Hi,
I need to do a cost estimation for a thermal reactor of a sulphur recovery unit in a oil refinery. I am going to use the database of other plants. I'd like to know if, from the process point of view, I can use the information of a NGL or gas refinery as a reference or better say, if we assume that the capacity and the process conditions of 2 sulphr recovery units of 2 different refineries( one NGL, another oil) are identical, can we use one of them to estimate the size and consequently the price of the other one?
Thanks

Its been a while but I think you would be OK using that data base. I assume the H2S rich gas (AKA acid gas) was made using some kind of amine process, then the acid gas should be around 92-96 mol % H2S. There might be some nitrogen and some methane in the acid gas as well, but that is normal. You should get a second opinion or more, but this is a start.
