Hi,

Anyone has experience in simulating turboexpander with hysys dynamic? I succeed in converge steady state simulation inputting expander and re-compressor curves but solver fail when I switch to dynamic. Plant is a simple LTS, between expander and re-compressor there are a separator and gas/gas exchanger. I suspect solver fails because using curves as dynamic specification for both expander and re-compressor gives arise different values for the pressure between expander and re-compressor.
