Hello,
I am currently working on biomass and coal co-gasification, trying to study the effect of exeperimental parameters in the formation of H2S and HCl, and I am experiencing some difficulties in the quantification of these species.
As we have, after the gasifier exit, a quenching system, for tar removal, some of the gas condensates, and so does the sulphur that was in the raw gas(before the quenching system). So at the end of the day i kown how many grams of sulphur are retained in the condensates, but i have now ideia how much of this sulphur corresponds to H2S in the gas.
One possible way to solve this problem is probably through the use of Henry law, but I don't kow the constant value for H2S neither the parcial pressure of H2S. Another possible way is to sample the gas before the quenching system, the problem is that the gas in that point is very hot (750ºC) and loaded with tars.
So I am looking for suggestions, and will be very pleased if anyone could help me. Thank you
