Haiyou, could you please help analyze the problems encountered in the purification of acetylene? ?

1. I’ve never really understood what exactly is meant by effective chlorine in a purification tower; the concept is unclear to me. It was only gradually that I realized the strong oxidizing power of sodium hypochlorite, which stems from the reactivity of chloride ions; the efficiency inside the tower was kept between 0.08 and 0.12. Whenever the volume required for titration was met, it indicated that there was sufficient sodium hypochlorite solution inside the tower. 2. A problem that has been bothering us recently is the unexplained increase in the alkalinity level in the neutralization tower; the efficiency inside the tower has reached over 16, and it’s possible that the gas entering the tower is causing this effect. I’m not sure if this analysis is correct. 3. Our process involves using two purification towers, and other experts have also told me about the acceptable range for efficiency inside these towers. Normally, we measure the efficiency of the first tower through which the gas passes, while fresh liquid is added to the second tower. The flow of gas and liquid is in opposite directions; so, what would be the efficiency level of the second tower? ? It’s seriously beyond the limits, isn’t it? ? ? 4. I really need a table showing the relationship between efficiency and titration volume
