.3.3, which deals with the calculation of the upflow velocity uf, it is stated that: (L/G)min = (y1 – y2) / (x* – x2), where x* = 0.000186 (this value is obtained from the equilibrium data on acid mist and alkaline solutions in design manuals). I have gone through all the materials I have, as well as searched online, but I was unable to find the source of the value x*=0.000186 mentioned above. Does anyone here know where this value comes from?
